The isotopic-geochemical characteristics of boron in the waters of 21 mud volcanoes of the Kerch-Taman region have been determined. Boron concentration varies from 14 to 550 mg/L, and δB values range from +8.3 to +54.7‰ (+21‰ on average). Low δB 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 and discharged on the Earth&amp;
