Geochemical mapping: distribution of gold, arsenic, antimony and tantalum in South Greenland

Abstract

New graphics software utilising raster techniques has been developed at the Geological Survey of Greenland (GGU) during 1989 and 1990 for presentation of geochemical and geophysical areal data. The software is very suitable for the display of the regional variation of chemical elements as contoured colour maps of interpolated data. In this paper we show the distribution patterns for a few selected elements of economic interest, which have been determined in stream sediment samples collected in South Greenland in 1979. The implications of the new information for the mineral potential of the region are briefly discussed.
