Structural evolution of the Bergsdalen Nappes, Southwest Norway
(NGU Bulletin (424), Journal article, 1993)The Bergsdalen nappes are Caledonian thrust sheets which experienced perva- sive, although heterogeneous ductile deformation during the upper green- schist to lowermost amphibolite-facies, Caledonian, thrusting history. ... -
Structural history of the Bygdin area, Oppland.
(NGU (247), Journal article, 1967)The tectonic history of the area, which is part of the marginal thrust zone of the Norwegian Caledonides, is described. Within the area, the Upper Jotun Nappe has been thrust over the Valdres Sparagmite and the Bygdin ... -
Structural interpretation of a double-folded gneiss-amphibolite sequence, Bunnefjorden, Akershus.
(NGU (300), Journal article, 1973)Garnet amphibolite bands folded together with gneiss lamellae in tight to isoclina folds are described. A structural analysis shows that the folds were formed during two separate deformation episodes. This conclusion has ... -
Structural mapping of potential rockslide sites in the Storfjorden area, western Norway: the influence of bedrock geology on hazard analysis
(NGU-Rapport (2006.052), Report, 2006)Forkortet:\rThe western coast of Norway is particularly vulnerable to active rockslide development due to the recent post-glacial uplift and the deep incision of the fjords created by glacial activity, leading to extremely ... -
Structural mapping of the Åknes Rokcslide, Møre and Romsdal County, Western Norway
(NGU-Rapport (2008.042), Report, 2010)Åknes is known as the most hazardous rockslide area in Norway at present, and is among the most investigated rockslides in the world, representing an exceptional natural laboratory. This study focuses on structural geology ... -
Structural observations from the Kopperå-Riksgrense area and discussi- on of the tectonics of Stjørdalen and the N.E. Trondheim region.
(NGU (245), Journal article, 1967)Minor tectonic structures occurring in weakly metamorphosed Hovin and Horg Group sediments along Tevedalen, east of Meråker, are described in the first part of the paper. Three episodes of folding are recognized, the ... -
Structural setting of two Mesozoic half-grabens off the coast of Trøndelag, Mid-Norwegian shelf
(NGU Bulletin (427), Journal article, 1995) -
Structural succession in a part of the outer Hardangerfjord area, West Norway.
(NGU (343), Journal article, 1978)Recent mapping has made possible a reinterpretation of the tectonostratigraphy of this area, situated at the eastern edge of the \"Faltungsgraben\". It is shown that certain rock units occuring over large areas, and formerly ... -
Structure and evolution of the Atlantic floor between Northern Scotland and Iceland.
(NGU (316), Journal article, 1975)The continental shelf west of the Shetland and Orkney islands is a region of varied geology traversed by the Caledonian front, including some areas of shallow basement and some partially fault-bounded Mesozoic basins such ... -
Structure and petrology of the Bergen-Jotun kindred rocks from the Gjendebu region, Jotunheimen, Central Southern Norway.
(NGU (373), Journal article, 1982)The Gjendebu region is located within the Jotun Nappe, highest tectonic unit of the southern Norwegian Caledonides. The structure of the area is dominated by the NE-rending Tyin-Gjende Fault, a major zone of repeated ... -
Structure of the Jotun Nappe Complex, Southern Norwegian Caledonides: Ambiquity of Gravity Modelling and Reinterpretation.
(NGU-Rapport (89.169), Report, 1990)Gravity studies have previously indicated a deep root zone (16 kmthick) below the outcropping pyroxene-granulites of the Jotun Nappe Complex in Norway. Combined interpretation of gravity and aeromagnetic data give re- sults ... -
Structure, mineralogy, chemistry and economic potential of calcitic marble in the Geitfjellet-Bukkafjellet area, Nord-Trøndelag
(NGU-Rapport (93.043), Report, 1993)Forekomstene av kalkspatmarmor i Geitfjellet-Bukkafjellet-området sørvest for Grong i Nord-Trøndelag representerer en sammenfoldet avsetning som hører til bergarter i Svedekket. Marmoren er en ren og grovkornet kalkspatmarmor ... -
Structures and metamorphism at Brygfjell-Simafjell within the Rødingsfjellet Nappe Complex, Nordland, Norway
(NGU Bulletin (431), Journal article, 1996)Structures and metamorphic featues are described from parts of the area of 1:50 000 map-sheet Korgen. The area investigated is situated within the Rødings- fjellet Nappe Complex in the Caledonides of Nordland. The rocks ... -
Structures and ore genesis of the Grimsdalen deposits, southern Trondheim region, Norway.
(NGU (351), Journal article, 1979)The central part of the Grimsdalen area of the southern Trondheim region is occupied by a sequence of metavolcanics with subordinate metasediments, termed the Folla Group, which are correlated with the Støren Group of the ... -
