    • Depositional environments and source rock potential of some Upper Palaeozoic (Devonian) coals on Bjørnøya, Western Barents shelf 

      Janocha, Julian; Wesenlund, Fredrik; Thießen, Olaf; Grundvåg, Sten-Andreas; Koehl, Jean-Baptiste Philippe; Johannessen, Erik P. (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-02-27)
      Upper Palaeozoic strata are potential sources for hydrocarbon plays on the Norwegian Barents Shelf. The island of Bjørnøya (Bear Island) is located on the western margin of the Barents Shelf and represents an exposed part of the Stappen High, which makes it an excellent location to investigate the source rock potential of this succession. Here, we investigate the organic geochemical composition and ...

    • Impact of Timanian thrust systems on the late Neoproterozoic–Phanerozoic tectonic evolution of the Barents Sea and Svalbard 

      Koehl, Jean-Baptiste Philippe; Magee, Craig; Anell, Ingrid (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-12)
      The Svalbard Archipelago consists of three basement terranes that record a complex Neoproterozoic– Phanerozoic tectonic history, including four contractional events (Grenvillian, Caledonian, Ellesmerian, and Eurekan) and two episodes of collapse- to rift-related extension (Devonian–Carboniferous and late Cenozoic). Previous studies suggest that these three terranes likely accreted during the early ...

    • Late Paleozoic-Cenozoic fault correlation and characterization of fault rocks in western Troms, North Norway 

      Koehl, Jean-Baptiste Philippe (Master thesis; Mastergradsoppgave, 2013-05-29)
      The present work focuses on the mapping and description of onshore brittle fault zones on the SW Barents Sea Margin, within gneisses and granitic intrusions belonging to the West Troms Basement Complex. The description of the brittle structures includes the geometry, kinematics and fault rock characteristics, using DEM satellite imaging, structural field work and a microstructural analysis of the ...

    • Mid/Late Devonian-Carboniferous extensional faulting in Finnmark and the SW Barents Sea 

      Koehl, Jean-Baptiste Philippe (Doctoral thesis; Doktorgradsavhandling, 2018-05-24)
      In northern Norway, late/post-Caledonian extension initiated along inverted, brittle-ductile thrusts, e.g. Sørøya-Ingøya shear zone, which truncated existing, margin-oblique, late Neoproterozoic, Timanian faults and margin-parallel, latest Mesoproterozoic-mid Neoproterozoic faults related to the opening of the Asgard Sea and Iapetus Ocean. Inverted thrusts were active through the Devonian and early ...
