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 ... -
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 ... -
Shear zone evolution during core complex exhumation – Implications for continental detachments
Wiest, Johannes; Fossen, Haakon; Jacobs, Joachim (Journal article; Peer reviewed, 2020)The formation of low-angle detachments involves exhumation of previously ductile material and fault zone weakening. To better understand this relationship, we studied a deeply eroded metamorphic core complex, which formed ... -
Tracing the Sveconorwegian orogen into the Caledonides of West Norway: Geochronological and isotopic studies on magmatism and migmatization
Wang, Cheng-Cheng; Wiest, Johannes; Jacobs, Joachim; Bingen, Bernard; Whitehouse, Martin J.; Elburg, Marlina; Sørstrand, Thea Sætren; Mikkelsen, Lise; Hestnes, Åse (Journal article; Peer reviewed, 2021)The Sveconorwegian orogen represents a branch of Grenville-age (~1250–950 Ma) orogenic belts that formed during the construction of the supercontinent Rodinia. This study traces the Sveconorwegian records from its type-area ...
