The geological evolution of the North Sea area in the tectonic framework of North Western Europe.
(NGU (316), Journal article, 1975)The development history of the North Sea area can be subdivided into five stages: 1) Caledonian geosynclinal stage (Cambrian-Silurian), 2) Variscan geosynclinal stage (Devoanin-Carboniferous), 3) Permo-Triassic intracratonic ... -
The geological history of the Grønsennknipa Nappe, Valdres.
(NGU (281), Journal article, 1972)Eocambrian conglomerates and arkoses were deposited on the Precambrian Jotun rocks. The subsequent polyphase structural evolution of this sequence to form the Grønsennknipa Nappe is described. The emplacement of this nappe ... -
The geological interpretation of the Slidre positive gravity anomaly.
(NGU (228), Journal article, 1964)A positive gravity anomaly that occurs in Slidre has an amplitude of 53 mgal and can be separated into two parts. The top of the disturbing body causing the anomaly cannot be deeper than 4 km. Gabbros and mafic gneisses ... -
The geology and petrology of the Rognsund intrusion, West Finnmark, Northern Norway.
(NGU (371), Journal article, 1982)The Rognsund intrusion is an early-Caledonian gabbroic body containing an 800 m thick sequence of metamorphosed cumulates. Well-developed rythmic layering is interpreted in terms of both in situ crystallization and deposition ... -
