Geochemistry of Rare Earth Elements in Volchansky CO 2 -Rich Mineral Water and Mineral Precipitations (Sakhalin Island, Far East of Russia)
Abstract Distribution and abundance of rare earth elements in Volchansky Spa of CO 2 -rich mineral waters and REE fractionation during the formation of Fe 2 O 3 precipitates on the Sakhalin Island (the Far East of Russia) were studied. The main common features of waters are Na-Cl-HCO 3 hydrochemical...
