Characteristic of rare-earth element distributions in mud volcanic waters

Abstract

The original results on the distribution of rare-earth elements in the waters of mud volcanoes in Sakhalin Island, Taman Peninsula and Azerbaijan are presented. It has been shown that mud volcanic waters with total content of rare-earth elements less than 0.5 mcg/l are enriched with heavy lanthanides and characterized by a deficiency for Cerium. The Yuzhno-Sakhalinsk mud volcano demonstrates higher rare-earth element content in active griffons according to our study.
