Description

One major goal is to create a model for long-term landform development specifically in basement rocks. A second major goal is to understand which features in previously glaciated areas that are inherited from preglacial landscapes. There are three data sets of special importance for understanding long-term landform evolution in the basement, viz. the landforms per se, the surrounding sedimentary record, and thermochronology of the bedrock. We use the landforms and relate them to the other data by co-operation with geologists and geophysicists. The landforms are studied in different scales in the field, in aerial photos and in Digital Elevation Models. After support from NFR/VR during 20 years I am now to finish my salaried research carrier by synthesising results and indicating possibilities for future research by the use of new tool combinations. Three major themes are treated: 1) A reconstruction of uplift and landform development along the Atlantic passive margins of Scandinavia, West Greenland and Canada by the use of reference surfaces and fluvial valley patterns. 2) A reconstruction of relief genesis within the Laurentian shield in Canada and Greenland through an anlysis of the relation between forms and weathering remnants in the basement on the one hand and the sedimentary covers on the other. 3) A quantification of glacial erosion in basement rocks as estimated from the difference in form between present relief and identified reference surfaces.
