Observations on the Quaternary geology of the Rødefjord region, Scoresby Sund, East Greenland

Abstract

During the summer of 1970 mapping of Quaternary geology was carried out in the inner part of the Scoresby Sund fjord complex in an area extending from Rypefjord and Harefjord through Rødefjord and Fønfjord to Gåsepynt (map 3). The rock types in this part of the Scoresby Sund area are mainly crystalline rocks of Caledonian and pre-Caledonian origin forming high mountain plateaus with gently undulating surfaces 1500-2000 m above sea level and with independant ice caps. A post-Caledonian red conglomerate occurs in areas along Rypefjord, Harefjord and Rødefjord; due to the easy erosion of this rather loose sedimentary rock it now occurs as areas of smooth lowland.
