Feldspar, derived from the German word feldspat, is a group of minerals which is the most common mineral group found on Earth, making up more than half of the planet's crust. The major rock-forming minerals in the Feldspar group include albite, anorthite, orthoclase and microcline. (Mindat, Feldspar Group). Orthoclase is part of the Feldspar Group subgroup, Alkaline Feldspar, which are known to be poor in calcium, and mostly rich in potassium. It is further also considered to be a K Feldspar, a subgroup of Alkaline Feldspar that are Potassium-dominant with variable crystal symmetry and Al-Si ordering state. Orthoclase are most commonly Colorless to white, Greenish white, Grayish yellow, or Pale pink and transparent to translucent with slightly pearly cleavage. The mineral rates at a 6 on the Mohs Hardness Scale. (cannot be scratched with a knife, but scratches glass with difficulty). The stronger green colour of this particular specimen is distinctive to the Broken Hill region (where it was found), and due to a small amount of lead. (BB) Its qualities find it misidentified at times as as microcline variety amazonite. Broken Hill is one of the world’s richest lead-zinc-silver deposits. The huge, 300-million-tonne orebody was discovered in 1883 and the superb mineral specimens attract collectors from around the world. (Australian Museum, Minerals from Australia: Australian mining regions)While feldspar is not by any means rare, this particular specimen has qualities distinctive to the Broken Hill mining district, with these properties leading at times to the mineral's misidentification. This creates potential for further study and identification of these mineral deposits through methods such as microscopic twinning, or using the position of certain d values in XRD patterns to calculate the degree of disorder of a K-feldspar, as discussed on the Mindat website (Mindat.com, Orthoclase:About Orthoclase). 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 solid small aluminosilicate mineral composition which is primarily pale green and blue-grey in colour with traces of beige and white throughout. Note: green plumbian orthoclase (aka green feldspar) is an indicator mineral for the Broken Hill style lead-zinc deposits.N/Abroken hill mine, geological specimen, minerology

John Perry Collection. Laminated copy of worksheet identifying inundated artifacts at Lake Eppalock when at 10% capacity. The dam was built by the State Rivers and Water Supply Commission of Victoria. The dam wall height is 45 metres (148 ft) and the main embankment is 1,041 metres (3,415 ft) long. At 100% capacity the dam wall was designed to hold back 304,651 megalitres (6.7014×1010 imp gal; 8.0480×1010 US gal) of water. The surface area of Lake Eppalock is 3,011 hectares (7,440 acres) and the catchment area is 2,124 square kilometres (820 sq mi). The controlled spillway is capable of discharging 8,040 cubic metres per second (284,000 cu ft/s). Lake Eppalock supplies both stock and domestic water to the Campaspe irrigation district. It also serves as a water supply to Bendigo and Heathcote and, in more recent times, Ballarat. The lake is a major attraction for those engaging in watersports, with a number of tourist parks and accommodation facilities available. Permissible activities on the lake include high-speed boating, water skiing, sailing, canoeing, fishing and swimming. The lake's water levels were low for approximately eight years between 2002 and 2010 during a prolonged drought, which restricted the amount of recreational activity until rainfall in the latter half of 2010 returned the lake to 100 percent capacity. Built between 1961 and 1964, Lake Eppalock remains the only water storage on the Campaspe River system.map, artifacts, eppalock, reservoir
