Summary:

The whole-rock and isotope geochemistry of the evaporites are used as an important criteria to distinguish ancient marine types from non-marine types. The studied gypsum and anhydrite samples from different lithofacies display enrichment in LREE (LaN/LuN, 4.243-0.964) and differences in Ce/Ce* anomaly (1.283-0.859), Ni, Cu, Co, Fe and Mg contents implying continental input. The Sr contents of the samples are from 806 to 6464 ppm in gypsum, 1023-1197 ppm in anhydrite and 631-15150 ppm in claystone-mudstone-limestone suggesting importance of marine-derived Sr, but particularly high Sr contents are related to epigenetic celestite formation. Mineralogic, petrographic and geochemical evidences indicate Ca-sulphate precipitation in a shallow marine environment.
