Abstract
The sampling of stream sediment for reconnaissance geochemical mapping has been completed for a large contiguous area from Uummannaq to Kap Farvel in West Greenland and the compilation of analyticaI data has commenced. Distribution patterns for the first two maps produced, those of calcium and potassium, outline provinces which are related to crustal features. The geochemical provinces can be interpreted to reflect differences in the depth of the exposed crustal segments. Geochemical boundaries occurring in geologically poorly known regions may be indicative of contacts between crustal blocks which have not previously been recognised. In the appendix the quality of the analytical data used in the compilation of the geochemical maps is documented, and the procedure of calibration between data sets is presented.
Highlights
The sampling of stream sediment for reconnaissance geochemical mapping has been completed for a large contiguous area from Uummannaq to Kap Farvel in West Greenland and the compilation of analyticaI data has commenced
Geochemical maps based on analysis of surface samples such as stream sediment, till or soil may reflect lithotectonic units and major crustal domains, as demonstrated by examples from Greenland and elsewhere (e.g. Plant et al, 1984; Steenfelt, 1987, 1990; McMillan et al, 1990)
In 1993 sampling and analysis of stream sediment for geochemical mapping have been completed over a 1200 km long contiguous area of West and South Greenland (Fig. l), and the compilation of data sets to produce geochemical maps of that area has commenced

The first part of this paper discusses the relation between the geochemical pattems and the exposed crustallevel of these domains; the appendix documents the quality of the stream sediment data and explains the calibration procedure
