According to the 1912 Department of Mines Bulletin of the Geological Survey of Victoria, basalt covers a considerable portion of the Macedon area including Mount Macedon. Basalt is the most common form of rock underlying the earth's surface and is found in three kinds of rock forming environments: ocean divergent boundaries, oceanic hotspots, and mantle plumes and hotspots beneath continents.This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.A solid mass, geological specimen in shades of grey and white. Hyalite is a colourless variety of opal. It occurs as globular and botryoidal masses and irregular crusts in volcanic and pegmatite environments where the silica deposits from the gas phase. Basalt is dark in colour, fine-grained igneous rock composed of plagioclase and pyroxene minerals. It is commonly formed as an extrusive rock, such as lava flow. It is one of the most common forms of rock underlying the earth's surface.burke museum, geological specimen, department of mines, geological survey of victoria, basalt, mount macedon, beechworth

Alex Pittendrigh completed a degree in painting at the Victorian College of the Arts in 1994, was awarded an Australia Council residency at The British School in Rome and was a resident artist at Gertrude Contemporary Art Spaces. In his series of three artworks, 'Worlds through worlds III', 'Worlds through worlds IV' and 'Phenomenon', the scenes appear as if extricated through a kind of portal or void. They are landscapes as imagined or perhaps remembered, ‘pictured’ in the mind’s eye. Seen as an exercise in rococo excess and ornamentation, these artworks suggest a tension between the ornamental and pictorial. The decorative filigree within the painted surface set these scenes further away from the real world. They are ideal, and idealised, places that remain at a distance.In this dark landscape-like image, viewed from above, is a central pale yellow shape, bordered irregularly by twig-like forms, which is perhaps the earth, shone on by a moon in the top right. Ornamental vegetation - leaves, grapes - appear to be spinning off the earth into corners or out of the frame.

This specimen was recovered from Ceres West of Geelong, Victoria. Greenstone is the name for any metamorphosed basic igneous rock (in the case of this specimen, Gabbro) that gains its greenish colour to the presence of the minerals chlorite, actinolite, or epidote, hence the term 'green' and 'stone'. Greenstone is often formed through metamorphsis along a convergent plate boundary. In the rock cycle (the series of processes that creates the various types of rocks) there are identified three different types of rocks, which are the sedimentary, the igneous and the metamorphic. Metamorphic rocks started out as sedimentary, igneous or earlier metamorphic rocks but changed from their original condition under the effect of high heat, high pressure or hot, mineral-rich fluid. However, if pressure or heat is too high, then the rock will melt, resulting in the formation of an igneous rock. The name used to describe these types of rocks reflects this specific inherent trait of change, since the word “metamorphic” derives from the Greek word “metamorphosis”, meaning “change of form or structure”. Metamorphic rocks form in the Earth`s crust but can be also found on the surface, due to elevation of the Earth`s surface. They are divided into two categories: the foliated metamorphic and the non-foliated metamorphic rocks. Gabbro is a highly useful mineral that is often polished to create cemetery markers and kitchen benches. It is notable for its qualities of durability, being able to withstand extreme elements and wear. Whilst not rare, Gabbro is of great utility and has been highly desirable for its qualities.

This field telephone was developed primary for military purposes (World War I) and other wars/military interventions there after. It was the first "mobile" telephone which had a prime objective of providing isolated or "hard" to connect with locations instant communication links. Like a lot of "new" technologies it evolved from a war environment. This handset was used to connect offices and workshops, which due to their functions could not be co-located with their prime office(external workshops).The evolution from the early 1900s to the mid 1980s when mobile communication technology progressed in leaps and bounds from hard wire telephone communication to mobile digital receivers. This handset was manufactured by a subcontracted Australian company under the Australian Post Office mandate.This handset is significant in that it was donated by the Mount Beauty Timber yards and formed an integrated part of its communication system with its out lying work yards and buildings, before the mobile handset evolution. This handset was located in an environment which required a rugged and reliable day to day communications linkage as a vital part of its logistical (business) survival. As progress demands it, the faster that customers are satisfied with the service they obtain from suppliers the longer those services will be asked for and the longer and more profitable the supplier will be. This edict is as true for rural companies as it is for small or large city businesses. The customer is "always" right.This sturdy field telephone has a shell housing made in black bakelite material with a "U" form housing the major components (wiring, magneto and batteries). The main housing has two metal bells, with a central ringer between both, on the top part (to notify incoming calls). In front of the main structure is a box with the telephone hand piece (ear and mouth receptacles) nestled on two cradles. An on/off switch is activated when handset is removed from its cradle. On the front of the control box is a winder handle(to ring off) and in a field situation to activate/deactivate the magneto. To the left of the winder but on the the main body are two wind up connection buttons for the connection of operational wires (power)On the main right hand front body and next to two chrome switches is a plate with "L (next to the top switch) and below this "L2" and underneath this are "or" "EARTH". There is a plate fastened to the front of the handset and behind the winder with "REPLACE HANDSET WHEN FINISHED" and below the winder 'SERIAL NUMBER 5116"field telephone, world war ii field telephone f mk i

This sniper shield may have been used by German troops during the First World War. There are few other examples of sniper shields of this shape or style, so it was possibly not a widely used design.Metal sniper shield constructed of a large flat front with curved edges, onto which a handle-like piece is soldered on one end and bolted on another. This handle has a pin which presumably adjusts the height/angle of the shield in relation to the ground. The third piece of the shield is a stand with a curved end, presumably rests on the ground, and on the other end a series of five holes which adjust the height/angle. The shield itself is roughly square in shape with a rectangular cut out off-centre at the top and a larger rectangular cut out at the base, which forms two pointed ends, possibly for securing into earth like a peg."G-01" is inscribed in ink, a registration number rather than historic inscription.germany, first world war, world war i, world war 1, the great war, sniper, firearm

THE AUSTRALIAN TRUST OF CONSERVATION VOLUNTEERS, ONE OF 14 INDIVIDUALS AND ORGANIZATIONS, TO RECEIVE UNITED NATIONS ENVIRONMENT AWARD NAIROBI, 1 June 2000 - The United Nations Environment Programme (UNEP) announced today that the Australian Trust of Conservation Volunteers of Australia (ATCV), has been elected to the prestigious ranks of its Global 500 Roll of Honour for outstanding contributions to the protection of the environment. ATCV is one of 14 individuals and organizations to receive this honour in 2000. Founded in 1982, ATCV is a national, not-for-profit community organization, whose mission is to attract and manage a force of volunteers in practical conservation projects for the betterment of the Australian environment. ATCV completes more than 4000 week-long conservation projects in urban, regional and remote areas of Australia each year. Activities range from bush regeneration, tree planting, seed collection, endangered species protection, weed control, flora and fauna surveys, walking trail construction, fencing, environmental monitoring and the protection of world heritage areas. ATCV community participation has resulted in more than 1.8 million trees being planted in 1999, and in more than 7.3 million trees planted over the past 10 years. Community involvement totalled 200,000 project days in 1999 and more than 700,000 days since 1989. To encourage the involvement of young people, ATCV developed and manages the federal government-funded programme Green Corps. Green Corps is a six-month traineeship for 17 to 20 year-olds, which incorporates conservation projects and accredited training. Since 1997, more than 4,000 trainees have completed the Green Corps programme. ATCV is a founding member of the International Conservation Alliance, which brings together organizations working in conservation volunteering, and is a member of the World Conservation Union (IUCN). " The award will be presented in Adelaide, Australia, at the World Environment Day ceremonies on 4 June 2000. World Environment Day, which is celebrated in some 120 countries around the world on 5 June, was established by the United Nations General Assembly in 1972 to focus global attention and action on environmental issues. Some 701 individuals and organizations, in both the adult and youth categories, have been honoured since UNEP launched the Global 500 award in 1987. Among prominent past winners are: French Marine explorer Jacques Cousteau; Sir David Attenborough, producer of environmental television programmes; Gro Harlem Brundtland, former Prime Minister of Norway; Anil Aggarwal, the prominent environmentalist from India; Ken Saro-Wiwa, the environmental and human rights activist from Nigeria who was executed for leading the resistance of the Ogoni People against the pollution of their Delta homeland; the World Wide Fund for Nature (WWF), Jimmy Carter, former President of the United States; Jane Goodall of the United Kingdom whose research on wild chimpanzees and olive baboons provided insight into the lives of non-human primates; and the late Chico Mendes, the Brazilian rubber tapper who was murdered during his fight to save the Amazon forest. To forge global links and to implement ideas, which can contribute to a more sustainable future, a network of all Global 500 laureates has been formed. Information about this unique network can be obtained at http://www.global500.org. The winners of UNEP's Global 500 Roll of Honour are members of a broad and growing environmental movement that is flourishing around the world. They have taken the path that most of us hesitate to take for want of time or caring," says UNEP's Executive Director, Klaus Toepfer. "In honouring the Global 500 laureates, UNEP hopes that others will be inspired by their extraordinary deeds."Certificatecva, conservation volunteers, conservation volunteers australia, conservation volunteers new zealand, colin jackson, better earth, environmental conservation, volunteers, volunteering, corporate volunteering, education – environmental, carbon footprint, climate change, ballarat, safety, training, partnerships, victoria, vic, nsw, queensland, act, australian capital territory, nt, northern territory, western australia, wa, south australia, sa, tasmania, new zealand, california conservation corps, atcv, unep, unep honour roll, united nations environment program

Plum Cottage is covered by Heritage Overelay HO256 in the Nillumbuk Planning Scheme This two-lot land holding was created as a subdivision and sold to Charles Stuart McNeil by May 1955. Sometime in the period 1955-1960, the builder-designer, John Harcourt had created a pise house on the site, straddling the two subdivision lots. The designer, John M. Harcourt was a pioneer builder in pise-de-terre and mudbrick in the Eltham Shire, Eltham being synonymous with alternative lifestyles and building practises until the onset of suburbia in the late 20th and early 21st centuries. This hipped-roof house is set high above Main Road on a V-shape plan characteristic of the Arts & Crafts style, with rammed earth or pise walls, timber joinery and a cement tiled roof. The V shape plan was used by important English and Eltham Arts & Crafts designers. The use of natural materials such as stone and timber construction is an essential part of the Arts & Crafts style and Harcourt’s work. So too is the application of the style on both the exterior and interior of the house as a holistic concept. The house adjoins the Lim Joon adobe house built and designed by Alistair Knox in the same era (HO119), thus forming a distinctive pair, both using an uncommon plan form. This house was identified in the Shire of Shire of Eltham Heritage 1992 as contributory to the Eltham Gateway Conservation Area, then proposed as an urban conservation area (now Heritage Overlay Area). Land Ownership Emily Jane Smith of 12 Woodside Street Fitzroy owned Crown Allotments 1 & 2 Sections 14, 27 by August 1918, selling to William Henry Smith of 12 Woodside Street, Nth Fitzroy May 1921. (John) James Isherwood of Main Road, Eltham owned the property by 1928 (the year of his death) with the beneficiary of his estate and next owner of this site being his widow, Minnie Maria Isherwood of Cemetery Road, Eltham. His holding in Main Road included parts of what was described in rate records as allotments1 & 2 Section E6. In the late 1930s, early 1940s her son Alfred John Isherwood was also rated for the land around this site, with the rated nett annual value varying between £2 and £5. Alfred Isherwood also lived at Main Road, Eltham with his wife Ellen: her early death at the age of 24 was reported in the Argus of 1923. Part of the Isherwood land was divided off and sold to Charles Stuart McNeil by May1955. Sometime in the period 1955-1960, the builder-designer, John Harcourt had created a pise house on the site, straddling the two subdivision lots. The house is visible on an aerial photograph from 1960s. Reputedly the house was called Plum Cottage and erected for Harcourt’s mother-in-law. A garage was added in 1959. Charles McNeil died in1971 aged 87: he was the son of Don McNeil and Margaret Arkell. Available rate records from the construction era start in the of the 1970s (1972-3) and list Mr H.C. & M/S A.V. Charity at 616 Main Road Eltham of this property with a nett annual value of $740. More recent valuer's data describes the property as lots 1 & 2 LP25668, located in the Central Riding of Eltham Shire, owned by Ann Valerie Charity and later, in 1990, by the Chincarini family. Building Description This hipped roof 11 .5 square house is set high above Main Road on a characteristic-shape plan and has rammed earth or pise walls, timber joinery and a cement tiled roof. The V-shape plan was used by Important designers such as C.F.A. Voysey (UK) who interpreted medieval domestic architecture as part of the Arts & Crafts style of the late 19th and early 20th centuries. The pise walls are covered with a textured render while the cement roofing tiles are also seen in the Harcourt Hill examples. Reputedly the ceiling joists are of a deep section and span long lengths with no need for hanging beams in the roof space. The ceilings are low and panelled in main rooms with apparently Caneite soft board infill panels between the exposed ceiling beams. These are painted white but may have been stained at one time. The focus of the house is the large living area with its vast random stone fireplace. Significance Plum Cottage is significant to the locality of Eltham because: Historically: • Plum Cottage is closely associated with the important historical theme of earth construction evident in Eltham and elsewhere in the Shire since theear1y Arts & Crafts inspired creations at Penleigh Boyd's The Robins (1912, HO101) and those at Montsalvat (1934-, HO82) but more prominent from the Second War period when earth building in Eltham was promoted in national periodicals as an alternative building method that avoided the building materials shortages of that era; • The choice of the earth building technique also expresses the theme of refuge or alternative living, synonymous with Eltham in the early to mid 20th century; • as a good example of domestic architecture from John Harcourt who was the first major post Second War figure in an important phase of Eltham’s earth building development, using his characteristic Old English or Arts& Crafts style that relies in this case on the pise wall construction, pitched roof forms, exposed ceiling joists, half timbering, random stonework, and panelled internal wall finishes. Architecturally: • Plum Cottage's pise wall construction is uncommon among the early earth-walled structures in the Shire, that are mainly of adobe or mud brick, and as a building material is uncommon among the Shire’s suburban dwellings generally which are clad typically with either fired clay bricks or timber boarding. Aesthetically: • Plum Cottage is a good and well preserved example of a modern Old English or Arts & Crafts style earth-walled building in the Shire • For the proximity of the significant Lim Joon adobe house designed by Alistair Knox adjoining to the north, providing a distinctive earth wall house pair, with uncommon plan forms.

Considered the best of the early mud-brick houses built by Alistair Knox. Covered under Heritage Overlay, Nillumbik Planning Scheme. Published: Nillumbik Now and Then /​ Marguerite Marshall 2008; photographs Alan King with Marguerite Marshall.; p143 The Busst house hidden by trees at the corner of Silver Street and Kerrie Crescent is considered the best of the early mud-brick houses built by Eltham architect, Alistair Knox. Knox himself said, that the Busst house was the most mature mud-brick house designed at that period. ‘It related with true understanding to its steep site and expressed the flexibility of earth building ………to develop a new sense of flowing form and shape’. Built in 1948 for artist Phyl Busst, a former art student at Montsalvat, the house helped usher in Eltham Shire’s distinctive mud-brick residential character. Knox was the pivotal figure of the style developed from the 1950s to the 1970s. Scarcity of building materials after World War Two encouraged mud-brick building because earth was a cheap and plentiful building medium. But when Knox began building in mud-brick in 1947, no council in Victoria knew anything of this ancient art and he needed a permit. Fortunately the Commonwealth Experimental Building Station at Ryde in NSW, had been experimenting with earth construction to help overcome the shortages of that time. They published a pamphlet that became available in Melbourne on the same day the Eltham Council was to consider whether the earth building should be allowed. Knox caught one of the three morning trains to the city in those days and bought several copies of the pamphlet to give to each councillor. On his return he found the councillors standing on the steps of the shire offices after lunch at the local hotel. He heard that earth building had been discussed before lunch and that they were not in favor of it. Knox gave each councillor a pamphlet. They passed that plan and by doing so, opened the door for all future earth building in Victoria and by default, in Australia. Mud-brick houses attracted artists to Eltham, for their aesthetic appeal and because they were cheap. Those who built their own houses, included film maker Tim Burstall, artists Peter Glass, Clifton Pugh, Matcham Skipper, Sonia Skipper and husband Jo Hannan. For Knox, mud-brick building was more than just a cheap building medium. He saw it as harmonising with the surrounding bush and as a way of counteracting the growing materialism of the age. He wrote of its impact on ‘ 20th century man. It should counteract the confusion that the perpetual flow of high technology products have upon him ..’ Building the Busst house on a steep site was difficult because most earth-moving equipment was then in its infancy. For instance drilling for explosives was done by hand, which was a slow and painful process. Knox, assisted by his foreman Horrie Judd and Gordon Ford (who was to become a famous landscape designer), built two large main rooms - a living room/ kitchen downstairs - and upstairs, a studio/bedroom. The studio/bedroom opens onto the balcony, which covers the living area. The bath made of solid concrete by stonemason Jack Fabro, is particularly deep. Sunshine pours through the three French windows of the north-east facing kitchen/living area, which is lined with timber. The large hearth can fit a family around the fire while the timber floors and solomite (compressed straw) ceilings add to the cosy atmosphere. The garden is thick with trees, and in the late 1990s, Ford put in a pool near the original dry wall he had built as a young man.This collection of almost 130 photos about places and people within the Shire of Nillumbik, an urban and rural municipality in Melbourne's north, contributes to an understanding of the history of the Shire. Published in 2008 immediately prior to the Black Saturday bushfires of February 7, 2009, it documents sites that were impacted, and in some cases destroyed by the fires. It includes photographs taken especially for the publication, creating a unique time capsule representing the Shire in the early 21st century. It remains the most recent comprehenesive publication devoted to the Shire's history connecting local residents to the past. nillumbik now and then (marshall-king) collection, alistair knox, alistair knox design, busst house, kerrie crescent, mudbrick construction, mudbrick houses, silver street

Baron von Richthofen (the Red Baron) was shot down on 21 April 1918 near the Somme River. He was buried with full military honours at Bertangles by members of the Australian Flying Corps. That night the flowers and cross were removed by local residents. The grave was reconstructed the next day by local soldiers. This postcard shows the grave on the day after the burial without the original cross. The original cross was was fashioned from an RE8 propeller by 3SQN mechanics with an engraved aluminium plaque. The plaque was engraved by Harold Edwards, a watchmaker from Bendigo. https://www.3sqnraafasn.net/subpages/edwardsstory.htm Richthofen's body was moved several times before he reached his final resting place in Germany. In 1925 his body was exhumed and buried in Berlin, Germany. Later, it was exhumed again and buried in the Richthofen family's private tomb.Postcard, WW1, black and white image of the grave of the German airman, Baron von Richthofen.

This specimen was recovered from the Nigretta Falls (previously named the Upper Wannon Falls), Victoria. The falls are fed by the Wannon River that has its head waters in the Grampians mountains. Approx. 10km upstream of the Wannon Falls, Nigretta is a multi-channel segmented cascade of smaller drops and bounces guided by patterns of joints in a much older (Devonian) rhyolitic volcanic rock. Both the Wannon and Nigretta Falls are iconic landscape features, entrenched in the history and identity of the region. These falls are particularly rare as they are the product of volcanic activity, which is unique in the context of the Volcanic Plain of Victoria. Waterfalls of this capacity are generally associated with the Uplands areas of Victoria, rather than the edges of the Volcanic Plain. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.

Rhodonite is a reddish-pink manganese silicate material and often contains iron, magnesium and calcium. It is usually found in metamorphic rocks (rocks which have been altered by heat, pressure or chemical process). It can range in size from tiny to massive. Because of their composition they are not suitable for use in jewellery because they are hard enough. It is quite rare to find, though has been found in Australia, North America, South America and Europe.This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

This specimen is a palm shaped piece of loellingite within rhodonite. It is mostly reddish-pink coloured, with flecks of light and dark grey. Loellingite is a grey iron arsenide which often forms into crystal shapes. It is mostly found in mesothermal veins (caused by immense heat) with sulfides or in limestone. It is toxic when heated or struck. rhodonite, loellingite, burke museum, beechworth, geological survey of victoria

This specimen was recovered from Silverton Mine in Broken Hill, New South Wales. Otherwise known as the 'Day Dream Mine', the Silverton Mine was first established in 1883, when silver and lead deposits where discovered. Within a few short years, the population of Broken Hill reached 3000 people. As of today the Silverton Mine is still open, and has produced over 200 million tonnes of ore, which has generated over $100 billion. The Silverton Mine was also famous for a number of specimens such as silver, iron and zinc.Copper is considered to be a rare ore in that finding it in its pure form is rare. Nowadays when mining for Copper it is often found in mixed in with other minerals or it is recycled from use. Moreover, Copper is found in a range of everyday uses such as coins, cookware, pipes, heating conductors and anything that generate electricity. The fact that Copper is heat a heat conductor, electricity conductor and it does not corrode easily, makes this ore a versatile and useful. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Copper is typically found as nuggets in the ground. It can be found in a range of forms such as its native state; mixed with other ores, such as zinc and iron; as porphyry copper deposits; and as major deposits. Porphyry deposits are when the mineral is scattered evenly throughout the rock. Major deposits are when the mineral is scattered amongst other minerals.burke museum, beechworth, indigo shire, beechworth musum, geological, geological specimen, mineraology, copper, copper ore, copper ore speciment, broken hill, new south wales

This particular specimen was recovered from the Lal Lal Coal and Iron Mine in Victoria, 19km from Ballarat. Brown Coal was discovered here in 1857, just alongside the Geelong to Ballarat Railway line. This discovery of lignite (brown coal) was the first in Victoria, which would bring important benefits to the region and state, both of which had previously been reliant on coal imports. In the 1860s, iron ore was found just 5km from Lal Lal, and the area was converted into an Iron Ore Mine. The Lal Lal Iron Mining Company took over operations in 1874, who then peaked iron production in 1884. This mine continued operations until June 1884, when the blast furnace was extinguished and never recommenced. The blast furnace at Lal Lal is considered one of the most important and highly significant sites ion early industrial history in Australia, as it is the only remaining best furnace from the nineteenth century in the Southern Hemisphere. The furnace ruins are 17 metres high, and are clearly visible today on Iron Mine Road, Lal Lal, near the Bungal Dam. This specimen of Lignite (brown coal) is significant, as it was mined from the area where brown coal was first discovered in Victoria, leading to an important and controversial future of the mining and use of brown coal in this State. The Victorian Heritage Database has listed the Lal Lal Coal Mine with local significance, with their Statement of Significance stating: "The Lal Lal coal mine is historically significant as the site of the first discovery of lignite (brown coal) in Victoria, and one that promised important benefits to regional and state industries that were reliant on coal imports at the time. The significance of the stie is reduced by the poor state of preservation of the coal mining and processing fabric". This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.A hand-sized light-weight, soft and combustable sedimentary rock specimen, that is dark brown in colour. The specimen has jagged edges, as though parts of the rock have crumbled away. Brown coal, or Lignite, is formed naturally from compressed peat, and is typically found in natural basins. The stages to the formation of coal ('coalification') begin with plant material and wood, which will decay if it is not subjected to deep burial or heating, and turn into Peat. Peat, when sufficiently compressed naturally, will turn into Brown Coal (Lignite), and finally into Black Coal (sub-bituminous, bituminous and anthracite). Each successive stage has a higher energy content and lower water content. It is brownish-black in colour. Brown Coal has a high moisture content, between 50 and 75 percent, and a low carbon content. Some Brown Coals may be stratified, with layers of plant matter, which means little coalification has occurred beyond the peat natural processing stage. When Brown Coal is submerged in dilute nitric acid or boiling potassium hydroxide solution, it reacts to produce a reddish solution, of which higher-ranked coals do not. When brown coal is pulverised and burned in boilers, the steam is used to drive turbines, which generates electricity. It is the lowest rank of coal, as when burned, it creates a relatively low heat content, which in turn does not create a great output of steam. burke museum, beechworth, indigo shire, beechworth museum, geological, geological specimen, mineralogy, brown coal, brown coal specimen, lignite, lal lal, lal lal coal mine, lal lal iron mine, ballarat, blast furnace

In Australia, precious opal is found in Cretaceous age sandstones and mudstones. These sedimentary rocks were deeply weathered and this weathering released silica into the groundwater.Australia is the only part of the world where opalised animal and plant fossils have been found. Opal artefacts several thousands of years old have been discovered in East Africa. As early as 250 BC the Romans prized opals, thought to have come from mines in Eastern Europe, the ancient world's main source of opals. There are many aboriginal dreamtime stories that feature opal. Australian opals discovered during the late 1800's found little favour with European markets but their commercial value increased in the 1900's and in 1932 Australia took over as the major producer of opals in the world and remains the largest producer to this day. Opal is found around the world (Brazil, Mexico, Honduras and the western US) however Australia produces 95% of the world's precious opal and it is our official national gemstone. Opal was first mined commercially at Listowel Downs in Queensland in 1875 and later at White Cliffs in NSW. Today, Coober Pedy (SA) is the main producer of white opal, though in recent years this field has expanded and all types of opals are found. Other centres in SA include Andamooka and Mintabe. Lightning Ridge (NSW) is renowned for black opal and formerly White Cliffs was a large producer of high quality opal. Boulder opals (opals in concretionary ironstone) are mined in Queensland from numerous localities in a zone extending from the Eulo and Cunnamulla district in the south and northwest for a distance of over 700 km to Kynuna in the north. The towns of Quilpie, Yowah and Winton are the main opal mining and wholesale centres. Opals are considered gemstones and have been used in jewellery for thousands of years.Throughout much of history, opals were actually believed to be good luck. The Romans thought that opals were one of the luckiest gemstones and a symbol of hope. In the Middle Ages, opals were believed to be bestowed with all the positive properties of coloured gemstones due to its rainbow-like play of colour. Finally, there is a superstition that you should not wear an opal unless it is your birthstone otherwise misfortune will befall you. This, of course, is far-fetched, but the notion could have been promoted in the late 19th and early 20th Centuries by diamond traders who were trying to increase sales of diamonds and deter people from buying opals. Possibly related to this is the thought that you should set opal jewellery with diamonds as their powers of good fortune will override any negativity held by the opal. The great majority of opal does not show play of colour and is called common opal or potch however this is not the case with a precious opal. Opal is a precious gemstone, like rubies, emeralds or diamonds. Opal is rare, and it is expensive to prospect and mine for.Silica is one of the most common minerals on the planet, but precious opal is very rare – far more rare than diamonds. Precious opal is rare because the natural processes that create it rarely occur.Most (at least 95%) of the opal found by miners is common opal without gem colour. In Australia we call it potch. It can be white, grey, black or amber coloured. Even when a miner finds gem-coloured opal, most of it can’t be cut into gemstones because it’s too thin, or sandy. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.It is not known where this opal originated, except that it is probably from Victoria, as it has been recorded from many localities in the State. Common Opal is formed from silica-rich water circulating through rocks near the Earth’s surface. It consists of minute spheres of silica arranged in different ways. In common opal, the spheres are of different sizes and randomly arranged, unlike in precious opal where the spheres are of similar size and uniformly arranged in three dimensions. These differences account for common opal generally being translucent to opaque and without the play of colours, or opalescence, displayed by precious opal. Common opal is found in many localities and different geological environments throughout Australia and the world. Precious opal requires special conditions to form and is much less common. Australia produces most to the world’s precious opal. burke museum, beechworth, indigo shire, beechworth museum, geological, geological specimen, precious opal, opal, brazil, mexico, honduras, queensland, coober pedy, gemstones, jewellery, play-of-colour, light blue

Basalt is a common igneous rock that composes most of the Earth's surface and can be found on the Moon and other rocky planets of the Solar System. It is generally composed minerals such as calcic plagioclase, clinopyroxene and iron ore which form grains that are indistinguishable to the naked eye. It can be dark grey or black in colouring and sometimes may contain holes left by gas bubbles. Most of the Earth's basalt was produced in environments such as oceanic divergent boundaries, oceanic hotspots, and mantle plumes and hotspots beneath continents. Basalt is commonly used in construction where it is crushed and used for multiple purposes such as concrete aggregate, road base, or railroad ballast. Thin slabs of basalt can also be cut and used for floor tiles, stone monuments, and building veneer. This particular specimen was excavated from Talbot in Victoria, which was a small gold mining town established in 1852. As basalt is a common rock, it is not specific to Talbot. However, this specimen can be assumed to be of the Cainozoic age due to previous geomorphic surveys of the area. This particular type of Basalt was used mainly for roads due to the durability of the rock.Basalt holds significance due to the continued use of the rock from historic until present times. The rock has been utilised for many types of construction and is still used for the same purposes today. Basalt also has significance to the Earth and other rocky planets of the Solar System as it makes up most of the planet's surface. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

This particular specimen was recovered from two hundred feet down in the Golden Mile in Kalgoorlie, Western Australia. The Golden Mile, named after the estimated sixty million ounces of gold worth around one hundred billion dollars, was the birthplace of the largest gold rush in Australia almost one hundred and thirty years ago when William Brookman and Samuel Pearce leased the Great Boulder mine. The Golden Mile is also the home of the Super Pit, Australia's most well-known mine.The majority of gold deposits will form as a native metal, however, on occasion, it can form a compound with another element, in this case, sulphur. Therefore, this specimen is a rare example of gold naturally forming into a compound mineral with sulphur. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria.

Precious metals are often found in Sulphide Ores, as sulphides usually bind to these metals. They are also extremely symmetrical in crystaline form. Gold-Sulphide Ore occurs when gold forms a natural compound with other elements. In this form, gold can be present in one of two ways. It can be fully immersed in the sulphide, or a portion may be partially free. This specimen has minimal gold visible, with only a few flecks being partially visible.burke museum, beechworth, indigo shire, beechworth museum, geological, geological specimen, mineralogy, gold-sulphide ore

This particular geological specimen was found in Mount Franklin or Lalgambook in Djadjawurrung, located between Daylesford and Newstead, approximately ninety minutes drive from Melbourne. The mountain is an example of a breached scoria cone (a steep conical hill of loose pyroclastic fragments) which was created by a volcanic eruption about 470,000 years ago, a date which may indicate the age of this geological specimen. The volcanic eruptions of Mount Franklin were most likely witnessed by members of the Dja Dja Wurrung Aboriginal tribe, who referred to this country as the 'smoking grounds'. Mount Franklin and the surrounding area appears to have been a place of considerable religious significance to Aboriginal people, there is evidence which indicates that frequent large ceremonial gatherings took place in the area. Basalt is the most common rock on Earth’s surface, more than 90% of all volcanic rock on Earth is basalt. Basalt is an aphanitic extrusive igneous rock formed from the rapid cooling of low-viscosity lava exposed at or very near the surface of a rocky planet or moon. Specimens are black in colour and weather to dark green or brown. Basalt is rich in iron and magnesium and is mainly composed of olivine, pyroxene, and plagioclase. Olivine is the name of a group of rock-forming silicate minerals with compositions ranging between Mg2SiO4 and Fe2SiO4. Unlike other minerals, Olivine has a very high crystallisation temperature which makes it the first of the minerals to crystallise from magma. As magma cools, the crystals begin to form and settle on the bottom of the lava and form basalts that are abnormally enriched in olivine in the lower part of lava flows. According to H. M. King (on geology.com) "Olivine is thought to be an important mineral in Earth's mantle. Its presence as a mantle mineral has been inferred by a change in the behaviour of seismic waves as they cross the boundary between Earth's crust and mantle". Lava from Mount Franklin and other volcanoes in the area filled valleys and buried the gold bearing streams that became the renowned ‘deep leads’ of the gold mining era. In 1852, as part of the Victorian gold rush, gold was discovered in the immediate area, this gold was created by lava flows during the Newer Volcanic period, which were mined intensively during the nineteenth century. Around 1865 the presence of a deep lead in Mount Franklin was established. Deep lead mining was initially unsuccessful, and it was not until the late 1870s that the Franklinford Gold Mining Company mined at Mount Franklin on a significant scale. A few years later the Mount Franklin Estate Gold Mining Company also struck gold, followed by the Shakespeare and Great Western companies in the mid-1880s. By the late 1880s, however, deep lead mining had ceased in the area. Soon after gold was discovered in 1851, Victoria’s Governor La Trobe wrote to the Colonial Office in London, urging ‘the propriety of selecting and appointing as Mineral Surveyor for this Colony a gentleman possessed of the requisite qualifications and acquaintance with geological science and phenomena’. Alfred Selwyn was appointed geological surveyor in Australia in 1852 which began the Geological Survey of Victoria. In 1853-69 the Geological Survey issued under Selwyn's direction sixty-one geological maps and numerous reports; they were of such high standard that a writer in the Quarterly Journal of the Geological Society of London bracketed the survey with that of the United States of America as the best in the world. During his years spent in Australia, Selwyn collected numerous significant geological specimens, examples of which are held in collections such as the Burke Museum.This geological specimen is an example of basalt and olivine which shows the volcanic lava activity and geographical specific nature of Mt Franklin as a significant volcanic site. According to Agriculture Victoria 'The crater is one of the deepest in the Central Highlands area. It is a major megacryst site with some of the largest known Victorian examples of megacrysts of augite and an orthoclase. The small parasitic mound of Lady Franklin on the western flanks adds to the geological interest of the site'. This specimen also highlights the locality as a significant place for both indigenous activity and Victorian gold rush era mining practices.

Although it is not known where these specimens were collected, Victoria and other regions of Australia were surveyed for sites of potential mineral wealth throughout the 19th Century. The identification of sites containing valuable commodities such as gold, iron ore and gemstones in a locality had the potential to shape the development and history of communities and industries in the area. The discovery of gold in Victoria, for instance, had a significant influence on the development of the area now known as 'the goldfields', including Beechworth; the city of Melbourne and Victoria as a whole. Agate occurs when amygdales (gas pockets) form in the upper levels of basaltic lava flows. If these pockets or bubbles are iniltrated by water bearing silica in solution, the fluid dries and hardens in layers, forming round or egg shaped nodules or geodes within the rocky matrix. Agate is formed of a silica mineral chalcedony similar to quartz. The term carnelian primarily refers to the reddish shading of the stone; whether the stone is termed an agate or chalcedony type is often influenced by the degree of colour banding the specimen shows. The specimens are significant as examples of surveying activity undertaken to assess and direct the development of the mineral resource industries in Victoria and Australia, as well as the movement to expand human knowledge of earth sciences such as mineralogy and geology in the nineteenth century.Three small geological specimens that appear visually consistent with images of rough or unpolished Carnelian Agate or Chalcedony. geological specimen, geology, geology collection, burke museum, beechworth, indigo shire, north-east victoria, gemstones, agate, carnelian

Dolomite is a mineral, calcium magnesium carbonate, with the chemical formula CaMg(CO3)2. It is a principle component of various rock types sometimes also referred to as dolomite, including dolostone, dolomitic marble and dolomitic limestone (according to the composition of each type). Dolomite rock is found in sedimentary basins throughout the world, comprising approximately 2% of the Earth's crust. It is formed when lime mud or limestone encounters groundwater containing magnesium. Dolomite can contain elements such as lead, zinc and copper. Dolomite and limestone are used in various construction, landscaping and agricultural processes. This specimen was donated to the Burke Museum in 1868 by Alfred Selwyn as part of the Geological Survey of Victoria. It was donated to the Museum in 1868. Victoria and other regions of Australia were surveyed for sites of potential mineral wealth throughout the 19th Century. The identification of sites containing valuable commodities such as gold, iron ore and gemstones in a locality had the potential to shape the development and history of communities and industries in the area. The discovery of gold in Victoria, for instance, had a significant influence on the development of the area now known as 'the goldfields', including Beechworth; the city of Melbourne and Victoria as a whole. Dolomite and limestone are mined at several locations in Victoria, including sites in the North-East of the state in Bindi and Limestone Creek. There are notable dolomite deposits in most Australian states. The dolomitised form of the mineral tends to come from older limestone deposits, formed during the palaeozoic era in marine settings, so this specimen may have come from a deposit located along a coastline in Victoria or another state. The specimen is significant as an example of surveying activity undertaken to assess and direct the development of the mineral resource industries in Victoria and Australia, as well as the movement to expand human knowledge of earth sciences such as mineralogy and geology in the nineteenth century.

Dendrites are deposits of black minerals, typically manganese oxides that precipitated from water seeping through fractures in fine-grain rocks like a sandstone or limestone. Dendrites are much less regular than plant fossils and lacks vein structures. The manganese cryztallizes through the process called 'supercooling'. Some samples of dendrites occur in volcanic rocks in the Lilydale district, east of Melbourne. Sandstones are made of tiny sand grains that may have been deposited in the sea and later formed together. Most sandstones are made of quartz which are chemically-resistant minerals. This particular specimen was donated by Alfred Selwyn in 1868 as part of the Geological Survey of Victoria. It is connected to the original 1875 catalogue on Geological Specimen with number 189 'Quartz Crystals_Quartz Crystals (two are polished)'Dendrites on sandstones This specimen is an important contribution to the geological history of Victoria, as well as its links to the 1868 Geological Survey of Victoria.

A large percentage of these specimens were collection as part of the Geological Survey of Victoria 1852-1974. The Geological Survey of Victoria was an organisation founded in response to the Victorian gold rush to explore the geological and mineral resources and to record a detailed map of the state. It was headed by British geologist, Alfred Richard Cecil Selwyn (1824-1902), who was responsible for issuing over 60 geological maps during his 17 years as director. These maps were all hand-drawn and coloured and became the benchmark for accuracy for geological mapping. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth.

Galena occurs in a range of deposit contexts, often in metalliferous veins, such as Broken Hill, Australia; Coeur d’Alene, Idaho, United States.; Clausthal Zellerfeld, Germany; and Cornwall, England. Large deposits also replace limestone, dolomite, or occasionally organic matter, or have a contact-metamorphic origin. Galena is additionally found in cavities, brecciated (fractured) zones in limestone and chert, and in coal beds. This specimen was recovered from Broken Hill NSW and is 60% lead with 8-12 oz/silver to the ton.Galena or 'lead glance' is a grey lead sulfide and the chief ore mineral of lead. It forms isometric crystals in which the ionic lattice is similar to sodium chloride. Galena is brittle and easily weathers to secondary lead minerals, with the upper part of mineral deposits often containing cerussite, anglesite, and pyromorphite. It usually contains silver, which is mined along with its lead content. Other commercially important minerals that form in close association with galena are antimony, copper, and zinc. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Native Sulphur in its solid form is a yellow crystalline mineral that forms near volcanic vents and fumaroles where it is the solid form of hot gases. It is also frequently found in the subsurface as a by-product of sulphide ore mineralization. In all its forms, sulphur is one of the most commonly occurring minerals on the planet, especially in natural gases, and is key to the make-up of a range of other minerals. It is essential to continuing life on earth, and was used in ancient societies as part of medical care, religious rites, and entertainment, and was key to the invention of gunpowder by the Chinese.

The exact site of extraction for this specimen is unknown, but it was probably collected in New Zealand in the 1850s. Sulphur is significant both for its historical and current uses, and for its nature as one of the most abundant minerals on the planet. Sulphur's importance comes both from its abundance and its role in ensuring survival, creating other minerals, and daily human life.

It is not known where this opal originated. Common Opal is formed from silica-rich water entering the earths crust and hardening into a gel of water and silica-spheres, layered through the specimen. Common opal differs from precious opal in colouration and appearance, with precious opal including more colours, and having a translucent or glossy appearance, where common opal shows less colour and is typically opaque. It scores high on the Mohs hardness scale, and is common throughout the world, especially in Australia, where it is far more prevalent than the highly-prized precious opal. Australia is also the highest producer of opals in the modern world.

A granular metamorphic rock, marble is derived from limestone or dolomite and composed of calcite or dolomite interlocking grains. Heat and pressure from overlying sediments form it from limestone buried deep in Earth's crust. Graphite, pyrite, quartz, mica, and iron oxides can affect rock texture and colour. This specimen was found in Carrara, Italy. Carrara marble is the most common marble found in Italy, and it gets its name from the region where it is located. The marble was also called Luna marble and was used as a decorative element in buildings and sculptures. It has been quarried since Roman times in the Lunigiana, the northernmost tip of Tuscany, just outside the city of Carrara in the province of Massa and Carrara.Marble is one of the most popular and expensive rocks used in sculpture, architecture, interior decorations, statues, table tops, and novelties. It is available in various colors and textures depending on the chemical composition. The strength of the rock and its ability to hold finer details have made it a favorite among designers. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880.

Fluorite comes in a variety of natural colours and crystal formations and glows under ultraviolet light (the word 'fluorescence' comes from the same etymological source). In its pure form, calcium fluoride, it is a colourless combination of the elements calcium and fluorine, but gains its colour from trace elements that infiltrate or replace calcium within its crystal structure during its formation. Although fluorite crystals polish well and can achieve a high level of lustre, the mineral is very soft (4 on MOHS hardness scale) so it is unsuitable for use in rings and must be handled and stored carefully if used in other forms of jewellery. Most crystals of the mineral are too coarse for decorative purposes but have been mined under the name fluorspar for a variety of commercial and industrial purposes. These include the production of hydrofluoric acid, smelting metal alloys, producing glazes and ceramic finishes and use in medical and dental products. An existing label for this specimen indicates that its origin or collection-point was 'probably USA.' Fluorspar, the form of fluorite used commercially and industrially, was mined in significant quantities in the counties of Hardin and Pope in South-Eastern Illinois throughout the Nineteenth and Twentieth Centuries. Fluorite was made Illinois' state mineral in recognition of its contribution to the state's identity and economy. The specimens are significant as examples of surveying activity undertaken to assess and direct the development of the mineral resource industries, as well as the movement to expand human knowledge of earth sciences such as mineralogy and geology in the nineteenth century.The specimen is a piece of purple shaded fluorite (also known as fluorspar), the mineral form of calcium fluoride.
