Lithogeochemistry of Kungurian evaporates western side of Yuryuzan'-Sylva depression (Permian Country)

Abstract

New geochemical data on carbonate and sulphate evaporates of Kungurian stage of the Permian system showed a complicated element distribution which is defined both sedimentary features and its further evolution. The main geochemical specialization of trace elements is determined not so much by sea water chemistry as presence of the terrigenous materials from the Urals femic rocks destruction. Epigenic transformation of evaporites leads to element losing and formation of new minerals (pyrite, celestite, barite, fluorite, powellite, vanadinite, iron and manganese hydroxides).
