Resumé
Geochemical mapping by means of analysis of stream sediment and water collected at a density of 1 sample per 20-30 km2 has been carried out over part of the Archaean craton in the Maniitsoq region of West Greenland. The < 0 .1 mm fraction of the sediment samples was analysed by X-ray fluorescence and instrumental neutron activation techniques and results are reported for 41 major and trace elements. The conductivity and fluoride contents of the water samples were also determined.
The distribution of geochemical anomalies in the survey area indicates possibilities for: (1) gold mineralisation associated with noritic intrusions and shear zones; (2) chromium nickel mineralisation in dunitic rocks. One anomaly indicates a new occurrence of carbonatite or a related rock type.
