Preliminary report on the stratigraphy of the Precambrian and Eocambrian sediments in the Jørgen Brønlund Fjord – Midsommersø area, southern Peary Land

Abstract

As a member of the 5th Danish Peary Land expedition led by Eigil Knuth, the author carried out geological field work in an area bounded by Jørgen Brønlund Fjord (82°10' N, 30-32°W), Midsommersø (82°15' , 33-36°W) and Inuiterk Sø (82°, 35°W). The same area was visited in 1966 (Jepsen, 1966) with the main object to study the intrusive rocks. In the summer of 1968 the purpose was partly to study the stratigraphy of the sediments and partly to get a better understanding of the nature of the intrusive rocks. In this note it is mainly the first problem, viz. the stratigraphy of the sediments, that will be discussed.
