Investigations on the Precambrian rocks of Svartenhuk Halvø, central West Greenland

Abstract

Precambrian rocks occur within an area of 600 km2 in eastern Svartenhuk Halvø. A preliminary geological account of the southern half of this area is given here. The work is part of the mapping programme aimed at the production of the l: 100 000 sheet 71 V. 1 N. The Precambrian rocks east and south of Svartenhuk Halvø have been studied in some detail by Henderson & Pulvertaft (1967), but until the summer of 1981, apart from the pioneering work of Steenstrup (1883) and preliminary petrographic descriptions of the metasediments by Noe-Nygaard (Rosenkrantz et al., 1942), the Precambrian of Svartenhuk Halvø had only been studied in the detail necessary for the production of the l:500000 map sheet Marmorilik - Melville Bugt. The map area consists of a gneissic basement with a metasedimentary cover (fig. 6).
