Brittle deformation history of fault rocks on the Fosen Peninsula, Trøndelag, Central Norway.
(NGU Bulletin (421), Journal article, 1991)Late and post-Caledonian fault deformation of rock units on the Fosen Peninsula follows a time sequence wherein lower crustal ductile deformation was followed by several episodes of brittle fragmentation, some with coeval ... -
Depth of extensional faulting on the Mid-Norway Atlantic passive margin.
(NGU Bulletin (437), Journal article, 2000)Two crustal-scale cross-sections of the Mid-Norwegian Atlantic passive margin are discussed. Large W- and E-dipping normal faults relate to extension of the continental crust following the Caledonian orogeny and the ... -
Grunnfjellet omkring Tangen, østsiden av Mjøsa.
(NGU (211), Journal article, 1960)Petrographic and structural investigations were made in a Precambrian area east of lake Mjøsa, southern Norway. The rocks, mainly granitic and dioritic, are mostly mylonitised and brecciated. Some of the fault zones are ... -
