In the Jirisan area of the Yeongnam Massif, Korea, several ductile shear zones are developed within Precambrian gneiss complex (Jirisan metamorphic rock complex). The ductile shear zones have a general NS- and NNE-striking foliation with westward dipping directions. The foliation developed in the sh...

본 연구에서 지리산 변성암체 내에 발달하는 지질구조는 어떻게 나왔나요? | 본 연구에서는 지리산 변성암체 내에 발달하는 지질구조 가운데 특히 연성전단변형의 결과로 생성된 전단대 관련 구조자료들을 수집하였다. 노두 규모에서 수십 m~수십 cm의 폭을 가지는 전단대에는 전단엽리면과 함께 특정 방향의 신장선구조와 전단감각이 관찰된다. | |
영남육괴는 무엇인가요? | 영남육괴는 경기육괴, 낭림육괴와 함께 한반도의 기반을 이루고 있으며, 주로 선캄브리아시대의 암석들로 구성되어 있다. 영남육괴는 북서쪽으로 옥천대와 남동쪽으로 경상분지와 경계를 이루며 예천전단대 혹은 안동단층의 서쪽 연장을 경계로 하여 북동부의 소백산(혹은 태백산)지구와 남서부의 지리산(혹은 덕유산)지구로 구분된다(Kobayashi, 1953; Kim and Park,1980)(Fig. | |
지리산지구는 어떻게 구성되어있나요? | 지리산지구는 지리산 동측을 따라 남북으로 발달된하동-산청 회장암 복합체를 경계로 서쪽은 상부-앰피볼라이트상 내지 그래뉼라이트상에 이르는 고도 변성작용을 받은 선캄브리아시대 이질 내지 사질 편마암과 고기 화강편마암류들로 주로 구성되어 있다(Lee,1980; Lee et al., 1981). |
