NGU har i samarbeid med NVE utført resistivitets- og georadar-målinger ved Elvål. Til sammen er det gjort 5 km georadar fordelt på 7 profiler og 1,7 km resistivitet fordelt på 3 profiler. Målet med undersøkelsene var å karakterisere løsmassetype og finne dyp til fjell. Georadar ble brukt siden metoden egner seg godt til å kartlegge avsetningsstrukturer, grunnvannstand og dyp til fjell. Resistivitet utnytter de elektriske egenskapene til løsmassene.
NGU conducted an airborne geophysical survey in Hemnes and Hattfjelldal municipalities, as part of NGU’s general airborne mapping program. The data acquisition in the Okstindan area was started and completed in August 2021. This report describes and documents the acquisition, processing and visualization of the acquired datasets and presents them in maps.
NGU conducted an airborne geophysical survey in Stjørdal, Selbu, Malvik and Meråker municipalities, as part of NGU’s general airborne mapping program. This report describes and documents the acquisition, processing and visualization of the acquired datasets and presents them in maps. The geophysical surveys consist of 2655 line-km data, covering an area of 535 km2 flown on July 21st to 29th 2021 and August 30th to September 6th 2021. The NGU modified Geotech Ltd.
Del av forsiden av årsmeldingen.
En detalj er en del av et hele. I årsmeldingen «I detalj», forteller vi om små og store enkeltheter ved Norges geologiske undersøkelse (NGU) i 2021.
NGU kartlegger Norges geologi og sprer kunnskap om den. I SMART, årsmeldingen for 2020, viser vi noe av det vi har oppnådd det siste året. God lesing!
Denne rapporten gir en oversikt over in-situ verdien av statens mineraler i Norge. Statens mineraler er metallene med egenvekt 5 g/cm3 eller høyere pluss svovel, titan og arsen. I tillegg er scandium og beryllium inkludert. For noen forekomster er fosfor en viktig bi-komponent og er derfor inkludert der vi har tilgjengelig informasjon. In-situ verdi er definert som verdien i bakken, det vil si verdien før alle produksjonskostnader er trukket fra.
NGU conducted an airborne geophysical survey in Øksfjord area, in Kvænangen, Loppa og Alta municipalities in Troms and Finnmark, as part of NGU’s general airborne mapping program. The data acquisition in the Øksfjord area was carried out from 20th to 31st of August 2019.
This report describes and documents the acquisition, processing and visualization of the acquired datasets and presents them in maps. The geophysical survey consists of 8500 line-km data, covering an area of 1700 km2, with 4600 km (920 km2) flown in June from Stiklestad, Verdal, and 3900 km (780 km2) flown in August from the base in Gaulstad in Ogndalen.

In the frame of the GREENPEG project NGU and terratec Geophysical Services have compiled a petrophysical database of European pegmatite ores and wall rocks from so far four different sites with different types of pegmatites in different settings. With the aim to develop toolsets for hidden pegmatite exploration, the GREENPEG project wants to overcome the lack of exploration technologies for pegmatite ore deposits.
NGU conducted an airborne geophysical survey in Byglandsfjorden area, in Bygland, Åseral og Åmli municipalities in Agder County, as part of NGU’s general airborne mapping program. The data acquisition in Byglandsfjorden area was carried out May 20th to June 19th, 2021. This report describes and documents the acquisition, processing and visualization of the acquired datasets and presents them in maps.
Stiksmoen is located on a west-facing slope at approximately 120 m a.s.l. in the southern end of Aurlandfjord (Flåm municipality, Vestland county). The unstable rock slope is bounded by a well-developed backscarp, wide open in the north and open but less developed in the southern sector. The lower limit is mapped close to the foot of the frontal cliff of the unstable rock mass.
Sammendrag: Norges geologiske undersøkelse (NGU) utarbeider i samarbeid med Kartverket og Havforskningsinstituttet (HI) marine grunnkart over utvalgte sjøområder i kommunene Skjervøy og Kvænangen i pilotprosjektet Marine grunnkart i kystsonen. Deler av Nordreisa kommune er også inkludert i kartleggingen. Under feltarbeid med F/F Seisma i august 2021 hentet NGU opp ti korte sedimentkjerneprøver fra sjøbunnen på utvalgte lokaliteter.
NGU conducted an airborne geophysical survey in the Selbu, Tydal and Haltdalen area from May to October 2019. This report describes and documents the acquisition, processing, and visualization of the recorded datasets, presented in maps including Røros area data. The geophysical survey results consist of approximately 13000 line-km, covering an area of 2600 km2.
Denne rapporten oppsummerer og tolker de sedimentologiske data som ble samlet inn hhv. 16/10 og 4/11 2019, samt 13/1 og 18/5 2020 i forbindelse med NIKUs arkeologiske utgraving i Kjøpmannsgata 36-38. De beskrevne sedimenter under kulturlagene var blottet i to profiler og to seksjoner der sistnevnte ble logget. Det ble samlet inn enkelte prøver.Sedimentene er lagdelte og domineres av sand og grus som er relativ dårlig sortert og nesten strukturløse.
This report is part of the SPARDIG project. The main aim of the project has been to transform old analogue sparker records from the Nonvegian continental shelf into SEG-Y format.
Forside rapport om geologiske ressurser i Trøndelag
Trøndelags geologi gir uante grønne muligheter. Du leser sannsynligvis dette på en mobiltelefon, en bærbar PC eller et nettbrett. Visste du at skjermene, batteriene og teknologien på disse digitale flatene krever metaller og mineraler som i dag klassifiseres som kritiske for det grønne skiftet? Videre lurer du kanskje på hva det har å gjøre med geologien i Trøndelag? Geologi utgjør det fysiske grunnlaget vi står, går, bygger og bor på.
