New Arctic aeromagnetic data from Spitsbergen, Svalbard Archipelago, have been interpreted. The depths to the top of the magnetic source rocks have been interpreted using profile data, and the interpretation shows that the magnetic basement is deeper than 3 km below sea level over large areas. A picture of basement horsts and grabens emerges from this map. A deep N-S trending trough, more than 8 km deep, exists beneath Isfjorden.

I 2002 publiserte NGU et geologisk kart over Nord-Europa i målestokk 1:4 millioner. Dette heftet beskriver nærmere de geologiske forholdene geologien i de 24 landene og tre sjøområder som omfattes av kartet.
Rapporten omhandler Arco Norway Minerals A/S's Bamble-prosjekt fra årene 1983-85, de enkelte bergartstypene og deres opprinnelse. Spesiell vekt er lagt på de ekshalitive bergarter og tilknyttet mineralisering, bl.a. gull. Forslag til videre prospektering finnes i eget kapittel. Som vedlegg finnes en kartsammenstilling i M 1:100 000. Den bygger på nedfotograferinger av sammenstillinger i M 1:50 000, basert hovedsaklig på publiserte data.
Forkortet: The Varanger Peninsula is underlain by weakly metamorphosed sedimentary rocks of Late Proterozoic to Early Cambrian age. The rocks occur in two regions: the Tanafjorden-Varangerfjorden Region (TVR) (southwestern half of the penin- sula) and the Barents Sea Region (BSR) (northeastern half), juxtaposed along a complex NW-SE-trending fault zone, The Trollfjorden-Komagelva Fault Zone (TKFZ).

In the investigated area three formations can be distinguished: a. charnokitic rocks, which can be subdivided into mainly massive and mainly branded charnokitic migmatites b. garnetiferous migmatites c. glacial deposits Ore-bearing rocks are found only in garnetiferous migmatites.

The Kordalsnuten-Grøneviksåsen prospect is a 2.8 km2 target area with the potential to become a major international hard rock deposit. Located to the north-east of the operating Berakvam quarry owned by Norsk Stein AS, the prospect has been investigated by NGU to assess its significance. In the target area, NGU has identified and analysed two rocks of interest for aggregate production. The dominant rock is a uniform granodiorite which covers nearly ninety percent of the prospect.

Several potential graphite occurrences in Vesterålen were selected for follow-up work based on helicopter-borne geophysical data. The purpose for this is to confirm the existence of the graphite and next to briefly evaluate the quality and quantity of the graphite-bearing structures. The goal for the project, which is sponsored by Nordland county administration, is to increase the knowledge of each individual graphite occurrence.

Mannen is an unstable rock slope in the Romsdal Valley in the Møre og Romsdal County (western Norway). The slope is under continuous monitoring since 2009 by the Åknes/Tafjord Beredskap IKS. As part of the detailed site investigations, two more than 130 m deep, vertical cored boreholes have been drilled in 2010 and 2011.

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 Skagerrak Project is the first major task of the MGK-programme (MGK is the Norwegian acronomy for Marine geological mapping of Norwegian sea-floor areas) which is a joint effort of six governmental institutions involved in various aspects of marine work.
Forkortet: The western coast of Norway is particularly vulnerable to active rockslide development due to the recent post-glacial uplift and the deep incision of the fjords created by glacial activity, leading to extremely steep fjord sides. The purpose of this work was to determine the influence of structural geology on the hazard analysis related to large rock avalanches in the Storfjorden area.
The borehole KH-08-12 was drilled in August/September 2012 by Geo Drilling and the logging was executed in March 2013 by the Geological Survey of Norway (NGU). The borehole is located at WGS-84 6895850N 395400E zone 32W and ca. 735 meters above sea level, at the upper western part of the Åknes rock slope. The drill cores are logged with regards to bedrock type, fracture frequency and zones of interest with respect to sliding plane(s).
Landsat-5 Thematic Mapper (TM) data has been used to map linear structures of three areas of Trøndelag, central Norway, where offshore activities demand more information about geological structures. The aim of the project was to utilise digital TM-data through an image processing system to enhance detection and analysis of large-scale planar structural features in the bedrock of these areas.
This drill hole is the first at Jettan in the Nordnes mountain, named NN-01-12. The borehole was drilled during summer/autumn 2012 by Arctic drilling and the drill core was logged at the Geological Survey of Norway (NGU) in May 2013. The cores are now stored at Løkken drill core and rock sample storage at the NGU. The drill core is approximately 200 metre long (198.8 m) and due to fracture and/or fault zones the drill hole was cemented and re-drilled several times to keep stable.
This report provides guidance for systematisation of geological data from the individual deposits to be stores in the Ore Data Base. This is built on NGUs former data base (FORIBA) (i.e.ore deposits registered in the Mineral Deposit Archive at NGU) which contained deposit numbers given by Foslie and Paulsen. The instruction is derived from the screen pictures to the database, and describes all fields which can be filled out. Options are given for most of the fields.
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.
Rapportene gir en oversikt over forfatterens tidligere arbeider i Grongfeltet. Den følger opp med undersøkelse av 360 prøver fra 1975. Det er tatt bekkesedi- ment- jordprøve- og moseprøver. En del Mo-anomalier påvises. Malmpotensialet diskuteres for Mo og kobber. Resultatene gis i form av kart og tabeller.
Lineament patterns in the coast-region from Lofoten to Loppa, is investigated. Exposure of fault-rocks show a variety of modes of deformation from ductile to brittle.Relative movements are indicated in some places, showing small strike-slip components and large vertical components. The area represents an elevated substratum for post-Caledonian basin-sediments.
Anortosittprovinsen i Rogaland er, som navnet antyder, kjent for sine store forekomster av bergarten anortositt. Området er lite overdekket med løsmasser, slik at berggrunnen er synlig over nesten hele provinsen.
