Geological investigation of a lower tertiary/quaternary core, offshore Trøndelag, Norway.
Abstract
Seismic profiling carried out offshore Trøndelag, Norway, has provided a basis for selecting localities for core sampling of the bedrock. A continous, metre-long core revealing new information was recorded. Sedimentological, mineralogical, geotechnical and micropaleontological investigations indicate that the core consists of near-shore, silty claystone of Upper Cretaceous\/Lower Tertiary age at the base, of Quaternary till in the middle, and of Late Quaternary cover sand at the top.
