Реферат: | eng: The chemical and isotopic characteristics (delta O-18 and delta H-2) of water from 42 mud volcanoes of the Kerch-Taman region (Crimean-Caucasus district) were analyzed. The formation temperatures of mud volcanic waters were estimated using the Mg-Li hydrochemical geothermometer (t(Mg-Li) = 40-134 degrees C). It was revealed that dehydration waters released during the smectite-to-illite transformation play significant role in the total fluid balance of the mud volcanic systems (up to 80% of the total fluid volume). These waters are characterized by low Cl ion contents, delta O-18 from +13 to +17 parts per thousand, and delta H-2 from -25 to -20 parts per thousand relative to VPDB, and high concentrations of HCO3-, B, Li, Ba and other trace elements. Correlations between the concentration of HCO3, B, delta O-18, and t(Mg-Li) values were revealed.
