Gabrielsen, Roy Helge; Gianennas, Pangiptis, A.; Sokuotis, Dimitrios; Willingshofer, Ernst; Hassaan, Muhammed; Faleide, Jan Inge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The Barents Shear Margin separates the Svalbard and Barents Sea from the North Atlantic. During the break-up of the North Atlantic the plate tectonic configuration was characterized by sequential dextral shear, extension, ...

Hassaan, Muhammad; Faleide, Jan Inge; Gabrielsen, Roy Helge; Tsikalas, Filippos (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)An extensive, reprocessed two-dimensional (2D) seismic data set was utilized together with available well data to study the Tiddlybanken Basin in the southeastern Norwegian Barents Sea, which is revealed to be an excellent ...

Kornprobst, Jacques; Abalos, Benito; Barbey, Pierre; Boullier, Anne-Marie; Burg, Jean-Pierre; Capdevila, Ramon; Claesson, Stefan; Cordani, Umberto; Corrigan, David; Gabrielsen, Roy Helge; Gil-Ibarguchi, Jose I.; Johansson, Åke; Letsch, Dominik; Le Vigouroux, Philippe; Upton, Brian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)This work is a review of Boris Choubert’s paper (1935), which was published in French under the rather devalorizing title: “Research on the Genesis of Palaeozoic and Precambrian Belts.” Despite its innovative content, this ...

Gabrielsen, Roy Helge; Skurtveit, Elin; Faleide, Jan Inge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The Draupne Formation is the most important source and cap rock for North Sea hydrocarbon plays. It also provides the primary seal for potential CO2 storage on the Norwegian Continental Shelf, but it has been a concern ...

Hassaan, Muhammad; Faleide, Jan Inge; Gabrielsen, Roy Helge; Tsikalas, Filippos (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)High quality reprocessed seismic reflection profiles and available wells were used to study the little studied southeastern Norwegian Barents Sea and east Finnmark Platform. The study area comprises prominent structural ...
-
Indrevær, Kjetil; Gac, Sebastien; Gabrielsen, Roy Helge; Faleide, Jan Inge (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)The Loppa High area has been subject to several events of uplift and subsidence from the Late Paleozoic to Present. The driving mechanisms behind the vertical movements, however, are not fully understood. We propose that ...

Gabrielsen, Roy Helge; Roberts, David; Gjelsvik, Tone; Sygnabere, Trond Olav; Hassan, Muhammad; Faleide, Jan Inge (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)On Varanger Peninsula, the roughly NW–SE-trending Trollfjorden–Komagelva Fault Zone separates Neoproterozoic successions that accumulated in a shallow-marine platformal domain to the SW of the fault from deepmarine basinal ...
-
Indrevær, Kjetil; Gabrielsen, Roy Helge; Faleide, Jan Inge (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Tectonic inversion of rift basins is most commonly reported in the literature to occur after rifting has ceased. In contrast, we present evidence for synrift, localized tectonic inversion from the Loppa High area, southwestern ...
-
Hassaan, Muhammad; Faleide, Jan Inge; Gabrielsen, Roy Helge; Tsikalas, Filippos (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Potential field data, reprocessed regional 2D seismic reflection profiles and 3D seismic tied to wells were used to study the late Devonian-Permian development of the Nordkapp Basin in Barents Sea. The composite basin can ...

Gabrielsen, Roy Helge; Zalmstra, Heleen; Sokoutis, Dimitrios; Willingshofer, Ernst; Faleide, Jan Inge; Braut, Hanna Lima (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Fault systems in extensional basins commonly display geometries that vary with depth, reflecting depth- and lithology-dependent mechanical strength. Using an experimental approach, we investigate this relationship by ...
-
Hassaan, Muhammad; Faleide, Jan Inge; Gabrielsen, Roy Helge; Tsikalas, Filippos; Grimstad, Silje (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Reprocessed, regional, 2D seismic reflection profiles, 3D seismic volumes and well data (exploration and shallow boreholes), combined with 2D structural restorations and 1D backstripping were used to study the post-salt ...
-
Kalani, Mohsen; Faleide, Jan Inge; Gabrielsen, Roy Helge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)This study focuses on the tectonic evolution of the greater Egersund Basin in the Norwegian central North Sea, with special emphasis on Late Paleozoic extensional tectonics following Caledonian collapse and the Variscan ...

Torgersen, Espen; Gabrielsen, Roy Helge; Ganerød, Morgan; van der Lelij, Roelant; Schönenberger, Jasmin; Nystuen, Johan Petter; Brask, Sofie (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Brittle reactivation of plastic shear zones is frequently observed in geologically old terranes. To better understand such deformation zones, we have studied the >700 Ma long structural history of the Himdalen–Ørje Deformation ...
-
Lundmark, Anders Mattias; Gabrielsen, Roy Helge; Strand, Tor; Ohm, Sverre Ekrene (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)Intrusive and extrusive mafic igneous rocks in the Embla oil field, central North Sea, testify to repeated post-Caledonian magmatism on the northern flank of the Mid North Sea High. The igneous rocks are highly clay- and ...
