Abstract
As part of a reconnaissance drainage sampling programme directed towards mineral exploration (Ghisler et al., 1979; Henriksen, this report), 318 samples of stream silt, collected in 1978, have been analysed for 18 elements by radioisotope excited energy-dispersive X-ray fluorescence and for U by delayed neutron counting. The results are used to describe the variation of element concentrations with respect to regional and lithostratigraphical changes in the Peary Land region. When these variations are known, anomalous concentrations of elements ean be distinguished and their significance evaluated with respect to possibie mineralisations.
Highlights
In dry arctic terrains the bedrock geochemistry is closely reflected by the chemistry of the sediment deposited in streams (Steenfelt & Kunzendorf, 1979)
The samples are sorted according to the chemical composition of the < 75 ""m grain size fraction
The groups II and III have been subdivided in order to investigate any regional or stratigraphical changes in the lithogeochemistry
Summary
In dry arctic terrains the bedrock geochemistry is closely reflected by the chemistry of the sediment deposited in streams (Steenfelt & Kunzendorf, 1979). C. Christensen Land (Jepsen et al, this report) is clearly outlined by the stream silt samples of this group C. Christensen Land the basalts are characterised by increased content of Cu, 98-114 ppm, as compared with the mean of 67 ppm Cu. Two samples from Mylius-Erichsen Land contain c.
