Dating explosive volcanism perforating the Precambrian basement in southern Norway.
Andriessen, P.A.M.; Boelrijk, N.A.I.M.; Hebeda, E.H.; Verschure, R.H.; Priem, H.N.A.; Verdurmen, E.A.Th.; Maijer, C. (NGU (380), Journal article, 1983)K-Ar and Rb-Sr dating have been performed on various hypabyssal diatreme-facies volcanic rocks perforating the Sveconorwegian zone of the Precambrian basement in southern Norway. The dated rocks were taken from the Fen ... -
Isotopic age determinations in South Norway: II. The problem of errorchron ages from Telemark rhyolites.
Maijer, C.; Verschure, R.H.; Andriessen, P.A.M. (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 ... -
Metamorphic petrology of the Froland corundum-bearing rocks: the cooling and uplift history of the Bamble Sector, South Norway
Nijland, T.G.; Visser, A.; Maijer, C.; Visser, D.; Liauw, F. (NGU Bulletin (424), Journal article, 1993)Corundum-bearing rocks from Kleggåsen, Froland, preserve metamorphic textures which reflect the cooling and uplift path of the Bamble Sector. The P-T path may be correlated with a T-t path constructed from published ages. ... -
Polyphase Caledonian metamorphism in the Precambrian basement of Rogaland/Vest-Agder, SW Norway.
Hermans, G.A.E.M.; Jansen, J.B.H.; Maijer, C.; Spits, P.; Wegelin, A.; Sauter, P.C.C. (NGU (380), Journal article, 1983)In the Sveconorwegian basement of Rogaland\/Vest-Agder, SW Norway, two incipient Caledonian metamorphic overprints are assumed on the basis of petrological textures and regional extension of the metamorphic mineral ...
