Review of the Survey's activities in 1978

Abstract

The main field activity of the Survey in 1978 was a study of the geology of North Greenland (fig. 1). This was the first summer of a three year project which aims at a geological synthesis of the whole region together with the compilation of two 1:500000 geological maps. Significant additions to the geological knowledge of the area included the discovery ol an extensive Proterozoic basalt province, an extension of the known distribution of the late Proterozoic to Silurian strata, and of the late Palaeozoic to Tertiary Mesozoic sequences of the Wandel Sea Basin. The field work has been undertaken in cooperation with the Geodetic Institute, establishing a set of ground central points for the preparation of topographic maps of northern Greenland. These maps will be based on a new set of aerial photographs which were taken during the summer. The Danish Air Force using a Hercules aircraft flew in the group of 32 geologists and surveyors and their equipment to Station Nord. Geological studies and surveying went according to plan, in spite of more snow cover than usual in most of Peary Land.
