New field investigations of the Ilímaussaq kakortokite

Abstract

The summer season of 1968 was spent at Kangerdluarssuk where detailed investigations of the stratigraphy of the layered kakortokite, first described by Ussing (1912), were made. It is intended that this work should form the basis for detailed petrological and geochemical investigations aimed at gaining some insight into the mechanisms of formation of this remarkable series of igneous cumulates which has aIready been studied in some detail by Ferguson (in press).
