The Husfjord plutonic complex, Sørøy, northern Norway.
(NGU (378), Journal article, 1983)The Husfjord area of Sørøy is underlain by a plutonic complex which has been emplaced into Vendian to Cambrian metasediments during the Finnmarkian phase of the Caledonian orogeny. The metasedemimentary envelope of the ... -
The hydrochemistry of crystalline bedrock groundwater in Norway
(NGU Bulletin (439), Journal article, 2002)1604 groundwater samples collected from Precambrian and Palaeozoic crystalline bbedrock aquifers and 72 groundwater samples from Quaternary aquifers were analysed for radon, pH, and major and minor elements. A representative ... -
The hydrogeochemistry of Norwegian bedrock groundwater - selected parameters (pH,F,Rn,U,Th,B,Na,Ca) in samples from Vestfold and Hordaland, Norway
(NGU Bulletin (432), Journal article, 1997)Over 300 samples of bedrock groundwater from Hordaland county and the Oslo rift lithologies of Vestfold county have been collected and analysed for radon and fluoride. A selection of 150 samples have been analysed for a ... -
The Iddefjord granite: geology and age
(NGU Bulletin (417), Journal article, 1990)The Iddefjord granite forms part of the Swedish Bohus batholith and ranges in composition from diorite to granite. The granite consists of 13 individual plutons, and the mechanism of intrusion is related to block subsidence ... -

The importance of hydraulic gradient, lineament trend, proximity to lineaments and surface drainage pattern for yield of groundwater wells on Askøy, West Norway.
(NGU Bulletin (439), Journal article, 2002)Groundwater and lineament studies were made on Askøy, an island northwest of Bergen. In addition to field measurements of lineaments and associated fractures, a total of 2695 photolineaments and 409 topolineament were ... -
The irregular base Cretaceous reflector offshore Mid Norway: a possible result for the Mjølnir impact in the Barents Sea
(NGU Bulletin (443), Journal article, 2005)Since the time of the early seismic investigations offshore Mid Norway around 1970, a very characteristic bedrock reflector with a densely small-faulted appearance has been noted, mapped and eventually assigned a base ... -
The Kongsberg Series margin and its major bend in the Flesberg area, Numedal, Buskerud.
(NGU (351), Journal article, 1979)This major boundary is shown to be defined not by the traditional \"Friction Breccia\", but by a much earlier and more extensive mylonite zone. The mylonitisation was produced by a complex westward upthrust of the Kongsberg ... -
The Late Weichselian - Early Holocene Lindhov clay sequence in the Varberg area, southwestern Sweden
(NGU Bulletin (430), Journal article, 1996)A clay sequence with spacific depositional characteristics has been found, both on land and in the sea, in the area surrounding the town of Varberg and extending north along the coast. The clay sequence, here provisionally ... -
The layered gabbro series at Seiland, Northern Norway.
(NGU (184), Journal article, 1953)De geologiske undersøkelser av Seiland ble påbegynt for å klarlegge om de delvis meget mektige grovkornete ganger av albit og nefelin, med mindre mengder av biotitt og magnetitt, kunne utnyttes økonomisk som råstoff i ... -
The lead and zinc bearing veins at Tråk in Southern Norway.
(NGU (250 B), Journal article, 1967)The nearly vertical zinc and lead bearing veins that cut through Precambrian rocks near the Oslo region at Tråk in Bamle Southern Norway, are described. They can be followed for nearly 2.5 km. A younger introuded diabase ... -
The low-grade rocks of the Skålvær area, S. Helgeland, and their relationship to high-grade rocks of the Helgeland Nappe Complex.
(NGU (322), Journal article, 1975)The geological setting of low-grade rocks of the Helgeland Nappe Complex are discussed and it is concluded that the low-grade rocks are part of the nappe complex. Correlation with similar low-grade sequences in (1) the ... -
The manganese vein of Mount Brandnuten, Botnedal, South Norway.
(NGU (213), Journal article, 1961)The manganese deposit on the NE. slope of Mt. Brandnuten near the head-waters of Botnedalen in western Telemark has the shape of a massive vein of vertical attitude. It is conformably intercalated between arkoses of the ... -
The Mesozoic rocks of Andøy, northern Norway.
(NGU (316), Journal article, 1975)The Jurassic-Lower Cretaceous sediments of Andøy are found in a small, downfaulted area on the north-east coast of the island. The Mezosoic sequence is more than 650 m thick, and rests non-conformably on weathered basement ... -
The minerals of the granite pegmatite at Spro, Nesodden, near Oslo a preliminary note.
(NGU (234), Journal article, 1965)A Precambrian granite pegmatit formerly mined for feldspar is situated at Spro, Nesodden, 20 km SSW of Oslo, Norway. It is shown to consist of two different phases. The paragenesis seems to be as follows: 1) Older phase, ... -
The Moyale graphite deposit, Southern Ethiopia
(NGU Bulletin (436), Journal article, 2000)Precambrian metamorphic rocks of southern Ethiopia, belonging to the Pan-African (Mozambique Belt), host the Moyale graphite deposit. The principal rock units are amphibole schists, quartz-feldspar-mica schists, granodiorites, ... -
