摘要	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 of delta S-34 and delta O-18 of anhydrite from halite facies varies from +12.6 to +15.0%(0). and +7.5 to +10.9%(0). respectively. The quantitative ratio of pyrite content from the water-insoluble residue (silty-sand fraction) is characterized by extremely low (<<1 %) to high (4-5%) steep gradation values. The increased presence of pyrite indicates the influence of bacterial sulphate reduction. The sulphate reduction process was more intense, especially when evaporites were formed in mud. The narrow fluctuation range of sulphur and oxygen isotopes values of the measured anhydrite indicates low levels of fractionation. It was established that during the Permian, evolutionary changes in the content of sulphate ions in sea water correlate with the sulphur isotopic composition of marine evaporites.
