Jan Mayen Ridge Sampling

Edited by Stephane Polteau, Adriano Mazzini, Mikal Trulsvik, and Sverre Planke.

TGS and Volcanic Basin Energy Research (VBER) conducted systematic seabed sampling of a 1000 meter high cliff on the Jan Mayen Ridge in September 2011. More than 200 kg of rocks and sediments were recovered from twelve sampling stations.

The samples give exciting insight into the petroleum geology of the Jan Mayen Ridge. Diverse sedimentary rocks of Mesozoic age (250 to 65 million years) were recovered. Advanced geochemical analyses suggest active seepage of Jurassic oil and a working hydrocarbon system.

Highlights

  • Systematic sampling of a kilometer high escarpment with subcropping sediments
  • Cenozoic and Mesozoic samples recovered
  • Pseudo-well provides stratigraphic tie to seismic data
  • Petroleum seep analysis and age determination
