Distribution of 30,000 year-old sand deposits in the northern North Sea.
(NGU Bulletin (424), Journal article, 1993)The northern North Sea Plateau represents mainly a coastal sedimentary accumulation towards the north and northeast of thick clay deposits separated by thin sand layers. Regional mapping on this flat plateau has revealed ... -
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, ... -
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. ... -
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 ... -
Temporal variations in the transport of the mine tailings through the Knabenå-Kvina river system, and into the Fedafjord, Norway
(NGU Bulletin (430), Journal article, 1996)Mine tailings from the Knaben Molybdenum Mines were discharged into two lakes in the headwatr area of the Knabeåna-Kvina drainage basin in the period 1918- 1973. A dam was built downstream of the two lakes in 1976 to prevent ...
