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. 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 smaller than hand sized rock specimen which is dark grey in colour with small holes and white deposits across its surface.Geological survey / [illegible] /burke museum, beechworth, geological specimen, geology, basalt, basalt specemin, indigo shire, talbot, cainozoic, igneous rock

Dendrites are deposits of black minerals, typically manganese oxides that precipitated from water seeping through fractures in fine-grain rocks like a sandstone or limestone. Dendrites are much less regular than plant fossils and lacks vein structures. The manganese cryztallizes through the process called 'supercooling'. Some samples of dendrites occur in volcanic rocks in the Lilydale district, east of Melbourne. Sandstones are made of tiny sand grains that may have been deposited in the sea and later formed together. Most sandstones are made of quartz which are chemically-resistant minerals. This particular specimen was donated by Alfred Selwyn in 1868 as part of the Geological Survey of Victoria. It is connected to the original 1875 catalogue on Geological Specimen with number 189 'Quartz Crystals_Quartz Crystals (two are polished)'Dendrites on sandstones This specimen is an important contribution to the geological history of Victoria, as well as its links to the 1868 Geological Survey of Victoria. This specimen is part of larger collection of significant geological specimens in the Burke Museum that was collected from around the world between 1868-1880. A large percentage of these specimens were collection as part of the Geological Survey of Victoria 1852-1974. The Geological Survey of Victoria was an organisation founded in response to the Victorian gold rush to explore the geological and mineral resources and to record a detailed map of the state. It was headed by British geologist, Alfred Richard Cecil Selwyn (1824-1902), who was responsible for issuing over 60 geological maps during his 17 years as director. These maps were all hand-drawn and coloured and became the benchmark for accuracy for geological mapping. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.

Kaolin is also known as china clay. This specimen came from Dunolly, Victoria and was donated to the Museum in 1868 as part of the Geological Survey of Victoria. This survey helped map and study the geology of Victoria. In Victoria, Kaolin is particularly used as a filler and coating material in paper manufacture. It can also be used in paints, ceramics, rubbers and plastics. There are many kaolin deposits in Victoria but many of these have been mined out and there is not much Kaolin left. Rocks that have a high amount of Kaolinite and it can be formed through the decomposition of other materials. There are two types of Kaolin; hard and soft kaolin. Soft kaolin's are coarse but have a soapy texture. It can also break easily. The hard kaolins have an earthly texture and are finer grained. This means that they are harder to break, unlike the soft kaolin. Hard kaolin's are formed by flocculation in salt water, a process that in basic terms, bonds particles together. Kaolin is a common material in Victoria and that is why it is significant. While this specimen was mined in Dunolly, Victoria Kaolin can also be found Pittong, Pakenham, Bulla, Hallam and Ballarat as well as many other places throughout Victoria. This specimen represents the presence of Kaolin deposits in this region of Australia. It is also significant because Kaolin has many uses and is largely beneficial to many manufacturing processes in 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.

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.

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. These specimens originated in North Queensland, which contains noted agate-fossicking regions such as in the area surrounding Forsayth. They were collected in approximately 1852 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 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.

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.

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 discovery of gold in Victoria, for instance, had a significant influence on the development of the area now known as 'the goldfields', including Beechworth; the city of Melbourne and Victoria as a whole. Dolomite and limestone are mined at several locations in Victoria, including sites in the North-East of the state in Bindi and Limestone Creek. There are notable dolomite deposits in most Australian states. The dolomitised form of the mineral tends to come from older limestone deposits, formed during the palaeozoic era in marine settings, so this specimen may have come from a deposit located along a coastline in Victoria or another state. The specimen is significant as an example of surveying activity undertaken to assess and direct the development of the mineral resource industries in Victoria and Australia, as well as the movement to expand human knowledge of earth sciences such as mineralogy and geology in the nineteenth century.

This specimen was recovered from the Nigretta Falls (previously named the Upper Wannon Falls), Victoria. The falls are fed by the Wannon River that has its head waters in the Grampians mountains. Approx. 10km upstream of the Wannon Falls, Nigretta is a multi-channel segmented cascade of smaller drops and bounces guided by patterns of joints in a much older (Devonian) rhyolitic volcanic rock. Both the Wannon and Nigretta Falls are iconic landscape features, entrenched in the history and identity of the region. These falls are particularly rare as they are the product of volcanic activity, which is unique in the context of the Volcanic Plain of Victoria. Waterfalls of this capacity are generally associated with the Uplands areas of Victoria, rather than the edges of the Volcanic Plain.

This specimen is 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. 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 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.
