title: δ11B in Mud Volcanic Waters of the Kerch–Taman Mud-Volcanic Area (Crimea–Caucasus Region): Genesis and Formation Conditions of the Boron Mineralization
abstract: The isotopic-geochemical characteristics of boron in waters of 21 mud volcanoes in the Kerch–Taman area have been determined. Boron concentration varies from 14 to 550 mg/L, and δ11B values range from +8.3 to +54.7‰ (+21‰ on average). Low δ11B values (~+14‰) were also obtained in two freshwater samples collected from aquifers of Neogene–Quaternary sediments. These data reflect the high heterogeneity of boron isotopic characteristics in waters of various genesis, which are discharged on the Earth
