Malachite is typically found as crystalline aggregates or crusts, often banded in appearance, like agates. It is also often found as botryoidal clusters of radiating crystals, and as mammillary aggregates as well. Single crystals and clusters of distinguishable crystals are uncommon, but when found they are typically acicular to prismatic. It is also frequently found as a pseudomorph after Azurite crystals, which are generally more tabular in shape. This particular specimen was recovered from the Burra Burra Copper Mine in Burra, South Australia. Otherwise known as the 'Monster Mine', the Burra Burra Copper Mine was first established in 1848 upon the discovery of copper deposits in 1845. Within a few short years, people from around the world migrated to Burra to lay their claim in the copper economy. By April 1848 the mine was employing over 567 people and supporting a population of 1,500 in the local township. Up until 1860, the mine was the largest metals mine in Australia, producing approximately 50,000 tonnes of copper between 1845 to its closure in 1877. The Burra Burra Mine was also famous for a number of other specimens, including; crystalline azurite, cuprite, and botryoidal and malachite. Malachite is considered a rare gemstone in that the original deposits for the stones have been depleted leaving behind very few sources. In addition, the use of Malachite as gemstones and sculptural materials remains just as popular today as they were throughout history. It is quite common to cut the stone into beads for jewellery. The fact that Malachite has such a rich colour and one that does not fade with time or when exposed to light makes it particularly rare. 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.

Malachite is a green copper carbonate hydroxide mineral and was one of the first ores used to make copper metal. Malachite has been utilised as a gemstone and sculptural material in the past as its distinctive green color does not fade when exposed to light or after long periods of time. Malachite is formed at shallow depths in the ground, in the oxidizing zone above copper deposits. The material has also been used as a pigment for painting throughout history.

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.

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.

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".

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

Gabo Island sits off the coast of East Gippsland in Victoria, with cliffs of granite in a relatively unique red/pink colour. Early attempts to build a lighthouse on the island were abandoned due to poor foundations, but when a ship ran aground on the nearby Tullaberga Island in 1853 and led to the death of 37 people, efforts were reignited. Construction of a new lighthouse was completed by 1858, using Gabo Island granite. The lighthouse is Australia's second tallest in Australia and continues to play an important role in guiding boats around the coast as they journey between Melbourne and Sydney. The distinct pink colour from the granite means the lighthouse continues to be a defining feature of the island. Gabo Island granite was also used to construct the Treasury Building at 117 Macquarie Street in Sydney, now the Intercontinental Hotel.Granite in the pink colour of this specimen is relatively rare. The connection to the lighthouse on Gabo Island also gives the specimen historic significance and social significance regarding the maritime history of Victoria.

Granite is formed by the slow crystallisation of magma below the earth's surface. It is typically composed of a mix of quartz, feldspar, and other minerals, though syenitic granite like this sample has a smaller amount of quartz than typical granite. This different mineral composition leads to the more distinct pink and red colouring.First sticker: [torn]logical survey / R........

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.

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

This specimen was recovered from Wonthaggi in Victoria. Coal is a sedimentary rock which is composed of peat after it has been exposed over millions of years. This is an example of Australian black coal which is used as either thermal or coking coal for electricity generation or manufacturing processes. It is predominantly composed of Carbon which is 'C' on the periodic table of elements. This early example of a coal sample, shows the important role that coal played/plays in Australia's energy generation and manufacturing processes.

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.

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 specimen is from Barefoot Hills, Victoria. Sandstones are economically important as major reservoirs for both petroleum and water, as building materials, and as valuable sources of metallic ores. Most significantly, they are the single most useful sedimentary rock type for deciphering Earth history.

Gold usually is found as a native metal, but it also forms minerals with tellurium, sulphur, or selenium. The gold-bearing minerals that contain tellurium are called tellurides. Kalgoorlie, Western Australia contains greater than 1500 tonnes of gold.Seventy to seventy-five percent of the deposit occurs as native gold, but a further twenty percent appears as tellurides. What remains is in the form of 'invisible' gold. Extracting gold from telluride minerals, such as calaverite, which contains around forty-two percent gold, has produced approximately three hundred tonnes of gold. Prior to 1896, rocks containing tellurides were not recognised as rich gold ores, and were discarded.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 recovered from Moonambel, Donkey Hill, Victoria. Established in the early 1860's, Moonambel is a small town in the Pyrenees region of the Australian state of Victoria. In the 1850s the location of Moonambel was part of the ‘Mountain Creek’ pastoral run, but in 1860 reports began to appear of a gold-rush at McKinnon’s ‘Mountain Creek’ station. By 1861, a township had developed on the diggings site, and on 21 October 1861 the “municipal district of Moonambel, on Mountain Creek” was proclaimed. The name 'Moonambel' is believed to be an aboriginal word meaning 'hollow in the hills'. Slate is a stone with a fine grain that is noted for its persistent strength and ability to naturally split into slabs. It forms under low temperatures and is most often created from clay. Pyrite is a crystallising compound that occurs naturally in grey and blue-black slate that is colloquially referred to as slate-rust as it resembles regular rust.

This specimen was recovered from Adelong, NSW. The initial discovery of gold at Adelong by a Mr Williams took place in 1857. Much of the area is underlain by granitic rocks, while at Adelong itself a prominent norite intrusive body occurs. To the west of Adelong is a belt of intermediate to mafic igneous rocks and sediments which extends from Batlow in the south to at least as far north as the Snowy Mountains Highway. Around 26 tonnes of gold was found at the Adelong goldfield from its discovery in the 1850s until the last miners left in the 1940s. Pyrite has the formula of FeS2 and forms as an isometric (cube) form. It is a common occurring material and is often mistaken for gold, now colloquially known as ‘fool’s gold’. Pyrite that has strongly crystallised is considered stable, but the mineral has the potential to oxidise and decay.

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. 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.An angular, solid hand-sized piece of grey volcanic Basalt with green/brown Olivine phenocrysts along one flat edge.Olivine in basalt / - label is probably / correct. / C.

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.

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’.

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 a native copper specimen that is metallic. Copper is typically found in the earth's crust and is often found alongside other metals such as gold, zinc, lead and silver which all belong to the same group which is the Copper/Gold group. Copper is most commonly formed from large masses of molten lava rock which has solidified in the earth's crust and over time though different sizes and speeds of crystal growth has turned into large amounts of copper, stored in porphyry copper deposits. Copper has a distinctive colour, yet can sometime appear blue and greenish which is often caused by oxidisation or a mixture of copper and other metals. This specific specimen was recovered from Moonta, South Australia. The Moonta Mining Company was established in 1861, after a Shepard in the area noticed traces of copper. This lead to a rush in the copper mining industry which was relatively young in Australia at the time, making Moonta Mining Company one of the richest in Australia. By the 1860's, South Australia had been nicknamed the "Copper Kingdom" due to its vast amount of Large copper mines and resources. As of 2016, Australia was the second largest producer of Copper internationally, following behind Chile in first place. This copper specimen is significant historically and scientifically as it is such an important metal commonly used throughout the world in various ways. Copper is an invaluable recourse used in daily life, used in most electrical appliances as it is a great conductor of heat and electricity, as well as being soft and malleable, making it easy to bend and mould into delicate sheets and wires. Copper does not corrode and is therefore used in the production of water pipes among countless other significant necessities that are often overlooked in our society. Historically, Copper holds great significance as it was the first metal used by humans. It was discovered roughly 9000 years ago and was utilised by the Neolithic Man who learnt that heating the metal made it more malleable, thus tools and utensils were made which were far superior to the previous stone tools used by humans. This history and its connection to the current and ongoing relationship between humans and copper must be preserved and highlighted as it is integral to the history of all humankind.

Galena Chalcopyrite is the earth's primary ore of lead and is mined from a large number of deposits in many countries. It is also an important source of silver. Galena Chalcopyrite is one of the most abundant and widely distributed sulfide minerals across the world. The mineral is found in igneous and metamorphic rocks in medium- to low-temperature hydrothermal veins. This specific specimen was recovered from the mines in Broken Hill, New South Wales. The mines in Broken Hill were first established after Charles Rasp discovered a large amount of silver-lead-zinc ore-body in the area in 1883. BHP (Broken Hill Proprietary) mining company was then established in 1885 and quickly became the lead in Australia's mining industry after they began excavating and exporting the country's largest amount of lead, silver, and zinc. This feat generated over $100 billion in wealth for the company.Galena Chalcopyrite is signifiant as it represents the catalyst for the rise of Australia's most influential mining companies - BHP. The mineral was one of the first to be mined in the country and after being made into lead, was used for a variety of things such as paint, batteries, ammunition, and plumbing materials before it was known to be harmful to humans. 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.

Feldspathic arenites are sandstones that contain less than 90% quartz, and more feldspar than unstable lithic fragments, and minor accessory minerals.Feldspathic sandstones are commonly immature or sub-mature.These sandstones occur in association with cratonic or stable shelf settings. Feldspathic sandstones are derived from granitic-type, primary crystalline, rocks. If the sandstone is dominantly plagioclase, then it is igneous in origin Sandstone features prominently in public buildings throughout Victoria. Most of the sandstone used as dimension stone in the State came from three sources: the Heatherlie quarry in the Grampians (Silurian), the Bacchus Marsh area (Permian), and the Barrabool Hills near Geelong (Cretaceous).Sandstone features prominently in public buildings throughout Victoria, making this specimen special as it shows the materials used by Victorian building companies. Sandstone can also be crushed, crushed stone is used in the construction of roadways and road structures such as bridges, and in buildings, both commercial and residential. 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 feldspar-rich sandstone, a sandstone intermediate in composition between an arkosic sandstone and a quartz sandstone, containing 10% to 25% feldspar and less than 20% matrix material of clay, sericite, and chlorite. Feldspathic arenite containing less than 90 percent of the composition of quartz. Feldspar is the main composition. Feldspathic arenite may contain fragments of unstable rock, and a little amount of other minerals such as mica and heavy minerals. Some feldspathic arenite have pink or red color because of the presence of potassium feldspar or iron oxide. There are also colored light gray to white. These sandstones are usually medium to coarse grained and can contain a high percentage of granules with angular until subangular roundness. The content of the matrix can appear as the rest up to more than 15 percent, and sorting of grains can present as moderate to poorly sorted. Feldspathic sandstones are generally immature in textural maturity. Feldspathic arenite can not be judged from the structure of the sediment. Bedding can emerge from the laminate parallel to the crossbed. Fossils may appear in the layer deposited on the sea. Feldspathic arenites usually appear on the craton or the continental shelf, which can be associated with conglomerate, quartz lithic arenite, carbonate rock, or evaporites. This sandstone may also appear on the succession of sedimentary basins deposited on an unstable or deep sea, and moving arc setting. According to Pettijohn (1963) Arkose make up about 15 percent of all sandstones. Some Arkose formed in situ when the granite and related rocks disintegrate and generate granular sediments. Most of the material feldspathic sandstones derived from primary crystalline granitic rocks, such as granite or metasomatic rocks containing abundant potassium feldspar. Mineral contained in sandstones is mostly a form of plagioclase feldspar derived from quartz diorite or volcanic rock. Feldspar contained on this sandstone comes from arid to cool climates when the chemical weathering process is reduced.sandstone, natural stone, feldspathic sandstone, burke museum, geology, geological, geological specimen

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.

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

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 specimen originated from Mount Lyell on the west coast of Tasmania, where a large group of open cut and underground copper-silver-gold mines began operating in 1883. Between 1893-1994, the Mt Lyell Mining and Railway Company were responsible for operations. The Mt Lyell copper-gold mines produce some excellent crystallised specimens of chalcopyrite and other minerals. The deposits are generally considered to be of Cambrian volcanic origin, but there are indications of Devonian granitic influence on the ores, plus local remobilisation during Devonian deformation. Over 120 million tonnes of ore was produced from several workings, including the main Prince Lyell mine and the North Lyell mine, which was also of great importance. The Mount Lyell mines have a long history of human and environmental disasters, including the 1912 North Lyell fire that killed 42 miners, and two separate incidents in 2013 in which three people lost their lives. The environmental impacts from this complex of mines are extensive, with waste tailings and heavy metal contamination flowing directly into the King and Queen River catchments. In 1954, the eminent Australian historian, Geoffrey Blainey, published 'The Peaks of Lyell' which delves into the history of the 1912 North Mount Lyell Disaster.Chalcopyrite does not contain the most copper in its structure relative to other minerals, but it is the most important copper ore since it can be found in many localities and occurs in a variety of ore types. The brassy-yellow colours in Chalcopyrite mean it is often confused with pyrites and gold, leading to use of the term, "fool's gold." Chalcopyrite has been the primary ore of copper since smelting began five thousand years ago. 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.

Chalcopyrite is a copper iron sulphide mineral and a major ore of copper common in sulphide veins and disseminated in igneous rocks. Chalcopyrite has a hardness of 3.5-4 on the Mohs Scale. It is a member of the tetragonal crystal system and has metallic lustre and opaque transparency.burke museum, beechworth, indigo shire, beechworth museum, geology, geological specimen, chalcopyrite, copper pyrites, copper mining, tasmanian geology, mount lyell, mount lyell mines, fools gold, mohs scale, crystals, minerals, historical geological collection, victorian geological survey, a.r.c selwyn, gold rush, van diemans land
