Abstract

The geology of Greenland is dominated by crystalline rocks of the Precambrian shield, which mainly formed during an Archaean and early Proterozoic orogenic events. In the Archaean period, the gold and banded iron formations formed in granite-greenstone terrane in southern West Greenland. Ultramafic to mafic intrusions belts occurs in Greenland as major carriers of Cr-Ni-V. In the Palaeoproterozoic period, the gold deposit as Nalnuaq hosted in Ketilidian orogen belt and Sedimentary exhalative (SEDEX) lead-zinc deposits as Black Angle are hosted in the Palaeoproterozic marble of the Karrat Group. In the early Mesoproterozoic Era, Gardar Province in Southern Greenland hosts several major magmatic hosted REE mineral deposits, e.g. the Motzfeldt nepheline syenite complex strongly enriched in Zr-Ta-Nb-REE-U-Th, and the Ilimaussaq intrusion enriched in F-Zr-Zn-REE- Y-U-Th in the southern Greenland. Palaeogene layered tholeiitic gabbro complexes is well-known in East Greenland and the Skaergaard intrusion is associated with Pd, Pt, Au and Cu mineralization.

그린란드 지질은 주로 시생대와 초기 원생대 조산운동 시 형성된 선캠브리아 순상지 결정질암이 우세하다. 금과 호상철광층은 남서부 지역 시생대의 화강암-녹색암 층에서 형성되었다. 고기 원생대의 금광상이 Nalnuaq지역 Ketilidian 조산대에서 나타나고 있고, 퇴적 분기성 연-아연광상인 Black Angle광상은 Karrat Group의 대리암내에 배태된다. 중기 원생대에 주요 마그마 기원의 희토류 광상이 그린란드 남부 Gardar지역에 많이 나타난다. 즉, 그린란드 남부에 모젯펠트 하석질 섬장암 복합체는 Zr-Ta-Nb-REE-U-Th, Ilimaussaq 관입암은 F-Zr-Zn-REE-Y-U-Th가 부화되는 암체들이다. 동 그린란드의 스캐가르드 관입암은 고 제3기의 층상 하석질 반려암 복합체로서 Pd, Pt, Au, Cu등 광화작용을 수반하고 있다.
