New investigations of Tertiary lavas and dykes in the area around Disko Fjord, central West Greenland

Abstract

The purpose of the summer's field work was twofold: (a) to search for native iron and sulphide mineral assemblages in the northem extension of the Kitdlit dyke (Fundal, 1975; Pedersen, 1977a & 'a' in figs 10 & 11) and other related (sediment contaminated) dykes, and (b) to map the surrounding area as a contribution to the map sheet Diskofjord (69 V. 1 N, fig. 2). About 600 km2 were mapped in detail and 1500 km2 briefly surveyed.
