Mineralisations in the Malene supracrustals in the Godthåb area, West Greenland

Abstract

The geology of the Godthåb area, West Greenland, has been studied for several decades, mainly by the Geological Survey of Greenland (GGU), but also by groups from British and other Universities. This work has resulted in a detailed understanding of most of the major rock forming events which have affected the area. However, one important aspect af the geology has been largely negleeted in the previous work, that is the metal!ogeny of the rock units in the area. Mining companies have undertaken only scattered work in the area, e.g. on the molybdenite mineralisation in Narssaq, south of Godthåb. It was therefore decided to launch a reconnaissance study of the mineralisations of one of the major rock units, the Malene supracrustals. Rather detailed work was carried out on Qilángarssuit, Sagdlerssua and Simiutat, while Narssaq, Angissunguaq and Mitsimavissuaq were visited for a short period only.
