We carried out the sensitive high resolution ion microprobe zircon U-Pb age dating and whole rock geochemical analysis of granites in the Gudambong and Sainam geosites, Danyang Geopark. The granites crop out in the western and southern parts of Danyang County, and intruded sedimentary successions of...

우리나라 화강암의 분포 현황은 어떠한가? | 화강암은 우리나라에서 가장 흔히 관찰되는 암석으로 경기육괴, 옥천대, 영남육괴, 경상분지 등 여러 지역에 걸쳐 다양하게 분포한다. 이로 인해 예전부터 석조 문화재 및 건축의 자재로 흔히 사용되었으며(Cho and Jwa, 2005; Kim et al. | |
옥천변성대 중부에 있는 속리산, 월악산, 무암사 화강암체가 동일 마그마 기원이라 주장된 근거는 무엇인가? | Lee et al. (2010)은 옥천변성대에서 산출하는 세 개의 백악기 화강암체에 대한 전암 Rb-Sr 등시선 연령, 지구화학 성분 분석 결과를 보고한 바가 있으며, 이들 화강암체들의 전암 연령과 지구화학적 유사성을 바탕으로 세 암체가 동일 마그마 기원임을 제시 하였다. 이들 세 암체 중 속리산 화강암체의 SHRIMP 저어콘 연령측정 결과는 94. | |
단양군의 특징은 무엇인가? | 연구지역인 단양군은 충청북도 북동부에 위치하고 있다. 단양군은 고원생대 기반암류, 고생대 퇴적암류, 중생대 퇴적암류와 화성암류들이 다양하게 산출하는 지역이다(Fig. 1b; Won and Lee, 1967). |
