Various studies regarding the sedimentary environment, depositional age, provenance, and metamorphic history have been carried out on the Taean Formation in the western part of Gyeonggi Massif, since the unique detrital zircon age pattern was revealed. This review paper introduces the previous resea...

태안층의 구성은? | 태안층은 전통적으로 선캠브리아시대의 지층으로 알려졌으나, 근래 다수의 전기-중기 고생대 저어콘들이 발견된 이후 중부 혹은 상부 고생대 퇴적층으로 해석되고 있다. 태안층은 주로 석영과 운모로 구성된 변성사암, 이질편암, 천매암으로 구성되었으며, 이들의 원암은 심해선상지의 로브 환경에서 쌓인 저탁암으로 해석되었다. 태안층이 퇴적된 시기는 쇄설성 저어콘 연령과 관입암의 연령 차이를 통해 데본기-트라이아스기 사이로 알려져 있는데, 퇴적시기가 데본기에 가깝다는 견해와 페름기에 가깝다는 견해로 나뉜다. | |
