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. This specimen is part of larger collection of significant geological specimens in the Burke Museum that was collected from around the world between 1868-1880. 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. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.

Brown Coal is typically found as rocks. During formation the Brown Coal starts as peats, which is an acidic brown deposit resembling soil, and over time when subjected to pressure and heat these peats form the Coal. Brown Coal is the lowest rank of coal as it has a low carbon (energy) content, and a high moisture content. This high moisture content makes Brown Coal unsuitable for overseas exports. This particular specimen was recovered from the Yallourn Mine in Latrobe Valley, Victoria as part of the geological survey of Victoria being carried out by Alfred Selwyn. Otherwise known as the 'Yallourn Power Station', the Yallourn Mine is Australia's second largest mine. Yallourn Mine was first built in 1920, and since then it has been providing over 1 billion tonnes of Brown Coal to Australia every year. The Yallourn Mine is responsible for 22% of Victoria's electricity and 8% of Australia's electricity. As of 2021 the mine employs around 500 people. Due to ongoing maintenance issues and Australia's move to cleaner energy, the Yallourn Mine intends to shut down permanently as of 2028. 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.Brown coal is considered to be an essential rock to Australia's energy consumption. Although plentiful in sources, Brown Coal is not able to be exported overseas due to its high moisture content. As Australia moves towards cleaner energy, Brown Coal is going become less used. 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.

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. 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.

Ventifacts are sand-blasted rocks that are typically faceted and often display parallel grooves carved by wind-blown sand. They are useful indicators of wind direction and strength in environments such as deserts, mountains, and coastal areas because they are usually not hidden by later sediment, soil or vegetation cover. In Antarctica ventifaction is strongly related to the composition or type of rock. Ventifacts are important because they provide evidence for abraders such as sand, dust or snow and ice crystals, and offer a unique understanding of past wind processes that are effective in the reconstruction of past wind flow conditions and can provides clues to weather and climate changes in the past. Interestingly ventifacts have also been found on the surface of Mars. They were a threat to the NASA rover due to the sharp angles of the facets, created by the Martian wind over the course of millions of years. These Martian ventifacts act like weathervanes for past wind and weather patterns on the red planet in a similar manner to those found on earth.The Geological Survey of Victoria was instigated in response to the Victorian Gold Rush which began around 1851 in the Beechworth, Castlemaine, Daylesford, Bendigo and Ballarat areas. The survey was conducted by Alfred Richard Cecil Selwyn from his arrival in December 1852 until his resignation in 1869and during this time he trained many notable geologists, e.g. Aplin, Wilkinson, Daintree, who went on to other State survey senior positions.

Actinolite is usually found in metamorphic rocks, such as contact aureoles surrounding cooled intrusive igneous rocks. It also occurs as a product of the metamorphism of magnesium-rich limestones. Pyrite is usually found with other sulfides or oxides in quartz veins, sedimentary rock, and metamorphic rock, as well coal beds, and as a replacement mineral in fossils. Actinolite is an amphibole silicate mineral. It is named after the Greek word "aktinos" meaning “ray” in allusion to the mineral's fibrous nature. Fibrous actinolite is a type of asbestos and was once mined along Jones Creek at Gundagai, New South Wales. Pyrite or "Fool's Gold" is the most common sulfide mineral. It is named after the Greek "pyr" meaning "fire" because it can be used to create sparks needed for a fire if struck against metal or a hard surface. Due to its gold colour, pyrite can be mistaken for gold and often forms alongside it, causing small amounts of gold to be present in rocks containing pyrite. Most importantly, pyrite is an ore of gold. Pyrite is sometimes used as a gemstone but is not great for jewellery as it easily tarnishes. In some fossils of ammonites – shelled cephalopods that died ~66 million years ago – pyrite also replaces the shell. 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.

Malachite is a water soluble, crystalline, triphenyl methylene chloride salt. It has a close relationship to copper because it is common for Malachite and copper to come from the same ore. Malachite often has shades of green, making it also known as Malachite Green. As a result of it's colour, it is known for being a dye and has been used in the dye industry, the textile industry and in medical fields. Cobar in New South Wales is well known for it's mining. This is because of the number of important deposits present in the area and include three important mining belts where most of the materials are found. These are the 'Cobar belt', the 'Canbelego belt' and the 'Girilambone belt'. The 'Cobar belt' runs underneath the main town. Copper was first discovered in Cobar in 1869 and since then, many deposits of other materials have been found, including Malachite.This specimen is significant because it comes from Cobar, NSW and represents the many deposits of materials found there. Cobar has a long history of mining and is a source of Australia's copper minerals. Malachite is often found in copper deposits meaning that it is representative of Cobar's copper production. Malachite is known for it's vivid green colour and as a result, has many uses, such as meaning used as a dye. This makes it a valuable material and highly significant.

This particular specimen is found in Wolgan Valley, New South Wales. It could be linked to the abandoned oil shale mining sites in Wolgan Valley such as Newnes. Newnes was an industrial complex operational in the early 20th century is now partly surrounded by Wollemi National Park. It produced motor spirit, kerosene, and gas oil. Newnes's Torbanite oil shale rock contained around 350 litres of oil shale per tonne. The Torbanite was mined by the Commonwealth Oil Corporation Ltd. Oil shale is a sedimentary rock and also a form of fossil fuel. It is often formed millions of years ago and usually contain fossilised remains of plants and/or animals. Oil shale is rich in kerogen that releases hydrocarbon when heated. These hydrocarbon can be used as an alternative petroleum or natural gas. The oil-shale rock was converted into oil by "destructive distillation"; the rock being heated until it broke down to form an oily vapour and an ash residue. Oil bearing shale is one of Australia's national assets. There are many oil companies established in Australia. It reflects Australia's rich natural resources as well as connection to the Australia's engineering and oil industry. The booming oil shale extraction businesses can be traced as far back as 1920s. 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.

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.

Anthracite typically occurs in geologically deformed areas due to extreme heating – with temperatures ranging from 170 to 250 °C – caused by igneous intrusions or high geothermal gradients. It is most commonly found in northeastern Pennsylvania in the United States; however, smaller amounts are also found in Australia, China, eastern Ukraine, South Africa, western Canada, and other countries. This specimen was recovered from Tasmania and is 85-95% carbon.Anthracite is the mineral name for hard coal and is the least plentiful of all coal types. It is clean to the touch and, when polished, is used for decorative purposes. Before natural gas and electricity, anthracite was used for domestic heating as it produces little dust, burns slowly, and gives off a minor amount of smoke. However, it is also limited in abundance and expensive. 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 was donated in 1868 by Alfred Selwyn. Olivine is typically found in basic and ultra-basic igneous rocks around the world, in a variety of colours including yellowish green, olive green, greenish black and reddish brown with a transparent to translucent diaphaneity. The luster of the specimen is vitreous, the luminescence non-fluorescent and when fractured the mineral is very brittle producing small, conchoidal fragments. Chromian diopside is normally found in small sizes as the larger the size of the mineral the darker the colour is, almost black rather than green. Chromium is the element that gives chromian diopside and emeralds their rich green colour. Diopside is found across the world in multiple colours however gem-quality chromian diopside is mined in Siberia, Russia and prominent within the jewellery industry as a more affordable substitute to emeralds. Chromium-bearing diopside has been located across Australia. Chromium-bearing Diopside is located across the world found in North America, parts of South America, and across Australia, Africa, Europe and Asia. Chromium-bearing Diopside is mined in Siberia, Russia and is sold as a commercial substitute for emeralds. The stone is often turned into jewellery. This item is one of many geological and mineral specimens that constitute a broader collection obtained from various regions across Australia (as well as some international locales) and generously contributed to the Burke Museum between 1868 and 1880. A significant portion of these specimens originated from Victoria and were acquired as a result of the Geological Survey of Victoria, initiated in 1852 during the Gold Rush era. The primary objective of this survey was to investigate and chart the geological characteristics of Victoria. The procurement of geological specimens played a vital role in advancing our comprehension of the Earth's scientific composition and was instrumental in supporting research and educational institutions throughout Australia, including the Burke Museum, in their efforts to foster further exploration and study.

Coorongite is a dark, rubber-like, highly resilient structureless algal deposit. In the Coorong district of South Australia it occurs in moderate quantities associated with the coastal swamps and sand dunes which extend for a considerable distance east of the mouth of the Murray. This particular specimen was recovered from the south of the Coorong River, South Australia. A type of sediment rich in organic matter, Coorongite is the unlithified end-member of the sapropelic coal series. The members of the sapropelic coal series can be ranked in order as sapropel (the unlithified form), sapropelic-lignite, and sapropelic-coal (the lithified forms) based on increasing carbon content and decreasing volatile content. Sapropel (Coorongite) is an unlithified dark, pulpy, fine organic mud containing concentrations of algae and miospores that are more or less identifiable. Coorongite is typically found as an algae like substance, that can be found in irregular size pieces. Coorongite was believed to be dried up oil due to its rubber-like texture. The Coorongite is also soft to the point where it can be cut into with a knife or it can be broken and torn by hand. Otherwise known as 'Kurangk', the Coorong River is home to the Ngarrindjeri people, which acts as both a place for gathering food and a spiritual place. In 1852 the first sight of Coorongite was found along the Coorong River. The finders mistook the Coorongite for dried up oil, which lead to the belief that there were oil reserves under the Coorong River. Between the 1860s and the 1930s the Coorong River became a place where mining oil and Coorongite became precedent. Nowadays, the local council and the South Australian Government are working together with the Ngarrindjeri people to sustain and preserve the Coorong River and the culture that is with it. 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. Selwyn went on to collect geological samples and catalogue thousands of specimens around Australia. 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.Coorongite is considered to be a mineral with a unique texture, where it can be both hard and soft. Coorongite can also be considered to be a rare mineral, as it is only located along the Coorong River and due to the mining of it, has left very few sources. It was believed at one point that Coorongite could be used to replace oil. 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 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’.

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.

This specimen is Cassiterite in Quartz. Cassiterite is a tin oxide metal that forms in thin crystals which can have a beautiful lustre. Quartz is made of silicon dioxide, also known as silica, and is one of the most common minerals on earth. Cassiterite has been a fundamental source of tin ore for humans throughout history, including today. Tin is an important metal that has a wide variety of human uses in different areas, from dying fabric, to making mirrors, and their most well-known use ‘tin’ cans. Tin cans are primarily made of steel and are coated with tin in order to take advantage of tin’s property of being non-corroding. This is a massive step in the history of food preservation. Tinned food first reached Australia in 1815 with early settlers, and it began to be manufactured here in the 1840s. It was incredibly popular, and was a highly exported product, which would be a contributing factor to the ‘tin mining boom’ of the early 1880s. This specimen was collected at Jingellic, New South Wales, in about 1852. Although the Goldfields of the 1800s are much more well-known, tin mines existed alongside the gold mines which began in the mid 19th century and extended almost one hundred years, to the mid 20th century. Specimens like this would have been used as evidence to justify tin mining operations in the region as an investment.

A fist-sized solid geological specimen made on one half of tin oxide, which is dark grey, and on the other side of silica, which is brown and cream.burke museum, beechworth, geological, geological specimen

In 1905 Richard Squire was manager of the West Berry Consols at Allendale, and developed an improved system of mine ventilation, which was supported in "The Age."[4] He was successful in combating and remedying the gas and ventilation troubles of the Deep Mines of Creswick and Allendale Districts after all had failed. MINE MANAGERS’ ASSOCIATION. Ballarat Branch. ... Mr R. B. Squire, manager of the West Berry Consols, at Allendale, submitted a paper detailing what he had done tor the betterment of ventilation in the alluvial mines of Smeaton and Mary borough districts- Members gave Mr Squire every credit for the results that he claimed to have effected; the adoption of his ideas had testified to their value to mine-owners. It was painted out, however, that for want of a thorough debate of the subject with experienced men the author had unwittingly included some general statements that required modifying in some points and extending in others, in justice to other workers among the earlier and the present day managers of mines. It was decided to invite the author to meet a sub-committee on this subject!A variety of Letters written by Richard Squire to his son Tom Squire about the goings on at Mt Mercer Mine 1937richard squire, tom squire, hazel squire, jack squire, jim squire, ned, mt mercer, plant, skids, pump, poppet, carburetor, shaft, balance weight, pulleys, syndicate, suction, lease, reports, estimates, flat fields, reef, trucks, pipeclay, sandstone, suction pipe, valves, honeycomb rock, yarrowee, ballarat, reef combs, cheques, yellow slate, leigh river, dyke, quartz, ballarat deep leads, ballarat deep leads extension, bore, reads, bedrock, cemented sand, g m of a, gold mines of australia, liz the car, geoff squire, lode, cameron and sutherland, hayes timber, alan squire, ethel, ross creek field, ross creek gold mining co., frank herman, lillas, jack hayes, eyres brothers, g.gay & co, buninyong, glenfine, the star mine of avoca fields, talbot alluvials, guildford plateau, a.b.c. special supply store, geological branch, shell coy, lawaluk, almanac, mcbinny, bingley's paddock, cargaire valley and lead, stand and deliver demands, sheehan's, smeaton hotel, john charleson, aleck charleson, ted brown, billy jordan, mr banks, ballarat main lead, binney, goon, illabrook, mrs trenery, bre, max, june, mary, len, barry, hunter, herman, martin, aunt annie, bella, pitfield coy, mcnaughtons, donaldson, dereel, hogan, the bay leads, avoca field, ballarat alluvials, neil cameron, haddon field, courier, tom cotton, llewellen, stanley hunter, mr leonard, tom mitchell, school of mines, bryant, a.c. connely, dodson, constable mcmullins, adam ronaldson, bewick mining & co., reginald murray, r.c. selwyn, craig's hotel, broken hill syndicate, morrison's lead, wilkinson, j. hayes, mr nichol, burglary, baragwanath, wilkinson ross, creswick, seville, mr. ross, o'connor, c. mcgrath, alfred mica smith, henderson ross, angus kelly, a. r. dodson, duke of wellington plant, the moorabool lead, williams, paralysis, woodlock, squire, whipp, joe williams, peacock, moran, buchanan, hoare, bree kutchel, kohinoor band and alluvian, star of the east, bonshaw, epidemic, polio, mining
