Pleistocene and recent sediments of the Norwegian Continental Shelf (62°N-71°N), and the Norwegian Channel area.

Abstract

The surface sediments covering the area under consideration can be divided into 4 groups: 1. Till, mainly composed of material derived from the adjacent mainland. 2. Till, mainly containing material derived from Mesozoic-Tertiary bedrock on the continental shelf. 3. Lag deposits from 1 and 2, mainly in shallow areas. 4. Secondarily transported sand and finer material winnowed out from 1 and 2, probably partly mixed with meltwater deposits, and deposited at intermediate and greater depths. There is a clear relationship between depth and sediment texture. The thickness of post-Tertiary sediments varies between 0 and 400 m. In areas with thin cover, the glacial sediments have a lithology greatly influenced by the subsurface rocks.
