granites are generally associated with generation of S-type suites of granites in thick arc and back-arc fold belts where subducted sedimentary and felsic rock is melted. Distribution Examples of greisen are: Tin and tungsten deposits of Cornwall Ardlethan, New South Wales, Australia (tin-antimony greisen) Timbarra gold mine, New South Wales, Australia (gold greisen deposit) Anchor Mine, Lottah, Tasmania, Australia (tin copper topaz greisen) Pitinga topaz granite, Brazil (tin, topaz, beryl) Lost River, Alaska, USA (tin greisen) Sisson Brook, Burnt Hill and other deposits, New Brunswick, Canada (tin-tungsten-molybdenum greisen) Erzgebirge, Czech Republic (tin greisen) Panasqueira Mine, Portugal Tin and Tungsten deposit The Tin Range Tungsten-Tin deposit, Stewart Island/Rakiura, New Zealand See also ; specifically for S-type and I-type distinction References Evans, A.M., 1993.
