Slagstad, Trond; Henderson, Lain; Roberts, Nick MW; Kulakov, Evgeniy; Ganerød, Morgan; Kirkland, Christopher L.; Dalslåen, Bjørgunn Heggem; Creaser, Robert A; Coint, Nolwenn (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The tectonic setting and mechanisms and duration of emplacement of Proterozoic massif-type anorthosites and the significance of typically associated ultrahigh-temperature (UHT) host rocks have been debated for decades. ...

Slagstad, Trond; Kulakov, Evgeniy; Kirkland, Christopher L.; Roberts, Nick, M.W.; Ganerød, Morgan (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)The Grenville, Sveconorwegian, and Sunsas orogens are typically inferred to reflect collision between Laurentia, Baltica, and Amazonia at ca. 1.0 Ga, forming a central portion of the Rodinia supercontinent. This triple‐junction ...

Jurassic fast polar shift rejected by a new high-quality paleomagnetic pole from southwest Greenland Kulakov, Evgeniy; Torsvik, Trond Helge; Doubrovine, Pavel V.; Slagstad, Trond; Ganerød, Morgan; Silkoset, Petter; Werner, Stephanie C. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)A selective compilation of paleomagnetic data from North America indicates that a vast amount of rapid polar motion occurred in Late Jurassic time. The over 30° polar shift that accumulated during a relatively short time ...

Austrheim, Håkon Olaf; Engvik, Ane; Ganerød, Morgan; Dunkel, Kristina G; Velo, Mari Roen (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)The Kongsberg and Bamble lithotectonic domains of SE-Norway are known as classical Precambrian high-grade metamorphic terrains. The area has undergone extensive metasomatism with formation of albitites and scapolite-rich ...

Kulakov, Evgeniy; Slagstad, Trond; Ganerød, Morgan; Torsvik, Trond Helge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Here we present new 40Ar/39Ar geochronology, rock magnetic, and paleomagnetic data obtained from rocks from three distinct domains of the Precambrian Sveconorwegian orogen (Southern Norway) that record progressively younger ...

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 ...

Wiest, Johannes; Jacobs, Joachim; Fossen, Haakon; Ganerød, Morgan; Osmundsen, Per Terje (Journal article / Tidsskriftartikkel / PublishedVersion; 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 ...

Owen-Smith, T.M.; Ganerød, Morgan; van Hinsbergen, Douwe J J; Gaina, Carmen; Ashwal, Lewis D.; Torsvik, Trond Helge (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)We provide an independent test for the proposed pre-breakup fits between the South American and African continental margins based on new palaeomagnetic data. In the course of modelling the opening of the South Atlantic ...

Dalslåen, Bjørgunn Heggem; Gasser, Deta; Grenne, Tor; Ganerød, Morgan; Andresen, Arild (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)We present field observations, geochemical data and detrital zircon U–Pb ages from the newly defined Skuggliberga unit of the Oppdal area, central Norwegian Caledonides. The unit occurs in two separate areas, where it ...

Slagstad, Trond; Marker, Mogens; Roberts, Nick M.W.; Saalmann, Kerstin; Kirkland, Christopher L.; Kulakov, Evgeniy; Ganerød, Morgan; Røhr, Torkil Sørlie; Møkkelgjerd, Steinar Halvdan Hansen; Granseth, Anette; Sørensen, Bjørn Eske (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The Sveconorwegian orogeny encompasses magmatic, metamorphic and deformational events between ca. 1140 and 920 Ma at the southwestern margin of Fennoscandia. In recent years, the tectonic setting of this nearly 200 Myr-long ...

Slagstad, Trond; Kulakov, Evgeniy; Anderson, Mark W.; Saalmann, Kerstin; Kirkland, Christopher L.; Henderson, Iain; Ganerød, Morgan (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Late Ediacaran opening of the Iapetus Ocean is typically considered to reflect separation of Baltica and Laurentia during final breakup of the Rodinia supercontinent, with subsequent closure during the Caledonian Orogeny. ...
