title: Sr Isotope Composition of Mud Volcanic Waters in the Kerch–Taman Province
abstract: Waters at seventeen mud volcanoes of the Kerch–Taman province in the Northwestern Cis-Caucasus region have been analyzed for Sr isotope composition. The 87Sr/86Sr ratios vary from 0.70734 to 0.71076 and show positive correlation with δ18О, 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.
