Abstract
The ores of the Bobae mine are mainly composed of sericite and quartz, and with appreciable amount of some other minerals such as andalusite. pyrophyllite, and albite, etc.. Sericite occurs in various a1teration zones having different crystal size and habit. Sericites can be c1assified into two types based on the crystal size; fine-grained and coarse-grained sericite. Fine-grained sericite occurs as an aggregate. Mineralogical characterizations of both types of sericites have been studied with various methods. Lattice parameters of two types of sericites occurred in various alteration zones are almost identical. but b parameter of coarse-grained sericite appears to be slight1y bigger than that of fine-grained aggregates. Average structural formula of fine- and coarse-grained sericite is
보배광산의 광석광물은 주로 석영과 견운모로 구성되어 있다. 견운모는 이 광상의 각 변질대에서 산출되나, 그 정상에 의하여 조립질과 세립질로 구분된다. 각 변질대별 대표시료에 대한 결정광학적 특징은 유사하며, 단지 조립질 견운모의 경우 세립질 보다
