The sulphur and oxygen isotopic composition of anhydrite from the Upper Pechora Basin (Russia): new data in the context of the evolution of the sulphur isotopic record of Permian evaporites
This study describes a new determination of the S and O isotope composition of Lower Permian (Kungurian) anhydrites from the Upper Pechora Basin, Cis-Ural region, Russia. delta S-34 values in sulphate facies vary from +13.7 to +15.1%(0); and delta O-18 values range from +9.3 to +10.4%(0). The values...
