Mineralogy and Genesis of Hydrothermal Deposits in the South-eastern Part of Korean Peninsula:(2) Bobae Sericite Deposits
우리나라 동남부 지역의 열수광상에 대한 광물학적 및 광상학적 연구:(2) 보배견운모 광상
Abstract
Two illite polytypes, 2M1 and 1Md, have been identified from the sericite deposits of the Bobae mine, Kimhae, Kyungsangnam-do. Each polytype has characteristic grain size, chemical composition, and occurrence. 2M1 illite occurs predominantly in the sericitic alteration zone, while 1Md illite occurs predominantly in the propylitic alteration zone, implying that the former was formed in the higher temperature than the latter. Illites can be subdivided into two types based on their crystal sizes;(1) the
