Detailed ground magnetic survey in the central part of the Sarfartôq carbonatite complex, southern West Greenland

A detailed ground magnetic survey was carried out by the authors and Egon Hansen, electronics technician, during the spring of 1981 in the central part of the Sarfart6q carbonatite complex near Søndre Strømfjord. It was important for the survey that there was continuity of measurements over the whole area, and as most of the area was covered by swamp in the bottom of the valley Arnangarnqup kua, it was most convenient to make the survey when the surface was frozen.
