Rare-earth element distribution patterns in metasomatites of Eastern Kazakhstan gold-ore deposits

Abstract

The article describes the distribution patterns of rare-earth elements in metasomatites of Eastern Kazakhstan gold-ore deposits. The results demonstrated that the formation of all metasomatites is associated in the rebalancing process of rare-earth elements. The investigation established the vertical differentiation of rare-earth elements in beresites accompanying gold-ore mineralization of various structural and morphological types. Three types of distribution of rare-earth elements in wallrock beresites have been identified.
