New data on the material composition of mud volcano products on Kerch Peninsula

Resumo

The results of recent studies of the isotope and chemical composition of the waters and breccias that erupted from mud volcanoes of Kerch Peninsula are presented. It was found that the waters of the volcanoes considered were characterized by low salinity, a chloride–hydrocarbonate–sodium composition, and an increased ¹⁸O content. The breccias were enriched in organic matter and some microelements (Li, Se, Hg, etc.). As for petrogenic elements, depletion of Ca in the breccias is noted.
