Mineralogical Study on High Aluminous meta-Claystone form the Chununsan Formation
천운산층내 고알루미나광석에 대한 광물학적 연구
Abstract
The high aluminous meta-claystones are thinly bedded to metasedimentary rocks which belong to Chununsan Formation. Major high aluminous minerals in the ores ae andalusite, kaolinite and pyrophyllite. The other significant constituents are sericite, chloritoid and carbonaceous material, etc. Ores can be classified into 4 types according to mineral compositions; andalusite- kolinite-sericite, andalusite-kaolinite-chloritoid, kaolinite-sericite-pyrophyllite, and kaolinite-chloritoid-sericite ore. The formation of ore minerals are resulted from sedimentary, diagenetic, metamorphic and hydrothermal processes. Andalusite are formed by low-grade metamorphism under the conditions of
