Notes on the glacial geology of eastern Milne Land, Scoresby Sund, East Greenland

Abstract

During the summer of 1969 field work was begun with the aim of establishing a general chronology of Quaternary events in the Scoresby Sund region. This summer the work was concentrated on the eastern part of Milne Land (fig. 1). The region under consideration is shown in fig. 9; it comprises a coastal zone of low rounded mountains (400-600 m) composed of crystalline rocks, and a central zone of high mountains (1500 m) of alpine topography where Tertiary basalts rest on a basement of crystalline rocks. South-east of a line from Mudderbugt to Charcot Havn the bedrock is Mesozoic sandstone. Milne Land is bordered to the east and south by the comparatively shallow (400-600 m deep) waters of Scoresby Sund and Hall Bredning; on all other sides this large island is bordered by over-deepened fjords (800-900 m deep - see hydrographic chart in Thorson, 1934). In the central part of Milne Land an ice cap - Puderne - is found.
