South Australia’s major source of feldspar for many years was a pegmatite body within Adelaidean Burra Group sediments 2 km east of Gumeracha in the Mount Lofty Ranges. Approximately 56 000 t of mixed quartz–feldspar rock known as ‘chinastone’ were mined betweenFeldspar - Wikipedia,Feldspars (KAlSi3O8 – NaAlSi3O8 – CaAl2Si2O8) are a group of rock-forming tectosilicate minerals that make up about 41% of the Earth's continental crust by weight. Feldspars crystallize from magma as both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known as anorthosite. Feldspars are also found in many types of sedimentary rocks. Feldspar minerals make up over 50% of Earth's crust.,6.35% of all Rare Earths deposits have Feldspar. 1.96% of all Feldspar deposits have Rare Earths. Gemstones: 26: 890: 2.92% of all Gemstones deposits have Feldspar. 1.82% of all Feldspar deposits have Gemstones.
