Cambrian Sm-Nd dates for an ultramafic intrusion and for high-grade metamorphism on the Øksfjord peninsula, Finnmark, North Norway / Mai Britt E. Mørk, Arne Stabel.
Title: | Cambrian Sm-Nd dates for an ultramafic intrusion and for high-grade metamorphism on the Øksfjord peninsula, Finnmark, North Norway / Mai Britt E. Mørk, Arne Stabel. |
Author(s): | Mørk, Mai Britt E. Stabel, Arne. |
Date: | 1990. |
In: | Norsk Geologisk Tidsskrift. (1990.), Vol. 70(4) (1990) |
Abstract: | Both well-preserved igneous rocks and thoroughly equilibrated meta-igneous rocks (granulites) were selected for dating of igneous activity and high-grade metamorphism. Metamorphic conditions correspond to high geothermal gradient situation. Intrusion of ultramafics may record termination of Late Proterozoic and possibly also Early-Mid Cambrian active rifting of Barents Shelf or Greenland lithosphere, while some of deformation at high-grade conditions may record transport of cooling palaeorift in Late Cambrian - Early Ordovician time. |
