Preliminary report on the core drillings in the radioactive rocks of Kvanefjeld in the Ilímaussaq intrusion

Abstract

During the summer of 1969 seven core drillings were made on Kvanefjeld in the Ilímaussaq intrusion in an attempt to determine the geological relations of the U- and Th-bearing rocks (Sørensen, 1969). Prior to this investigation, 36 holes had been drilled in 1958 and 1962. A detailed geological map has been published (Sørensen, Hansen & Bondesen, 1969) and a series of surface radiometric investigations have been made in the area concerned.
