Project SUPRASYD 1994 - Ketilidian supracrustal rocks in South-East Greenland and gold- bearing shear zones in the Julianehåb batholith

Abstract

The SUPRASYD project is a reassessment of the geo­tectonic setting and mineral potential of the Lower Proterozoic Ketilidian orogenic belt in southern Greenland (previously described by Allaart, 1976 and Kalsbeek et al., 1990), and in particular its supracrustal rocks. During the first field season in 1992 a geological and geochemical reconnaissance programme was carried out in South-East Greenland between approximately latitudes 60° to 62° N, mainly in areas with supracrustal rocks (Steenfelt et al., 1992; Nielsen et al., 1993; Chadwick et al., 1994a). The second season in 1993 focused on the southern part of the Julianehab batholith on the west coast of South Greenland, as well as on shear zones with spatially associated gold mineralisation (Garde & Schonwandt, 1994; Chadwick et al., 1994b; Stendal et al., in press). Field work from the early 1960s was re-evaluated and supplemented with new mapping with the aim of compilation of the 1: 100 000 scale map sheet 60 V.3, Sondre Sermilik.
