Galena occurs in a range of deposit contexts, often in metalliferous veins, such as Broken Hill, Australia; Coeur d’Alene, Idaho, United States.; Clausthal Zellerfeld, Germany; and Cornwall, England. Large deposits also replace limestone, dolomite, or occasionally organic matter, or have a contact-metamorphic origin. Galena is additionally found in cavities, brecciated (fractured) zones in limestone and chert, and in coal beds. This specimen was recovered from Broken Hill NSW and is 60% lead with 8-12 oz/silver to the ton.Galena or 'lead glance' is a grey lead sulfide and the chief ore mineral of lead. It forms isometric crystals in which the ionic lattice is similar to sodium chloride. Galena is brittle and easily weathers to secondary lead minerals, with the upper part of mineral deposits often containing cerussite, anglesite, and pyromorphite. It usually contains silver, which is mined along with its lead content. Other commercially important minerals that form in close association with galena are antimony, copper, and zinc. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. 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 small-sized solid specimen containing one mineral with a sparkly silver metallic lustre exterior and pastel-grey interior.geological specimen, geology, geology collection, burke museum, beechworth, galena, lead sulphide, alfred selwyn, broken hill

This specimen is from Broken Hill, NSW. Galena is a natural mineral form of lead sulphide and is often found associated with sphalerite, calcite, and fluorite. Galena is an important lead ore mineral, and, in some regions, it is also an important mineral associated with silver ore. Sphalerite is a sulphide mineral that is the main ore of zinc. Rhodonite is an uncommon mineral once used as an ore of manganese in India, however today the scarcity and fragility of the crystals mean it is primarily used as lapidary materials or mineral specimens. In 1883, Charles Rasp who was a boundary rider at the time, discovered what he thought were deposits of tin but were in fact samples of silver and lead. He and six others went on to set up the first mining company in Broken Hill (BHP). The ore body became the largest and richest of its kind in the world mining ore worth more than 42,000 pounds in its first year. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study. Galena contains lead and silver, Sphalerite contains zinc.

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

Majority of Galena in Australia is found in hydrothermal deposits emplaced around 1680 million years ago which have been heavily metamorphosed. Galena is the natural mineral form of lead sulfaide. It occurs generally as fine to large crystals due to syntectonic remobilization at low temperatures and moves to a suitable location. The colour is a shining lead and silvery gray with high specific gravity between 7.2 and 7.6 gms/cm3 and contains 86.6 lead sulfaide in its purest form. Its cyrstal system is cubic with perfect cleavages, and contract penetration and lamellar twinning. This particular specimen is from the Broken Hill mine, it is one of the largest lead mines located in Western New South Wales and still has ore reserves amounting to 20.9 million tonnes of ore grading of 7.4% lead, 9.4% zinc, and 61.5 million oz of Silver. Throughout its history, it has produced over 200 million tonnes of ore throughout its 127 years of mining history dating back to 1885. Galena mineral ore found in Australia is considered rare, as it is only currently found in the Broken Hill Mine of Western New South Wales. It represents heritage value through the systematic collecting of the geological surveyers in Victoria and Australia during the early to late 19th Century. The fact that it is only found in one mining area of Australia, shows that this specimen is rare for examples of Australian Galena. This mineral specimen is one part to a larger collection, aquistion, and distribution of Garnet in Galena around Australia and parts of the world and donated to the Burke Museum between 1860-1880. While this specimen was not found by the Victorian Geological Survey, it shows the historical need for mapping geological areas around the Gold Rush region to further identify areas of precious metal and gem aquisition. Additionally, collecting these specimens was an important part of mapping the scientific make up of the earth's surface. Many were sent to institutions for further contribution to research and scientific knowledge of the specimens.

Garnet is a popular gemstone used in jewellery due to its hardness and durability. There are about 5 varieties of Garnet, which distinguish the colour of each stone. In Australia mostly Pyrope and Aimandine varieties are found; Pyrope, which is blood-red to black and Aimadine, which is brownish-red to black. Other varieties are rarely found in Australia. The garnets visible in this specimen are likely Pyrope. Galnea is the natural mineral form of lead sulphide and has had various uses throughout history; from makeup to car batteries. It was first mined in South Australia in 1841. Green feldspar is an amazonite mineral, a variety of the potassium feldspar called microcline. This particular mineral is considered uncommon. It has been used in jewellery throughout history. It is likely that this specimen was found in Broken Hill, NSW, presumed due to findings of specimens with similar combinations. Broken Hill is Australia’s longest-lived mining city. The city’s fortunes have come and gone against an extreme economic background of boom and bust which continues today.This geological specimen is a rarity, given that is formed of three distinct minerals and the richness of colour that remains visible in this item attests to the strength of each structure. As we cannot pinpoint exactly where this specimen was found further research can only strengthen what is known about mining within Australia. As such the item is significant due to its scientific rarity and its ability to represent three specimens in one.

Calcite is a common mineral and is found worldwide due to it being a primary component of many other rocks such as limestone and marble. It is a softer mineral that scratches easily and is often found colourless or with a cream/white shade but may show up in colours such as red, yellow, green, and violet. In sedimentary rocks calcite is often found in the form of invertebrate shells, making it an important biomineral. Calcite is used in many industries such as farming, building, and medicine. This particular specimen was found at Broken Hill mine in Broken Hill, New South Wales, Australia. Broken Hill mine is one of the largest mines working silver and lead in Australia and at its peak employed 6500 staff across 7.5km long of land. The site was founded in 1883 by Charles Rasp, where Rasp and 6 other men from various backgrounds came together to form the first BHP mine. It has become one of the most popular mining sites due to its abundance and longevity. The ore body was created 1685 million years ago due to volcanic activity causing heated seawater to flow up through the seafloor where it mixed with the cold water creating black sulphide precipitates. These then settled back onto the seafloor forming sediment layers rich in minerals. Over time the land eroded until it was discoverable by humans.Historically this specimen is significant due to the origin of its location. Broken Hill mine has a long history in both its location and its findings and has resulted in a variety of minerals being discovered at its site. It is beneficial in the understanding of the Australian landscape over millions of years. Due to its properties, calcite today is used in a multitude of different industries such as agriculture, construction, medicine, and farming.A small sized calcium, carbon and oxygen made mineral specimen in shades cream and greycalcite, mineral, limestone, marble, sedimentary, invertebrate shells, biomineral, farming, medicine, broken hill, broken hill mine, new south wales, charles rasp, syndicate of seven, volcanic activity, black sulphide precipitates, calcite crystals, beechworth museum, indigo shire, beechworth
