New mapping in north-western Disko 1972

Abstract

During the summer of 1972 the areas around Hammers Dal and Rinks Dal, north-west Disko were mapped. Special emphasis was laid on the investigation of the contaminated volcanic rocks and related intrusives occurring within the area, and on establishing the structural pattern, fundamental for the interpretation of the offshore geology. The area investigated was previously only poorly known. Short accounts have been published by Miinther (1951) and Pedersen (1969). Some general remarks were made by Miinther (1973). A structural interpretation based on a photogeological study has been given by Henderson (1973) and a geological map based on earlier work by GGD before 1968 has been compiled by V. Miinther (unpublished map sheet). The western part of the area, facing the Davis Strait, is a poorly exposed lowland. Further east the land surfaee forms a gradually rising plateau disseeted by valleys and the area becomes better exposed.
