Fortrolig til 04.05.2003. The Engebøfjellet eclogite deposit is situated at the northern side of Førde- fjord near the small community Vevring in Naustdal kommune, Sogn og Fjordane county, W.Norway. Geologically the Førdefjord area belongs to the "Western Gneiss Region", between the Devonian Kvamshesten basin to the south and the Devonian Håsteinen basin to the North.
In the first part of the report, a synopsis is presented of the general geology and tectonostratigraphy of this part of Central Norway, with a slightly more detailed account given of the geology of Fosen Peninsula. The second part comprises an excursion guide, spanning 3 days, covering the southern district of Fosen from Rørvik to Ørland and to the outer coast near Sandnes; and then continuing along the Verran Fault (Møre-Trøndelag Fault Complex) via Verrabotn and Beitstadfjorden to Steinkjer.
The Geological Survey of Norway is in the process of making an inventory of hard-rock aggregate deposits in coastal Norway. This report contains a cata- logue of Norwegian coastal quarries at present in production and of potential resources along the coast of southern Norway. 8.2 million tons og aggregates were exported to Europe in 1997 and ca. 0.9 million tons was used offshore (continental shelf).
Gravity data have been interpreted with a view to determining the depth extent of the Devonian Hornelen Basin. We find that the Hornelen Basin has a maximum depth of 3-4 km (below sea level). Uncertainity in the modelling originates in the low density contrast between the Devonian sedimentary rocks and the crystalline basement rocks. There is a rather close correlation between surface geology and gravity maps, which provides constraints on the gravity modelling.
Isotope geochronologic data analysis is an integral aspect of nearly every type of tectonic study. However, no regional compilation of Norwegian geo- chronologic data has been assembled since 1986 (Kullerud and co-workers for the Western Gneiss Region), despite the plethora of new, high-precision geochronologic data produced in the intervening 11 years.
During June, 1997, a helicopter geophysical survey was carried out over part of Nordmarka, an area immediately northwest from Oslo. The purpose of the survey was to provide geophysical information to improve geological mapping in the area. Approximately 3260 line-kilometers of VLF, radiometric, magnetometric, and electromagnetic data were acquired, covering an area of approximately 650 sq km, mostly over the area covered by NGUs Oppkuven mapsheet.
This report presents preliminary results of detailed geological follow-up studies and diamond drilling carried out in the Okstindan Area, Nordland, Norway in the period July to August 1997. Preliminary results from drilling done in November and December 1997 is included in this report. Field work to the south and at the base of the Okstindan massif along the Kongsfjell / Anders Larsa contact revealed no signs of mineralization.
Neotectonic crustal deformations have been reported at a large number of locations in Norway (both on local and regional scales). The NEONOR Project represents a national effort by several national research and mapping institutions to investigate these phenomena through a multidiciplinary approach. Both the industry and the Norwegian Research Council contribute with major financial support. The main objectives of the NEONOR.
Altaskiferen i Peskaområdet er kartlagt, og innenfor den drivverdige sonen er skilt mellom homogen skifer, vesentlig drivverdig og en øvre sone av variabel kvalitet. Grensene mellom disse to er gradvis, og generelt har vi en avtakende kvaalitet oppover innenfor øvre del av skifersonen. Topp og bunn på skifersonen er definert med temmelig stor sikkerhet. Sprekketettheten i skifersonen varierer sterkt, og området er delt inn i soner på grunnlag av sprekketettheten.
This guideline has been produced to assist the management of contaminated sites in Latvia, in particular disused Russian military sites. A risk-based approach is proposed for adoption in the assessment of such sites in line with the approach adopted in recent years by other countries in the European Union.
Denne rapporten presenterer foreløpige resultater av feltarbeid i området øst for Røssvatnet i Nordland, utført i perioden 9 juli - 10 september 1997. Arbeidet gjennomføres som et samarbeid med NGU og Institutt for geologi ved Universitetet i Oslo i forbindelse med førsteforfatterens hovedfagsoppgave.
I samarbeid med Rogalsnd fylke har NGU skaffet til veie geologiske data, utført kartlegging og sammnestilt ewt berggrunnsgeologisk kart i målestokk 1:25 000 over området Sokndal - Mydland - Berrefjord. I tillegg er det gjort innledende betraktninger om mineralressurser. Tilsammen utgjør dette Del 1 av et planlagt 2-årig prosjekt som er rettet mot mineralske ressurser.
