Summary
In the first part of the report, a synopsis is presented of the general geology and tectonostratigraphy of this part of Central Norway, with a slightly more detailed account given of the geology of Fosen Peninsula. The second part comprises an excursion guide, spanning 3 days, covering the southern district of Fosen from Rørvik to Ørland and to the outer coast near Sandnes; and then continuing along the Verran Fault (Møre-Trøndelag Fault Complex) via Verrabotn and Beitstadfjorden to Steinkjer. The last day of the excursion takes in selected localities along the southeastern side of Trondheimsfjorden, finishing at Storvika close to Trondheim airport Værnes. The excursion aims to show the variety of rock-types at different tectonostratigraphic levels in this part of the Caledonides, and demonstrates the significance of faulting and diversity of fault trends, fault rocks and vein systems of a variety of ages in this onshore region adjacent to the Mid-Norwegian continental shelf. A preliminary version of this report and guide was distributed to participants during the actual excursion, 2-4 September 1998 - days blessed by warm, sunny weather. The excursion was the first in the project "Basin analysis and applied thermochronology on the Mid-Norwegian Shelf", otherwise known as the "BAT project".
