The project is aimed to achieve a better understanding of shallow geological/seabed conditions and processes to support technical and environmental aspects of exploration and production along the western margin of the Hammerfest Basin and Loppa High, and in the Tromsø Basin/lngøydjupet area.
A geological excursion guide with thematic articles prepared for the NATO. Advanced Study Institute Meeting held at Moi, Norway, 1984.
The Hamn gabbro on Senja is an arcuate body extending from Hamn in the N to Gryllefjordbotn in the S, a distance of just under 10 km. Its average width is ca. 2 km. Its age is 1800±3 Ma, based on U-Pb dating of zircon. The Ni mineralization at the shore at Hamn was mined from 1872-1886, yielding 105,000 t of ore: c. 1000t of nickel and cobalt and 500 t of copper were produced from ore with an average grade of 0.9%Ni. The main ore lens at Hamn is c.
This report gives an overview of the geology, the history of investigations and all previous data (now in digital form) on the distribution of P2O5 and apatite in the Lillebukt Alkaline Complex (LAC) and some selected adjacent areas.
This report gives an overview of the geology, the history of investigations and all previous data (now in digital form) on the distribution of P2O5 and apatite in the Lillebukt Alkaline Complex (LAC) and some selected adjacent areas. The LAC is situated on the southern central part of the island Stjernøy in the Altafjord 45 km NW of Alta.
The Mjølnir impact crater was discovered in seismic reflection data in the 1990's and the detailed structure is well established. The submarine crater, situated in the southwestern Barents Sea, is believed to have a crater diameter of about 40 km, and a shallow relief (About 50 m). The crater is buried under a layer of sediments. Stratigraphic relationships (drill core 7329/03-U01) indicate a Cretaceous formation age around 140 Ma.
The aim of this study is to improve the quality of laser ablation inductively coupled mass spectrometry (LA-ICP-MS). Over the last decade the Geological Survey of Norway has routinely performed trace element analyses of quartz from both operating and potential quartz deposits by LA-ICP-MS. The determined phosphorus concentrations are, with but few exeptions, consistently within the range of 10 to 30 µgg-1; results which seem to be too high and too consistent.
The Geological Survey of Norway has compiled an inventory of hard rock aggregate deposits in coastal Norway. This report contains a catalogue of Norwegian coastal quarries presently in production and exporting, as well as of potential production areas along the coast of South-Central Norway and Finnmark. In 2008 17.2 million tonnes of aggregates were exported to Europe, and about 2.7 million tonnes were used by the offshore oil and gas industry on the continental shelf.
Background: The Misvær massif, with a surface extension of ca. 8 km2, is situated near the sea, abount 130 km from Glomfjord by boat. Its apatite potential was recognized in 2007 by Norland Mineral, an orgnaisation established and financed by the county administration in Nordland and collaborating with the Geological Survey of Norway (NGU).
Thermal response tests (TRT) are widely used to measure the effective thermal conductivity and borehole resistance in a well. The gained data serve as the basis for the dimensioning of larger ground-source heat-pump installations with closed loop systems. The influence of groundwater flow on a TRT in fractured aquifers is not well understood. An attempt to quantify the influence of groundwater was done by pumping of groundwater from a nearby well during the TRT.
A high sensitivity aeromagnetic survey, BASAR-08, was carried out in an area of 80,600 km2 in the Norwegian Barents Sea. Data processing comprised spike-removal and data editing, systematic corrections, statistical, and micro-levelling. Processing and interpretation of the new dataset included a reprocessing of the BAS-06 survey, covering the eastern Norwegian Barents Sea and the entire undisputed part fo the Nordkapp Basin. Several potential field maps were produced from the survey area.
Chemical analyses of main, minor and trace elements have been made of Ordovician black (alum-) shale samples collected at two different localities and one waste pile in the greater Oslo area. The study is aimed at identification of differences between black shales from different localities by using main and trace element concentrations in whole rock for "fingerprinting".
Past landslide deposits store valuable and important information that can be used for geohazard analysis. This includes data on frequency of events, run-out distances and dynamics of rock avalanches. Investigations of rock-avalanche events also give possibilities for back-calculation (modelling of avalanches), such as conditions for sliding in potential unstable slopes. A complete swath bathymetry dataset from the inner parts of Storfjorden and its tributary fjords has been studied.
