New Zealand Greenstone, also called Pounamu is found on New Zealand’s South Island in riverbeds and boulders, and colours vary depending on the source, but always include green tones. It is a form of the mineral nephrite, also known as jade, and is a tough stone with a crystalline structure, made up of calcium magnesium and iron silicate. Its hardness means it is ideal for carving, and has been used for this purpose throughout history, especially by the Maori people of New Zealand. Greenstone features heavily in Maori mythology, and the traditional name for the South Island, Te-Wai-Pounamu, literally translates to waters of greenstone. Wearing of Greenstone pendants with different carvings is practiced by Maori to represent connection to land and ancestors, or to endow the wearer with certain attributes. The sticker on the base of the specimen identifies it as a product of Hokitika Jade Company. The company, which was active in the 1970s, sold jade and greenstone specimens and ornaments. Hokitika, which started life as an 1860s gold rush town, is the origin of most nephrite found in New Zealand, and the centre of the Greenstone carving industry. The object has scientific and research potential as part of the Burke Museum's Geology Collection, and as and example of New Zealand Greenstone. It also has spiritual significance for it's role in Maori beliefs and communities, where it is both traditionally worn and features in mythology. As a valuable stone regularly used in carving and jewellery, it has aesthetic significance. Sticker on base: "N.Z.

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. 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, silica-based mineral specimen of Common Opal in shades of grey, green, and yellow, with a thick grey vein running through the centre. geological specimen, geology, geology collection, burke museum, beechworth, opal, common opal, gemstone, mining

Selwynite is a fine-grained, compact green rock made primarily of chromian muscovite (fuchsite) and diaspore. Corundum and fuchsite can occur together in the form of massive aggregates or nodules. Often, copper carbonates are found as earthy films or tiny crystals in joint planes. The mineral name honours the late A. R. C. Selwyn, founding Director of the Geological Survey of Victoria. The particular specimen, a mottled green stone suitable for carving was recovered and found in Heathcote, Victoria, Australia. The rarity and qualities of this mineral attracted commercial mining, which was not successful, but traces of the mine shafts still exist today, and it is still highly valued by mineral collectors.Selwynit is considered to be one of the rare forms of rock because it is composed of phosphate minerals containing zirconium. This is an extremely rare combination found in nature. 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 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.

Bituminous coal is the most common type of coal, abundantly found in ancient coal deposits which can be dated back millions of years. Often referred to as soft or black coal, this specimen exhibits a high carbon content, ranging from 76-86%. It also holds a relatively high energy density (27 MJ/kg) meaning that it releases significant amounts of energy when burned. Bituminous coal is most commonly used for electricity generation, as well as in the production of steel. This particular piece of coal was collected as part of the Geological Survey of Victoria in the nineteenth century. It originates from Cape Paterson, a seaside village located in South Gippsland, Victoria (located on Bunurong Country). The discovery of bituminous coal in this locality was first made in 1826 by explorer William Hovell. More discoveries were gradually made over the following decades and in 1859 the Victorian Coal Company commenced the first active coal mining operations in the state by sinking a number of shafts and bores near the area of Cape Paterson. Evidence of this coal-focused past can be found today at the State Coal Mine Museum in the nearby town of Wonthaggi. This specimen is significant as it was collected from the locality of Cape Paterson in Victoria, an area that has since become historically instrumental in the mining of coal and other substances in the state of Victoria. 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 copper carbonate hydroxide mineral. It has a chemical composition of Cu2(CO3)(OH)2. It often forms within limestone where a subsurface chemical environment favourable for the formation of carbonate minerals can occur. It is a substance that can be found in many different parts of the world including: Australia, USA, Russia and the Democratic Republic of Congo. Malachite has historically been used to produce copper, with mining of the mineral dating back over a period of four thousand years. Due to its beautiful green colourations, it is also commonly used for aesthetic purposes such as in the production of sculptures and jewellery. This particular specimen was collected from the town of Burra, South Australia as part of a geological survey undertaken during the nineteenth century. The locality (located on Ngadjuri Country) has a long history of mining, particularly in copper mining, as the area is rich in copper deposits. The first significant discovery of this was made in Burra (Burra Burra Mine) in 1845 and, at the time, the mine was the largest and richest of its kind in the world, producing nearly five percent of the total world copper output. This specimen is significant as it is considered to be a rare gemstone, as many of the original deposits for the stones are significantly depleted, leaving behind very few sources. 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.

Laterite refers to both a rock and a soil type that is rich in clay, as well as Iron and Aluminium. It is created during a process that is called laterization, where high heat and seasonal heavy rainfall cause there to be wet and dry periods, which over time hardens the soil into rock. Because of this, most laterite is formed between tropics of Cancer and Capricorn. The iron oxide in laterite is what gives it it’s orange-red colouring. The largest religious complex in the world, Angkor Wat in Cambodia, is partially constructed of laterite, particularly its foundations, as laterite is porous and allows rainwater to drain. This specimen of laterite was collected from the Democratic Republic of Congo while it was colonised by Belgium in the 19th century. Laterite forms in many parts of the world, particularly between the tropics. It is used both for ore and as a building material, and comparing specimens from different parts of the world allows us to document the different compositions that this mineral can have when formed at different locations. 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.

Montmorillonite is a type of clay composed of aluminium silicate that forms very small particles that are not well-bonded to one another. This is why it is so soft. When in the presence of water, all types of clay swell. Montmorillonite swells even more than most types of clay, which is why it is often chosen over other types of clay in its practical uses. Montmorillonite has many different practical uses, including in the mining industry, as a soil additive, as a sealant, as a desiccant to draw water out of the air, to clean ponds, to make kitty litter and in cosmetics. Montmorillonite is a common mineral and, despite being named after Montmorillon, France, can be found all over the world, including many deposits in Australia. It is not known where this particular specimen originates from. Montmorillonite is an economically and socially significant material with a wide variety of uses. Having samples of common and important minerals allows collections, like the Burke Museum, to have a more complete view of the land on which they are located, and therefore a more complete view of heritage. 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.

There are 17 opal fields in Australia. This opal bearing stone was found in Lightning Ridge, NSW over what is known as the Great Australian Basin. This basin was formed and covers an area of 1.7 million square kilometers in eastern Australia in the Cretaceous period. This basin used to contain an inland sea, which provided an environment where silcrete eventually formed when water levels changed. This eventually seeped into other structures, and eventually hardened and formed opal. Lightning Ridge has a population of around 2000 people, with about 80 000 visitors every year. It is a historic mining town, and is known for its deposits of a rare black opal. Mining started in the area in the late 1800s, early 1900s when the black opal was discovered. This opal-bearing stone is of social and historical significance. It is from Lightning Ridge, which is well-known for being a large producer of opal stones, most famously black opal. The history of the period dates back to 140 million years, with the discovery of black opal in the early 1900s causing interest in the area. 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.

It is made up of andalusite. Andalusite is a rock-forming mineral, sometimes found in granite or schist. It is often used to make glass, ceramic products, chemicals, and heat-resistant bricks as it can withstand high temperatures without changing. The chiastolite contains particles of graphite, which arranges in geometric patterns. When crystal growth occurs in the rock, the granite particles concentrate at crystal interfaces and can result in cross shapes. These ‘cross stones’ have been valued and used for their spiritual or religious meaning and used as charms, gems, or amulets. Chiastolite was first discovered in 1754, seen in a description in a published book by a palaeontologist, Franciscan priest, and Spanish author, Jose Torrubia. Deposits have been found in Australia, France, the USA, Chile, Canada, Spain, Brazil, Sri Lanka, and Russia. Deposits have been found in Western Australia and South Australia. This particular specimen was found in Bimbowrie, South Australia. Other chiastolite specimens have been found in Bimbowrie, along with jasper, quartz, and aventurine in the form of rolled pebbles or schist. This chiastolite specimen is socially and historically significant. It is a very rare sort of andalusite mineral. It is from one of only two locations where it is regularly found in Australia. The carbon cross has made it an important religious symbol in the past. Its ability to withstand high temperatures has made it a common ingredient in heat-resistant bricks and ceramics today.

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.

Olivine is mostly found on the Earth's surface in igneous rocks that are dark-coloured. It is common at divergent plate boundaries and at warm spots, such as volcanic areas. It crystalises and forms during the cooling of magma. Olivine is used in refractory sand, bricks, and gemstones. Olivine has been found on a number of meteorites, which might have originated from large asteroids or the mantle of a now-destroyed planet. This olivine crystal is thought to originate from Mount Noorat, with speculation that it could have originated from Mount Shadwell. Mount Noorat is a dormant volcano cone located in the Newer Volcanics Province of Victoria. Mount Noorat belongs to the Kirrae Wuurong people, who used the Mount as a place for meetings and gatherings prior to European settlement. Contact was first made between European settlers and the Indigenous people in 1841. The Mount has mostly been used for cattle and sheep grazing. Mount Shadwell is a well-known source of olivine and is the highest of a gathering of volcanic cones. The New Volcanic Province is located in South East Australia and covers 15000 square kilometres. It contains 400 explosive vents and small shield volcanoes. The last eruption is thought to have occurred 5000 years ago at Mount Gambier and Mount Schank. This olivine crystal has been identified as a volcanic bomb, which is a molten rock which was pushed out and ejected into the air when a volcano reupts. A rock needs to be larger than 65 mm in diameter to be classified as a volcanic bomb. This olivine volcanic bomb and its locality is historically and socially significant. The olivine was found in the Newer Volcanic Province, an area which contains over 400 dormant volcanoes. This olivine is one part of a volcanic bomb, which would have ejected when magma erupted out of a volcano. 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.

Thunderegg Agates are formed within rhyolite volcanic ash layers. They are rough spherical shapes, varying in size from less than an inch to over a metre long. Thundereggs usually contain centres of chalcedony which may have been fractured followed by deposition of agate, jasper or opal, either uniquely or in combination. A unique characteristic that these specimens have is the fact that they often look like ordinary rocks on the outside, but slicing them in half and polishing them may reveal intricate patterns and colours. These particular specimens are examples of thunderegg agates. Agate is a variety of chalcedony, a cryptocrystalline form of quartz. The agate component contributes to the intriguing internal patterns of the specimens. The specific locality of these specimens is unknown but they can be found in flows of rhyolite lava. They are formed in gas pockets in the lava, which act as moulds. These specimens can be found globally, with specific locations in Germany being particularly abundant.

A fossil refers to any remains or traces of past life that are preserved in the rock. It could be remains of plants or animals. Fossil leaves are commonly found on different types of rocks. These fossils can go as far back as the Triassic Age just like the series of fossil plants collected at Denmark Hill, Ipswich in Queensland. Fossils leaves are formed when dead plants get buried by sediments like mud, sand, or volcanic ash. Often, it gets detached cleanly from stems along a special layer of weak cells, then twigs, and, less commonly, cones of conifers and fruits and seeds of flowering plants. Over time, the leaves or pieces of leaves get buried by more sediments and eventually gets 'lithified' or hardened into a rock. Erosions and mining can cause the rocks to break and reveal the fossils buried in it. Fossilisation frequently takes place at sites in the lowlands where deposits of clay, silt, sand are found. This is usually due to weathering and erosion of rocks. Fossil leaves can provide information about ancient Australia's way of living. It contributes to Victorian biodiversity records and its botanical collections. It also contributes information on the geographical profile of Victoria as fossilisation usually occur at estuaries and deltas of rivers, river flood plains, ponds and lakes. 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.

Galena is the natural compound of lead and classed as a sulphide, it crystallises in a cubic pattern and its chemical formula is PbS. Galena is a primary source of both lead and silver. This specimen of Galena comes from Broken Hill. Broken Hill has one of the world’s largest and most significant deposit of ore for the production of lead. Mining of Galena at Broken Hill began with the staking of land by Charles Rasp in 1883. By the following year, in 1884, Rasp and six others had formed Broken Hill Mining Company. Broken Hill Mining Company eventually evolved into BHP group limited and is currently the largest mining company in the world and the largest company in Australia. There is archaeological evidence from artefacts discovered in Turkey that humans have been extracting lead from galena by the process of smelting since at least 6500 BCE. This specimen also has quartz on the top surface which is frequently discovered alongside Galena. This mineral specimen is of historic significance as a sample of Galena extracted from Broken Hill during the 19th century. Mining for Galena in Broken Hill begin in 1883 by Charles Rasp and evolved into the world’s largest mining company – BHP Group Limited. Broken Hill is one of the world’s most significant deposits of ore for the production of lead. 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 flat, hand-sized, grey sulphide specimen that is the natural compound of lead with a quartz formation on the top surface.

Sphalerite or sphaelerite is named from the Greek word for 'treacherous' or 'deceiver' as specimens can vary widely in appearance, making them hard to visually identify. It is a zinc sulfide with the chemical composition (Zn,Fe)S, the most important ore of zinc. Specimens of sphalerite can contain iron as a substitute for up to 25% of the usual zinc present, as well as trace elements of gallium, cadmium, geranium and indium. Small amounts of arsenic and manganese may also be detected. Sphalerite is found in igneous, sedimentary and metamorphic rocks. It forms when carbonate rock encounters acidic, zinc-bearing fluid. It often forms in veins or in fissures of the existing rock, with colours and crystal shapes dependent on the composition of the the combining elements. It forms isometric crystal shapes including cubes, tetrahedrons, octahedrons, dodecahedrons. This specimen was collected in approximately 1852, in Broken Hill, NSW, as an adjunct to 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.The specimen is significant as an 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.A pipe-shaped specimen of sulfide-mineral zinc ore displaying patches of black, brown, beige and gold colouring.

William Baragwanath joined the Victorian Department of Mines in 1897, was director of the geological survey (1922-4), Chief Mining Surveyor (1924-43), Secretary for Mines (1932-34), consultant to the Department of Mines (1943-50) . He was born at Durham Lead on 1 August 1878 and was a former student of the Ballarat School of Mines. Baragwanath was president of the Royal society of Victoria (1943-44) and a councillor of the Ballarat School of Mines (1916-1950). After Baragwanath's death on 20 September 1966 the Department of Minerals and Energy (Geological Survey division) donated a number of Baragwanath's items to the Ballarat School of Mines, including this collection.

This large, leather bound journal was made for the Public Library and Burke Museum in Beechworth by book manufacturer, William Detmold in 1875. It was commissioned by the President of the Library and Burke Museum committee, Dr Antoine Mousse, for the purpose of cataloguing all the items in the collection. The cataloguer was the curator at that time, William Morton, whose hand-writing appears in the journal today. When William Morton first started recording in this journal in 1875, there were already a number of existing items in the institution. The Public Library and Burke Museum in Beechworth had actually been operating since the 1850s; first as a Young Men’s Association in 1856, then as Beechworth Athenaeum in 1858, then as the Beechworth Public Library in 1860. Then in 1861 when news of the death of Beechworth’s former police superintended, Robert O’Hara Burke, reached the town, it was agreed that the Public Library would also become a museum to tribute his legacy, renaming it as the ‘Public Library and Robert O’Hara Burke Memorial Museum, Beechworth’. Many of the items from the early institutions would have been used to form the nucleus of this new organisation. Plus, the additional items that were either collected or donated to develop it into a museum. The catalogue is extensive. There are exactly 461 pages of recorded items, each page detailing the various collections the museum acquired in the late 19th century. Collections recorded in this catalogue include a large collection of geological specimens, that were given to the museum in 1868 by the Geological Survey Department of Victoria. A large collection of taxidermy mounts, that were given to the museum as skins by the Museum of Australia in 1865. An extensive collection of Aboriginal artefacts that were purchased from amateur anthropologist R. E . Johns in 1868. As well as artworks, charts, photographs, machinery, maps etc., all of which have been held in the museum since. This catalogue also details the governance and management of the organisation. There were originally 30 rules that governed the actions for the management committee and, while anyone could read in the free library, only subscribers could borrow two books and one periodical. At first, subscriptions rates were 7/6 a quarter. This was later changed to £1 per annum, paid quarterly in advance. This was a considerable amount; 7/6 per quarter meant that the annual fee was £1.10. This was equivalent to about £650.00 or about $1,182.00AUD today, while the reduced subscription fee of £1 a year was the equivalent to £450.00 or about $818.00AUD today. Membership of the athenaeum would have been the reserve of the town's notable citizens. The vale of the catalogue lies not only in its historical connect with the establishment of the Athenaeum and the current museum, but also in its record of the names and positions of all members of the institution's committees of management from 1875-1876. This is a unique object that contains important records for a notable country town. Large brown leather bound book made in 1875 for the Beechworth library and museum by William Detmond.

Ilvaite has acquired its name from Ilva (Latin for Elba) Island, Greece, where Ilvaite is most commonly found. The geological setting in which Ilvaite occurs is through contact with magnetite, zinc and copper ore deposits, along with contact metamorphic deposits and zeolite zones. llvaite crystallizes in the form of black prismatic crystals and columns . This specimen was retrieved from Broken hill, known as the world's richest and largest zinc-lead ore deposit. Because of Ilvaite's often unaesthetic crystal formations compared to other minerals, Ilvaite is uncommon in most rock collections, particularly specimens that are not well formed, such as this one. Ilvaite is also a member of the Sorosilicate subclass of the silicate minerals, which have an unusual basic unit of Si2O7, making Ilvaite a unique mineral. Given that Ilvaite is not commonly found in Australia, it marks a unique contribution to an Australian collection of minerals. 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 hand-sized ferrous iron analogue mineral with of black with shades of beige Ilvaite is a brittle, opaque rock formation that has acquired its name from Ilva (Latin for Elba) Island, Greece, where Ilvaite is most commonly found.

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 found in Cape Patterson, Vic. Cape Paterson is a cape and seaside village located near the town of Wonthaggi, 132 kilometres southeast of Melbourne, in the Bass Coast Shire of Gippsland, Victoria, Australia. These dark, fossiliferous Mudstones were deposited in slow-moving water associated with sedimentary basins & continental shelves. They are rich in carbon which makes them almost black. This is typical of an anoxic, reducing environment such as deep water or stagnant conditions where carbon-rich material would remain unoxidised during subsequent deposition & diagenesis. it has an imprint of a leaf in the rock itself, displaying the fossil of the plant. This specimen is unique due to the leaf impression within the stone itself. Imprint fossils are formed from an organism moving in some way, leaving behind a trace or track. These tracks are preserved when the clay/silt dries slowly and is covered by other sediment. Plants can also leave imprint fossils when they are covered by sediment. The leaf tissue degrades, leaving an imprint of where the leaf once was.
