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

This mineral is commonly found in caves. The term 'Dogtooth Spar' refers to the crystal-like structure within the mineral which is grown in calcite-rich water, thus forming calcite crystals. The environments necessary for these crystals to form is commonly within the water within caves, which are consistently supplied with calcium over a long period of time. It is also known as a scalenohedral crystal.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 mineral calcite, with a grey base and white crystal structures emerging upwards from the base.dogtooth spar, scalenohedral crystal

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.
