This work presents original data on the contents and distribution of major and rare earth elements in the waters from 26 mud volcanoes within the Kerch–Taman region. In terms of the chemical composition, the studied mud volcanic waters are the Na–Cl and Na–HCO3–Cl types. However, the Cl/Br, Na/Cl, and Y/ Ho ratios indicate three main genetic groups of volcanoes. It was found that the contents of the rare earth elements in the aqueous phase of mud volcanoes are low (fractions of μg/L) and are dis
