Record #107410:

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.
