Geological specimen - Cerussite, Unknown c.1890s
... mining locality, mineral field and railway located on the western... mining locality, mineral field and railway located on the western ...Named in 1845 by Wilhelm Karl von Haidinger cerussite takes its name from the Latin cerussa, meaning 'white lead'. When viewed under certain lighting conditions cerussite gives of fire and rainbow-like colours (due to its high dispersion) and it is quite sought after by geological collectors for this very reason. Cerussite is usually found in the oxidised zone of lead ore deposits. It is a very common weathering product of galena and other lead ore minerals. It is a secondary mineral, meaning it forms as a result of the alteration of pre-existing minerals in the Earth’s crust. The presence of lead in cerussite makes it potentially toxic. Historically, it has been an important source of lead, which has numerous industrial applications, including in batteries, construction materials, and radiation shielding. Cerussite has a crystal structure that belongs to the orthorhombic crystal system. Its crystal structure is characterized by a three-dimensional arrangement of atoms in a repeating pattern. The crystal lattice of cerussite consists of interconnected lead (Pb) and carbonate (CO3) ions. This crystal structure is visible in the specimen. This specimen was found in Dundas (formerly Mount Dundas), a historical mining locality, mineral field and railway located on the western foothills of the West Coast Range in Western Tasmania. During the 1890s Dundas swelled in numbers however it is now lost in a temperate rainforest and its population is now 2. The present Dundas Extended mine, about 1.5 km east of Dundas is presently worked for specimen material.Faceted cerussite gems are considered rare and valuable, given the softness of the mineral. This item is not a faceted gem however its historical and scientific research potential give it significance; mined in an Australian township, this cerussite could shed light on the now lost history of Dundas and the mining that occurred there. Additionally, the uses of this mineral in historical industrial processes give it scientific significance. Such knowledge can add to understandings of the geographical and geological nature of Western Tasmania and allow for further study of Australian geological specimens.

Geological specimen - Chalcopyrite
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. 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.This hand sized solid mineral specimen has shades of brass-yellow with spots of iridescent green-black tarnish. 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 -

Geological specimen - Basalt (igneous-volcanic) containing Olivine, unknown
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.

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

Geological specimen - Smoky quartz crystals, unknown
Quartz is an extremely common mineral to find across the world. Quartz can have two forms; Microcrystalline quartz or Crystalline quartz. Microcrystalline quartz is a fine grain quartz where crystalline quartz is often a large crystal. This specimen is a crystalline quartz. Made of silicon oxide, this specimen is called smokey quartz crystals because of its brownish colour. However, the colour of quartz can vary. In addition, quartz are formed in deep-seated igneous rocks and crystallized through hot aqueous solutions. This type of crystal can be found all over Australia, including Beechworth in Victoria. Other places quartz can be found is the Ashburton River area in Western Australia, Marlborough in Queensland, the Lune River area in Tasmania and Kingsgate in New South Wales. This specimen is significant because it is common to find this kind of mineral. While the location of where this specimen was originally from is unknown, it highlights the many places in Australia where quartz is found. It demonstrates that quartz makes up a large portion of Australia's geology. In addition, quartz itself can vary in its colour and shape. This specimen represents one of these variations. That being smoky quartz crystals. 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.

Geological specimen - Dolomite
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.

Geological specimen - Malachite in Conglomerate, Unknown
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. 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. Although there is no indication available of the locality from which the specimen was sourced, it is likely that the specimen was collected either in South Australia in the vicinity of the Burra Burra mines or in Victoria as part of programs of geological surveying undertaken in the Nineteenth and Twentieth centuries. 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.

Agate occurs when amygdales (gas pockets) form in the upper levels of basaltic lava flows. If these pockets or bubbles are iniltrated by water bearing silica in solution, the fluid dries and hardens in layers, forming round or egg shaped nodules or geodes within the rocky matrix. Agate is formed of a silica mineral chalcedony similar to quartz. Although relatively common and semi-precious, agate has been prized since at least 1450 BC - an intricately carved agate seal was found in the 2015 excavation of a grave belonging to a Mycenaeum priest or warrior near Pylos in Greece. Agate is also used in jewellery and other decorative or ritual purposes due to its often striking appearance. Quartz is found all over Australia, including Beechworth in Victoria.

Geological specimen - Sphalerite, Unknown
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.

Geological specimen - Bituminous Coal, Unknown
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.

Geological specimen - Malachite, Unknown
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.

Geological specimen - Thunderegg agates, Unknown
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. 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.Two small solid specimens with pale, sandy-coloured exteriors and fractured internal patterns. burke museum, beechworth, geological, geological specimen, thundereggs, thundereggs agate, agate, rhyolite, rhyolite lava, volcanic ash, chalcedony, cryptocrystalline -

Geological specimen - Olivine Crystals, Unknown
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.

Geological specimen - Native (metallic) copper, Unknown
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.

Geological specimen - Malachite, Unknown
This specimen is a copper-carbonate malachite mineral. It is often found as crystalline aggregates or crusts, which have a banded agate-like appearance while also commonly found as botryoidal clusters of radiating crystals. Malachite is often bright green in colour, with dark green and blackish blooms or stripes/bands throughout the mineral. This particular specimen was recovered from the Burra Burra Copper Mine located Burra, South Australia. By the 1860's, South Australia was known as the "Copper Kingdom" due to its large amount of copper mines and huge success in the copper mining industry. Burra Burra was no exception to this phenomena, as this mining company was greatly famous and successful, being nicknamed the "Monster Mine". It was first established in 1848 and was the largest metal mine in Australia up until 1860. This specimen is significant as it highlights the historic use and value of malachite and the rarity of the mineral. Malachite is a rare gemstone which has been used in various ways historically. It has been cut and sculpted into beads for jewellery use as its rich colour and distinct yet unique patterns have made it a well sought after gemstone. Its' continued use over time only heightens the value and significance of this mineral.A hand-sized solid copper-carbonate hydroxide mineral specimen in shades of blue, green and copper tones throughout.MALACHITE / (Copper carbonite) / Locality: Burra, South Aust. | Malachite / Burra Burra / South Australia / (good specimen) / needs a wash / BBburke museum, burke museum collection, beechworth museum, beechworth, geological specimen, geological, mineral, mineraology, copper carbonate, malachite, burra burra mine, copper mining -
