REE BEHAVIOR IN TIN-BEARING HYDROTHERMAL-MAGMATIC SYSTEMS (AN EXAMPLE OF DEPOSITS OF THE FAR EAST)

Abstract

REE behavior in hydrothermal-magmatic systems has been imperfectly understood, although these data could play a crucial role in understanding mineralizing processes. The study of the REE fractionation processes in hydrothermal media holds the great interest in the comprehension of a fluid evolution during the mineral formation and could give important information to reveal fluid sources and its physicochemical parameters. The research of factors controlling REE distribution in the fluid/mineral system is one of the prime problems in estimating the media parameters. An investigation of REE in minerals of tin-bearing hydrothermal-magmatic systems of the Far East has been conducted to compensate for this gap.
