Architecture of growth basins in a tidally influenced, prodelta to delta-front setting: The Triassic succession of Kvalpynten, East Svalbard
Smyrak-Sikora, Aleksandra; Osmundsen, Per Terje; Braathen, Alvar; Ogata, Kei; Anell, Ingrid Margareta; Mulrooney, Mark Joseph; Zuchuat, Valentin (Peer reviewed; Journal article, 2020)World‐class examples of fault‐controlled growth basins with associated syn‐kinematic sedimentary fill are developed in Upper Triassic prodelta to delta‐front deposits exposed at Kvalpynten, SW Edgeøya in East Svalbard. ... -
Architecture, deformation style and petrophysical properties of growth fault systems: the Late Triassic deltaic succession of southern Edgeøya (East Svalbard)
Ogata, Kei; Mulrooney, Mark; Braathen, Alvar; Maher, Harmon; Osmundsen, Per Terje; Anell, Ingrid Margareta; Smyrak-Sikora, Aleksandra; Balsamo, Fabrizio (Peer reviewed; Journal article, 2018-05-07)The Late Triassic outcrops on southern Edgeøya, East Svalbard, allow a multiscale study of syn‐sedimentary listric growth faults located in the prodelta region of a regional prograding system. At least three hierarchical ... -
Deep Crustal Flow Within Postorogenic Metamorphic Core Complexes: Insights From the Southern Western Gneiss Region of Norway
Wiest, Johannes; Osmundsen, Per Terje; Jacobs, Joachim; Fossen, Haakon (Peer reviewed; Journal article, 2019)Viscous crustal flow can exhume once deeply buried rocks in postorogenic metamorphic core complexes (MCCs). While migmatite domes record the flow dynamics of anatectic crust, the mechanics and kinematics of solid‐state ... -
From Caledonian collapse to North Sea Rift: The extended history of a metamorphic core complex
Wiest, Johannes; Wrona, Thilo; Bauck, Marit Stokke; Fossen, Haakon; Gawthorpe, Rob; Osmundsen, Per Terje; Faleide, Jan Inge (Journal article; Peer reviewed, 2020)Extensional systems evolve through different stages due to changes in the rheological state of the lithosphere. It is crucial to distinguish ductile structures formed before and during rifting, as both cases have important ... -
Mesozoic-Cenozoic regional stress field evolution in Svalbard
Maher, Harmon; Senger, Kim; Braathen, Alvar; Mulrooney, Mark Joseph; Smyrak-Sikora, Aleksandra; Osmundsen, Per Terje; Ogata, Kei (Journal article; Peer reviewed, 2020)Cooling fracture orientations in diabase sills associated with the Cretaceous High Arctic Large Igneous Province and syn‐sedimentary Triassic faults help constrain a model for Svalbard's (NE Barents Shelf) Mesozoic stress ... -
Segmentation of the Caledonian orogenic infrastructure and exhumation of the Western Gneiss Region during transtensional collapse
Wiest, Johannes; Jacobs, Joachim; Fossen, Haakon; Ganerød, Morgan; Osmundsen, Per Terje (Journal article; Peer reviewed, 2021)The (ultra)high-pressure Western Gneiss Region of the Norwegian Caledonides represents an archetypical orogenic infrastructure of a continent–continent collision zone. To test established exhumation models, we synthesize ...
