Sartorite is a lead arsenic sulfide with the chemical formula PbAs2S4 and as type locality the Lengenbach Quarry in Legenbach, Binnental, Valais, Switzerland.[2][3] Historically, sartorite has been thought isomorphic to chalcostibite, emplectite, and zinckenite, but was definitively distinguished from the others in 1939.[4]
The mineral is named after its discoverer, Sartorius von Walterhausen (1809-1876).[5]
The mineral is predominantly found in hydrothermal deposits in dolomite. Sometimes the mineral is containing traces of thallium and has been reported from:[2]
