A study on Talc mineralization of Serpentine

Biggest talc deposits of South Korea, localized in Choong-Chung-Nam-do, are known as a products of hydrothermal metamorphism of serpentine. From studying mineral paragenesis and localization, three types of talc mineralization is presumed as follows: 1) Extended talc mineralization from autometamorphism (serpentinization) of ultra-basic igneous rocks, 2) Schistose talc rock as green schist facies of regional metamorphism and 3) Late hydrothermal mineralization and purification of serpentine and pre-existing low grade ores.
