... within the Storelv Gabbro should be reassessed in the light of the age dating reported below. More recent Sm–Nd geochronology resulted in a complicated scenario for the evolution of the Finnmark region. In a paper incorporating numerous studies on the area, Daly et al. (1991) provided ages...

Here, we use Sr and C isotope chemostratigraphy to constrain the depositional age and, by analogy with other parts of the Scandinavian Caledonides, the provenance of a regionally extensive marble...

... on the origin and timing of metamorphism of these nappes. We discuss their potential derivation, time of emplacement, and metamorphism. The geology of the Finnmark region is dominated by three main elements: (1) the basement of the Baltic Shield with its generally thin autochthonous sedimentary cover...

Although it is widely accepted that D 2 was responsible for the main regional schistosity (S 2 ) ( Gayer et al . 1985 ), it is often impractical to distinguish F 2 folds from later F 3 structures because the two sets...

... the Baltic Shield. These nappes have been correlated regionally (Fig. 1) and comprise the uppermost Mager~y Nappe, the underlying Kalak Nappe Complex, the Laksefjord Nappe Complex and the Gaissa Thrust Belt (Roberts 1985, Gayer et al. 1987). The last unit rests in thrust contact with an autochthonous Late...

...F. Corfu; T.H. Torsvik; T.B. Andersen; L.D. Ashwal; D.M. Ramsay; R.J. Roberts Abstract The Caledonian Magerøy sequence comprises Earliest Silurian clastic metasedimentary rocks, which underwent folding and regional metamorphism and were intruded by a mafic–ultramafic complex and various granitic...

..., which resulted from major plate reorganization in the Paleozoic and is associated with the Caledonian-Appalachian Orogen. Neoproterozoic-age magmatism and deformation events are known from many allochthonous sequences in the North Atlantic region (Daly et al. 1991 ; Rogers et al. 1998 ; Watt...

... at a depth of 20-30 km within the crust. An independent investigation by Sturt & Taylor (1972) on the nearby island of Soroy (Fig. I) has shown that the synorogenic Storelv gabbro crystallized under regional pressures of 7-9 kb, a figure in fair agreement with the data given here. The emplacement of a high...

The minimum value of the integrated conglomerate strain consisted of 65 per cent vertical shortening, a transverse NW elongation of 160 per...
