국내 장석 광상의 성인 및 유형: 제천 및 부여광산 = Type and Origin of The Domestic Leading Feldspar mines: Jecheon and Buyeo mine

다국어 초록 (Multilingual Abstract)

A type and origin of Buyeo and Jecheon mine as the domestic leading feldspar mines are classified by using the petrological characteristics. Jecheon mine is a weathered residual mine formed by the weathering of K-feldspar megacryst bearing porphyritic granite of which forming P-T is 840℃-5Kb with the igneous origin of megacryst. On the other hand, Buyeo mine is made by the metasomatic alteration of hydrothermal solution from the biotite granite intrusion. Pure albite as a main ore mineral and garnet and sericite as accessaries are observed in this mine. In addition, the mine is typically characterized by the well recrystallized mineral texture.

국내 대표적인 장석광상인 제천장석 광산과 부여장석 광산 모암의 암석학적 특성을 통하여 국내 장석광의 성인 및 광상유형을 분류하였다. 제천장석 광산은 거정질의 K-장석을 함유한 반상화강암이 풍화되어 잔류물로 나타나는 거정질 K-장석이 채취대상이 되는 전형적인 풍화잔류 광상이고 반상화강암의 형성 온도-압력은 840℃, 5Kb를 나타내며 거정질의 K-장석은 변성기원이 아닌 화성기원이다. 반면 부여장석 광산은 우백질 화강편마암이 주변의 흑운모화강암의 관입으로 열수용액에 의한 교대변질 광상으로 순수한 알바이트 장석과 부수광물로서 석류석, 견운모가 나타나며 치밀하게 재결정화된 광물조직이 특징이다.
