Quaternary deposits around Holsteinsborg

Abstract

The area investigated in 1967 is situated between 66°20' and 67°10' N. 52°30' and 54°W. and is part of the high outer coastal terrain of central West Greenland. The greatest heights - more than 1000 m - are seen in the northernmost and southernmost parts of the area. These parts are separated by an E-W-running depression around Ikertoq fjord. the western continuation of which is seen offshore in Holsteinsborg Dyb (the Holsteinsborg trough), a submarine canyon 500 m deep separating Store Hellefiske Banke from Lille Hellefiske Banke. Whilst the banks are thought to be ice margin deposits which accumulated during the ice ages, the Holsteinsborg trough acted during these times as a drainage channel for the Inland Ice.
