(The) study on the fossil assemblages from the Kimpo group, Kimpocoalfield and their stratigraphic significances

open access: yes, 1985
본 연구에서는 김포탄전지역의 퇴적상을 조사하고 이 지역에서 산출되는 고생물학적 자료를 통해 김포탄전의 층서를 연구하고 이에 대비되는 한반도내 타지역의 초기 중생대층군과의 대비를 연구하였다. 김포탄전지역에는 Precambrian의 변성암, 중생대화강암, 중생대퇴적암들이 발달한다. 중생대 퇴적층은 하부층인 통진층과 상부층인 문주산층으로 나누어진다. 통진층은 주로 셰일층으로 이루어져 있으며 사암, 역암등이 협재되어있고 층후는 800미터이다.
