The geochemistry of stream silt, North Greenland

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.
