Age and petrogenesis of the Tinn granite, Telemark, South Norway, and its geochemical relationship to metarhyolite of the Rjukan Group.
Andersen, Tom; Andresen, Arild; Sylvester, Arthur G. (NGU Bulletin (440), Journal article, 2002)The Tinn granite is a Mid Proterozoic, foliated pluton, situated in the central part of the Telemark Sector, South Norway. It is spatially associated with metarhyolite belonging to the Tuddal Formation of the Rjukan Group ... -
Basement-cover relations and Caledonian tectonostratigraphy of Sandsøya, Grytøya, Åkerøya and Kjøtta, Western Gneiss Region, North Norway.
van Winkle, Steve W.; Andresen, Arild; Steltenpohl, Mark G. (NGU Bulletin (431), Journal article, 1996)Rocks of Sandsøya, Grytøya, Åkerøya, and Kjøtta, represent four Caledonian Tectonic settings: (1) pre-Caledonian Baltic crystalline basement of the Western Gneiss Region, including intrusively enclosed supracrustal rocks; ... -
Lithostratigraphic correlation of the Salangen (Ofoten) and Balsfjord (Troms) Groups: evidence for the post-Finnmarkian unconfirmity, North Norwegian Caledonides.
Andresen, Arild; Tull, James F.; Steltenpohl, Mark G. (NGU Bulletin (418), Journal article, 1990)Detailed mapping around Ofotfjorden (68-69\u00B0N)demonstrates many tectonostratigraphic and lithostratigraphic similarities with the Caledonian allocthons in the Balsfjord area, 150 km to the north. Lithostratigraphic ... -
New fossil finds from the Cambro-Silurian meta-sediments on Hardangervidda.
Andresen, Arild (NGU (304), Journal article, 1974)The occurrence of Actinoceroid cephalopods (Ormoceras(?) sp.), brachipods (Orthis ss.), and trilobites (Ptychopyge sp.) in a crystalline limestone overlying bluish quartizite on Hardangervidda indicates that Orthoceras ... -
Petrography and structural history of the Caledonian rocks north of Haukelisæter, Hardangervidda.
Andresen, Arild (NGU (314), Journal article, 1974)The main features of the geology of the Caledonian nappe front north of Haukelisæter are described. The Precambrian basement in this area is overlain by an autochthonous\/parautochthonous sequence in the east and by ... -
Structural succession in a part of the outer Hardangerfjord area, West Norway.
Naterstad, Johan; Andresen, Arild; Solli, Arne (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 ... -
Tectonic succession of the Caledonian nappe front in the Haukelisæter- Røldal area, Southwest Norway.
Naterstad, Johan; Jorde, Knut; Andresen, Arild (NGU (292), Journal article, 1973)It is concluded from reconnaissance studies on Hardangervidda that a succession of 5 allochthonous units occurs above the Precambrian basement and its autochthonous\/parautochthonous cover. The units are named from bottom ... -
Timing of late- to post-tectonic Sveconorwegian granitic magmatism in South Norway.
Andersen, Tom; Sylvester, Arthur G.; Andresen, Arild (NGU Bulletin (440), Journal article, 2002)Dating of late- to post-tectonic Sveconorwegian granitic intrusions from South Norway by the SIMS U-Pb method on zircons and by internal Pb-Pb isochrons on rock-forming minerals indicates a major event of granitic magmatism ...
