Large scale geochemical variation in the Precambrian of West and South Greenland

Abstract

Reconnaissance geochemical mapping by means of stream sediment and water has been carried out by the Geological Survey of Greenland (GGU) in West and South Greenland since 1979 (Steenfelt, 1987, 1993). The aim of the programme is to evaluate the potential for mineral resources. The geochemical data are used in two ways: (1) to identify chemical anomalies indicative of mineralisation; and (2) to contribute to the recognition of environments favourable to ore deposition. However, when compiled over large areas the data also permit a distinction to be made of large scale crustal domains.
