The chemistry of the Fiskenæsset complex on Qeqertarssuatsiaq

Abstract

Rock and mineral analyses arranged in stratigraphic order through the Fiskenæsset complex provide a basis for discussing its geochemistry, a summary of which is given here. Eighteen XRF whole rock analyses made at Leeds University have been used by Windley, Herd & Bowden (in press) to determine the way-up of the intrusion and to provide preliminary bulk geochemical trends. One hundred and twenty eight mineral analyses made with the ARL electron probe at Chicago University by Windley & Smith (in press) have been used to determine cryptic variation trends in the intrusion and to establish distribution pattems of elements within major phases and between coexisting phases.
