| Реферат: | eng: Waters at seventeen mud volcanoes of the Kerch-Taman province in the Northwestern Cis-Caucasus region have been analyzed for Sr isotope composition. The Sr-87/Sr-86 ratios vary from 0.70734 to 0.71076 and show positive correlation with delta O-18, as well as with fluid generation temperatures estimated using the Mg-Li geothermometer. The results revealed that the mud volcano system of the province was separated from the fluid systems of deeper Mesozoic sedimentary strata that fill the West Kuban Basin. The mud volcano water budget includes a major contribution from dehydration waters that release during illitisation of smectite, which occurs within the Maykop Shale sedimentary sequence. At the same time, Sr-87/Sr-86 ratios reflect lithological and geochemical heterogeneity of shallow sedimentary strata of the West Kuban Basin.
