Dokka. Beskrivelse til kvartærgeologisk kart 1816 IV - M 1:50 000 (med fargetrykt kart).
(NGU; Skrifter (383; 41), Journal article, 1983)The superficial deposits and their morphological features within the map-sheet Dokka, 1816 IV, in central south-eastern Norway are classified and described. Ice movements and the course of deglaciation are reconstucted. ... -
Early Proterozoic shallow-marine albite-rich sandstone in the Karasjok Greenstone Belt, Norway.
(NGU Bulletin (403), Journal article, 1985)A remarkably little-deformed sandstone in a roadcut near Karasjok showssedimentary structures characteristic of a subaerially exposed tidalenvironment. The fining upward sequence displays flaser bedding, parallellamination, ... -
Eemian and Weichselian deposits at Bø on Karmøy, SW Norway: a preliminary report.
(NGU (380), Journal article, 1983)Lithological and biostratigraphical studies, including studies of pollen, foraminifera and molluscs, together with amino acid analysis, radiocarbon datings and Uranium-Thorium datings of the deposits in a 21 m section with ... -
Etage 5 i Asker ved Kristiania. Studier over den norske Mellemsilur
(NGU (34), Journal article, 1901)Forkortet: The present work gives the results of the author's researches in the Middle Silurian (Stage 5) in Asker, which lies nearly 10 miles SW from Oslo, on the west side of the head of the Oslofjord. In the first place ... -
Foraminifera in late quaternary deposits from the Oslofjord area.
(NGU (225), Journal article, 1964)Approximately 2500 core samples from 130 borings, 4 m to 40 m deep, in Late Quaternary (latest Allerød through Sub-Atlantic) clay deposits in the Oslofjord area in southeastern Norway were investigated micropaleontologically. ... -
Four sediment cores from the Continental Shelf outside Trøndelag.
(NGU (304), Journal article, 1974)Grain size analysis and clay mineral investigations have been carried out. The cores consist of an assemblage of sand, silt and clay, where the clay content is gradually decreasing from the bottom towards the top of the ... -
Geological investigation of a lower tertiary/quaternary core, offshore Trøndelag, Norway.
(NGU (316), Journal article, 1975)Seismic profiling carried out offshore Trøndelag, Norway, has provided a basis for selecting localities for core sampling of the bedrock. A continous, metre-long core revealing new information was recorded. Sedimentological, ... -
Gravel fraction on the Spitsbergen Bank, NW Barents Shelf.
(NGU (316), Journal article, 1975)The gravel fraction of the bottom sediment on the Spitsbergen Bank, located south of Svalbard in the NW Barents Sea, is composed predominantly of clastic sedimentary rocks, especially sandstone and shale. Betwwen sampling ... -
Heavy-mineral provinces in southern Skagerrak and northern Kattegat
(NGU Bulletin (430), Journal article, 1996)Detailed heavy-mineral studies of the bottom sediment in the Skagerrak-Kattegat area have not been previously reorted. The heavy-mineral suite in the very- fine-sand fraction (63-125um) is dominated (70-91%) by amphibole, ... -
Innerelv member: late Precambrian marine shelf deposit, East Finnmark.
(NGU (288), Journal article, 1973)The Innerelv Member forms part of the succession between the late Precambrian tillites and the Lower Cambrian rocks in eastern Finnmark and it has a considerable lateral extent. It is about 300 m thick in the Tanafjord ... -
Late Precambrian and Cambro-Ordovician sedimentation in East Finnmark.
(NGU (269), Journal article, 1971)The presence of two closely spaced tillite formations within the Precambrian and Cambro-Ordovician sediments of eastern Finnmark permits subdivision into pre-glacial and post-glacial regimes. On the northern side of ... -
Late Quaternary geological development of the Jutland Bank and the initiation of the Jutland Current, NE North Sea
(NGU Bulletin (430), Journal article, 1996)Using shallow seismic and core data, a reconstruction has been made of the Late Pleistocene-Early Holocene palaeogeography of Jutland Bank, NE North Sea. A division of Late Pleistocene and Holocene deposits into five ... -
Lithostratigraphy of the Late Precambrian Løkvikfjell Group on Varanger Peninsula, East Finnmark, North Norway.
(NGU (343), Journal article, 1978)The basal contact of the Løkvikfjell Formation of the former Raggo Group on Varanger Peninsula is an unconformity rather than a thrust as had been previously supposed. A new stratigraphy is formally proposed for this ... -
Mesozoic sediments and structures onshore Norway and in the coastal zone
(NGU Bulletin (450), Journal article, 2010)In mainland Norway, Mesozoic sedimentary rocks (Jurassic and Cretaceous) outcrop only on Andøya. These are the youngest rocks on land anywhere in Norway. Triassic dykes occur in West Norway, while Mesozoic structures and ... -
Origin of shallow gas in Skagerrak and Kattegat - evidence from stable isotopic analyses and radiocarbon dating
(NGU Bulletin (430), Journal article, 1996)In the Danish coastal waters of northern Kattegat - southern Skagerrak, methane occurs both within sediments and as numerous gas seeps. -
Pleistocene and recent sediments of the Norwegian Continental Shelf (62°N-71°N), and the Norwegian Channel area.
(NGU (316), Journal article, 1975)The surface sediments covering the area under consideration can be divided into 4 groups: 1. Till, mainly composed of material derived from the adjacent mainland. 2. Till, mainly containing material derived from Mesozoic-Tertiary ... -
Recent sediment accumulation in the Norwegian Channel, North Sea
(NGU Bulletin (430), Journal article, 1996)In the Norwegian Channel 35 box cores were taken for sedimentological analysis, and 210Po a- and137Cs y-spectroscopy to determine sedimentation rates. Grain sizes were determined and X-ray photographs of the cores were ... -
Recent sedimentation rates across the Norwegian Trough
(NGU Bulletin (430), Journal article, 1996)From the systematic sampling of 20 stations of the Norwegian part of the Skagerrak in 1993, six cores were chosen for determination of recent sedimentation rates by the lead-210 method and verifications by Cs-137 depth ... -
