The Barents project started in 2012 and includes:

  • Airborne full tensor gravity and transient electromagnetic (VTEM).
  • A 74 km long seismic reflection and AMT profile from the Kiruna area.
  • Bedrock mapping in key areas representing specific parts of the supracrustal rocks in northern Norrbotten.
  • Regional mapping in southern Norrbotten.
  • Till geochemistry sampling and analyses.
  • New reports are uploaded at Geolagret, search for "Barents"

Airborne measurements within the Barents project

Helicopter -borne versatile time domain electromagnetic (VTEM) measurements were made in August 2013 by Geotech Airborne Ltd. Full tensor gravity measurements carried out from aircraft over the same area by Bell Geospace. Both measurements were done with 500 m line spacing over an area of 2088 km2.

Seismic  reflection and AMT profile

A 74 km long seismic and AMT profile were made in the Kiruna area.


Location site for the seismic profile

Bedrock mapping

15 key areas have been selected in northern Norrbotten with focus on supracrustal rocks in order to study the stratigraphy, structures, mineralizations, metamorphism and their geophysical propertis. Reports can be found at Geolagret.

Regional mapping 1:250 000 in southern Norrbotten

The aim is to gather modern geological and geophysical information in southern Norrbotten in order to deepen knowledge in an area there is a huge lack of modern information. The results will be compiled in a synthesis together with ongoing mapping projects in 1:50000 in the area.


Till geochemistry

2400 samples collected from Norrbotten County during 2012 and 203. These results are stored in the SGU databases.
