title: Mud Volcanic Fluids of the Kerch–Taman Region: Geochemical Reconstructions and Regional Trends. Communication 1: Geochemical Features and Genesis of Mud-Volcanic Waters
abstract: The chemical and isotopic characteristics (δ18O and δ2H) 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°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).
