Jakob, Johannes; Andersen, Torgeir Bjørge; Kjøll, Hans Jørgen (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)nterpretations of the pre-Caledonian rifted margin of Baltica commonly reconstruct it as a simple, tapering, wedge-shaped continental margin dissected by half graben, with progressively more rift-related magmas towards the ...

Jakob, Johannes (Doctoral thesis / Doktoravhandling, 2016)In plate tectonics scientists study the present and past motions of the lithospheric plates over the Earth’s surface. The reconstruction of the location and orientation of the continents and oceans in deep time is referred ...

Gaina, Carmen; Jakob, Johannes (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)Many of our planet's “crises” were the result of sudden changes in plate tectonic configuration or catastrophic outbursts of volcanism caused by mantle plume impingement at the base of the lithosphere. At the Paleocene-Eocene ...

Domeier, Mathew; Shephard, Grace; Jakob, Johannes; Gaina, Carmen; Doubrovine, Pavel; Torsvik, Trond Helge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The notorious ~60° bend separating the Hawaiian and Emperor chains marked a prominent change in the motion of the Pacific plate at ~47 Ma (million years ago), but the origin of that change remains an outstanding controversy ...

Jakob, Johannes; Andersen, Torgeir Bjørge; Mohn, Geoffroy; Kjøll, Hans Jørgen; Beyssac, Olivier (Chapter / Bokkapittel / PublishedVersion; Peer reviewed, 2022)The Scandinavian Caledonides formed during the continental collision between Baltica and Laurentia. During the collision, a complex nappe stack was thrust over the Baltican continental margin. The orogen can be subdivided ...

Turino, V.; Magni, Valentina; Kjøll, Hans Jørgen; Jakob, Johannes (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract The transition between non‐rifted continental lithosphere and oceanic lithosphere in rifted margins can display a wide range of characteristics, depending on the regional tectonic evolution. The velocity and ...

Andersen, Torgeir Bjørge; Jakob, Johannes; Kjøll, Hans Jørgen; Tegner, Christian (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract: The Pre-Caledonian margin of Baltica has been outlined as a tapering wedge with increas- ing magmatism towards the ocean–continent transition. It is, however, well known that margins are complex, with different ...
