The Precambrian geology of Vest-Finnmark, Northern Norway.
(NGU (201), Journal article, 1957)Det undersøkte området har sin naturlige geologiske grense inord langs \"Hyolithussonen\". I syd danner riksgrensen mot Finlandgrensen for undersøkelsenen og i vest er området begrenset avfylkesgrensen mot Troms. Området ... -
The precambrian metamorphic rocks around the lake Vegår (Aust-Agder, southern Norway).
(NGU (257), Journal article, 1968)An area about 2000 km between the Skagerak coast (Tvedestrand - Risør) and the Southern part of the Telemark province (Tjønefoss - Neslandvatn) has been investigated and is considered to be a genetically homogenous migmatitic ... -
The structural and metamorphic history of the Langstrand-Finfjord area, Sørøy, Northern Norway.
(NGU (253), Journal article, 1968)The Langstrand-Finnfjord area of N.E. Sørøy is characterised by a metasedimentary sequence of quartzites, pelitic and semi-pelitic schists and limestones, the stratigraphical order of which can be demonstrated by reference ... -
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 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 Surna, Rinna and Orkla Nappes of the Surnadal-Orkdal district, southwestern Trondheim
(NGU Bulletin (418), Journal article, 1990)In the district between Surnadal and Orkdal within the 'Gula', the rock sequence between the Late Precambrian metasandstones of the Tingvoll Nappe and assumed Lower Ordovician metavolcanites of the Støren Nappe, three major ... -
The Tectonostratigraphy and structural evolution of the Sitas Area, North Norway and Sweden (68°N).
(NGU Bulletin (416), Journal article, 1989)The Sitas area contains rock derived from the pre-Caledonian Scandinavian craton and from an accreted Caledonian fore-arc complex. These rocks form the par-authocthonous (?) Rombak Complex which can be tied stratigraphically ... -
Utilisation of sillimanite minerals, their geology, and potential occurrences in Norway - an overwiev
(NGU Bulletin (436), Journal article, 2000)The aluminium-silicate polymorphs sillimanite, andalusite and kyanite decompose to a mixture of mullite and silica glass during calcination. Mullite is an essential component of high-alumina refractories forming the inner ... -
Velfjord. Beskrivelse til det berggrunnsgeologiske gradteigskart I 18 - 1:100 000.
(NGU; Skrifter (274; 1), Journal article, 1972)The various lithologies are described. These comprise granitic basements rocks of supposed Pre-Cambrian age and Cambro-Silurian supracrustals and intrusives. The intrusives are mostly found within the Bindal and Velfjord ... -
