    Abstract

    More than 800 stream sediments, soil, seepage soil and water samples collected during the field seasons of 1974 and 1975 in the Kap Franklin area, northern East Greenland, were analysed for K, Ca, Ti, Mn and Fe by radioisotope energy-dispersive X-ray fluorescence, and for U by delayed-neutron counting. Samples
    were also analysed for V, Cu, Zn and Pb by atomic absorption spectrophotometry.

    Areas with known mineralisation are outlined by anomalous Zn and Pb contents in stream sediments and soils. A predominantly mechanical dispersion mechanism is deduced from the similarity in the chemistry of bedrock, stream sediments and soils. Narrow dispersion halos following from this observation suggest that dense sampling procedures are required. The usefulness of Cu, Zn and Pb water geochemistry is not proved.

    There is reasonable agreement between a reconnaissance study and detailed investigations carried out in 1974 and 1975, respectively. The distribution patterns for Cu, Zn, Pb and U were more clearly displayed by means of the detailed sampling, and the metal contents in stream sediments were found to decrease rapidly downstream. Soil and seepage soil sampling between tributaries
    was shown to be advantageous. A test of daily and weekly variations of Cu, Zn and Pb in stream sediments of selected sampling sites demonstrated changes in the metal contents of generally less than 10 per cent.

    Data from soil samples in the Randbøldal clearly outline the extent of U mineralisation. There is good correlation between U, and Zn and Pb in both stream sediments and soils.
