Benthic foraminiferal evidence of environmental change in the Skagerrak over the past six decades
(NGU Bulletin (430), Journal article, 1996)High resolution analyses of fossil benthic forminiferal assemblages have been performed on two short (<40cm) sediment cores from the deep Skagerrak Basin, NE North Sea. 210 Pb-datings of replicate cores from the same two ... -
Distribution of rock fragments, grain size and chemical elements of tills in the Lake Mjøsa area, eastern Norway
(NGU Bulletin (453), Journal article, 2014)The Lake Mjøsa area in eastern Norway forms an interesting case to study glacial erosion, transport and deposition because bedrock lithology (source of till) is relatively well known and the Geological Survey of Norway ... -
Foraminiferfaunaens relasjon til dybdeforholdene i Oslofjorden, med en diskusjon av de senkvartære foraminifersoner.
(NGU (226), Journal article, 1964)I de sen- og postglaciale marine sedimenter i Oslofjordområdet finnes en rik representasjon av benthoniske småforaminiferer. Gjennom studier av disse, foretatt av Feyling-Hanssen (1945 a, b; 1957, 1963 og 1964), er det ... -
Foraminiferfaunaens relasjon til dybdeforholdene i Oslofjorden, med en diskusjon av de senkvartære foraminifersoner.
(NGU (226), Journal article, 1964)Hovedvekten i arbeidet er lagt på et bathygrafisk studium av foraminiferfaunaen i Oslofjorden, ved at det er tatt prøver i en del profiler i forskjellige deler av fjorden - fra grunt til dypt vann. Foraminiferfaunaene i ... -
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 ... -
Marmorforekomster i Midt-Norge: Geologi, isotopgeokjemi og industri- mineralpotensiale
(NGU-Rapport (94.042), Report, 1994)Marmorforekomster opptrer på 3 tektonostratigrafiske nivåer i Midt-Norge: Seve- og K\u00F6li-ekvivalente dekker i Øvre allokton samt Helgeland dekkekompleks i Øverste allokton. Amfibolittfacies Sevedekke-bergarter opptrer ... -
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 ... -
Sea-bed sediments and sediment accumulation rates in the Norwegian part of the Skagerrak
(NGU Bulletin (430), Journal article, 1996)Grain-size analysis show that the sea-bed sediments over large areas in the Norwegian Trench and along its northern slope consist of homogeneous silty clay with a clay content of 50-75% and generally less than 2% sand. ... -
Seabed sedimentary environments and sediments (genesis) in the Nordland VI area off northern Norway
(NGU-Rapport (2017.046), Report, 2017)This report presents maps of sedimentary environments and seabed sediments (genesis) in the Nordland VI management area off northern Norway. The maps, which cover about 25 000 km\u00B2 and water depths from 60 m to 2700 ... -
Sedimentkjerner fra Barentshavet Øst tatt på MAREANO-tokt med G.O. Sars i 2014
(NGU-Rapport (2016.021), Report, 2016)På tokt MAREANO 2014-2016 med forskningsfartøyet G.O. Sars i 2014 ble det tatt sedimentkjerner med gravitasjonsprøvetaker (GC) på åtte stasjoner i Barentshavet Øst. Hensikten var i første rekke å få informasjon om mektighet ... -
Suspension sedimentation of coarse silt and sand in northern Skagerrak: textural and mineralogical trends
(NGU Bulletin (430), Journal article, 1996)The minor coarse-silt and sand fraction of muddy bottom sediments at 74 sites in northern Skagerrak is interpreted to have been mostly transported in suspension, aided by frequent reworking and the buoyancy of large ... -
The conglomerates of the Sel Group, Otta-Vågå area, Central Norway: an example of a terrrane-linking succession
(NGU Bulletin (425), Journal article, 1993)The conglomerates at or near the base of the Sel Group in the Otta-Vågå area have a special significance in the interpretation of the palaeogeographical and geotectonic development of the Scandinavian Caledonides. They ... -
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 ... -
Thickness, distribution and depositional environment of Holocene sediments in the Norwegian part of the Skagerrak
(NGU Bulletin (430), Journal article, 1996)A regional seismic reflector separating an uppermost low-reflectivity Holocene unit from an acoustically layered, Lake Weichselian, glaciomarine unit below has been mapped in the Norwegian Skagerrak between Langesund and ...
