(NGU (382), Journal article, 1983)A general account is presented of the field relationships, geochemistry and petrology of mafic and ultramafic metavolcanics within the Precambrian Karasjok greenstone belt. These metavolcanic rocks make up the major part ... -
Isotopic age determinations in South Norway: II. The problem of errorchron ages from Telemark rhyolites.
(NGU Bulletin (418), Journal article, 1990)Two sets of Telemark Supracrustal acid metavolcanics of the Rjukan Group were investigated by the Rb-Sr whole-rock method. Eleven smples within a sampling range of about 10 m were taken at Kvamsstøl at a distance of about ... -
Late Quaternary geological development of the Jutland Bank and the initiation of the Jutland Current, NE North Sea
