Strategies for groundwater prospecting in hard rocks: a probabilistic approach
(NGU Bulletin (439), Journal article, 2002)Private wells in fractured, Precambrian, crystlline rocks are important for rural areas and small communities in Sweden. Since well yields normally are small, systematic approaches to groundwater prospecting are required ... -
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 ... -

Precambrian and Caledonian tectonometamorphic evolution of Northeastern Seiland, Finnmark, North Norway.
(NGU (373), Journal article, 1982)The metamorphic rocks of northeastern Seiland are predominantly Precambrian gneisses and schists. The Fagervik infracrustal complex, composed of tonalitic gneisses, constitutes a basement to the Late Precambrian-Cambrian ... -
Kongsvingerfeltets geologi.
(NGU (246 B), Journal article, 1967)The rocks and tectonic features of the Kongsvinger area are described. The area consists of steeply dipping, probably isoclinally folded supracrustal rocks separated by granites, the latter being cataclastic and schistose. ... -
Metamorphic petrology of the Froland corundum-bearing rocks: the cooling and uplift history of the Bamble Sector, South Norway
(NGU Bulletin (424), Journal article, 1993)Corundum-bearing rocks from Kleggåsen, Froland, preserve metamorphic textures which reflect the cooling and uplift path of the Bamble Sector. The P-T path may be correlated with a T-t path constructed from published ages. ... -
Seismic refraction measurements and continuous seismic profiling on the continental margin off Norway between 60°N and 69°N.
(NGU (316), Journal article, 1975)The sedimentary basin off Norway wedges out near the Norwegian coastline. The ocean side of the sedimentary basin is in contact with oceanic crust along escarpments and the Jan Mayen Fracture Zone. The present study reveals ... -
