dc.description.abstract | Within the mapped area slightly metamorphosed clastic sediments occur, probably of Upper Ordovician and Silurian age. The author describes a metagreywacke-slate association with metaconglomerates and gabbrodiorite sills, and a black-gray metasiltstone-slate association. Observations of preserved sedimentary structures, and microscopic investigations, indicate that these two associations are different sedimentary facies. The first consists of beds representing a flysch facies formed by turbidity currents. The second is a black shale facies developed in euxinic environments. The beds are strongly folded and the folds overturned to the east. Silurian deposits form the centre of a syncline which runs from the Kjøllhaugene area south through the mapped area. Regional metamorphism altered the sediments to the greenschist facies, and in part to the epidote-albite-amphibolite facies. | |
