Deep Structure of the Mid-Norwegian Shelf – Insight from Potential Field Data

P163 DEEP STRUCTURE OF THE MID-NORWEGIAN SHELF – INSIGHT FROM POTENTIAL FIELD DATA 1 J.R. SKILBREI O. OLESEN and P.T. OSMUNDSEN Geological Survey of Norway N-7491 Trondheim Norway Summary: Aeromagnetic and gravity data sets for the Mid-Norwegian shelf and mainland Norway have been interpreted in terms of basement structures and land to offshore tectonic links. We have produced maps of the depth to the top of the crystalline basement of the depth to the' Base of the Cretaceous' and a map of the 'pre-Cretaceous sedimentary thickness'. From the estimated basement map a pattern of basement highs/horsts and basins emerges that
