New investigations of the native iron bearing volcanic rocks of Disko, central West Greenland

Abstract

A reinvestigation of the native iron bearing rocks of northern Disko has been initiated as a follow up of new regional mapping. A variety of hypotheses as to formation have been put forward since the work of Steenstrup (1882a); a bibliography is given by Bøggild (1953) and a recent review by Pauly (1969). In addition to examination of the nature of the deposits as such, the purpose of the new investigations is twofold. (1) To map the native iron bearing volcanic rocks which ean be used as stratigraphical marker horizons. (2) To investigate the possibie economic potential of segregations of native iron and sulphides found in these rocks.
