The structure and regional setting of the Skei Group, Leka, north-central Norway
(NGU Bulletin (426), Journal article, 1994)The unconformity between the metasedimentary Skei Group and subjacent ophiolite on Leka has important implications for the tectonostratigraphy of the region. As a distinctive marker horizon, it permits correlations within ... -

The structure of Mellene and Heggberg, Valdres.
(NGU (243C), Journal article, 1967)Structural study of the Valdres Sparagmite and Mellsenn Formation in their type region between the Jotunheim crystalline rocks and the frontal quartzite nappes of the central southern Norwegian Caledonides has revealed ... -
The structure of the Magerøy Nappe, Finnmark, North Norway.
(NGU (363), Journal article, 1981)The Magerøy Nappe was emplaced during the Scandinavian phase of the Caledonian orogeny, of Middle\/Upper Silurian age. Two main episodes of deformation (D1 and D2) with attendant Barrovian-type regional metamorphism are ... -
The style of deformation in the Devonian rocks on Hitra and Smøla, Central Norway.
(NGU Bulletin (414), Journal article, 1989)The Old Red Sandstone sequence in the Outer Trøndelag Region comprise conti-nental conglomerates, sandstones and mudstones of latest Silurian to MiddleDevonian age. During a Late Devonian tectonic phase (Solundian Phase) ... -
The sub-Caledonian unconformity on Hjelmsøy - new evidence of primary basement/cover relations in the Finnmarkian nappe sequence.
(NGU (351), Journal article, 1979)A new and important occurence of a primary stratigraphic unconfomity beneath tha Caledonian cover in allochthon of the Finnmarkian segment of the North Norwegian Caledonides is described. This unconformity, on the island ... -
The sulphide deposit of Nordre Gjetryggen Gruve, Folldal, Norway.
(NGU (228), Journal article, 1964)Nordre Gjetryggen Gruve in the Folldal district, southern Norway, is at approximately 62 9'N. latitude and 10 E. longitude. The mining of copper from pyritic ores began in the area in 1748, while the recovery of zinc and ... -
The surface of the inland ice in the Atndalen valley, South-central Norway.
(NGU Bulletin (438), Journal article, 2001)On the basis of different field observations, several authors have discussed the form of the inland ice in southern Norway. In this work, lateral features indicating the upper limit of zones of meltwater drainage marked ... -
