Constraining the tectonic evolution of rifted continental margins by U–Pb calcite dating
Hestnes, Åse; Drost, Kerstin; Sømme, Tor Oftedal; Gasser, Deta; Scheiber, Thomas; Linge, Henriette; Chew, David; Jacobs, Joachim (Journal article; Peer reviewed, 2023)We employ U–Pb calcite dating of structurally-controlled fracture fills within crystalline Caledonian basement in western Norway to reveal subtle large-scale tectonic events that affected this rifted continental margin. ... -
Down-dip correlation and modelling of shallow-marine and estuarine deposits in the Sunnyside Member, Book Cliffs, Eastern Utah: implications for the formation of non-depositional discontinuity surfaces
Sømme, Tor Oftedal (Master thesis, 2005-11)The Sunnyside Member is part of the Blackhawk Formation and consists of shallow-marine and estuarine deposits reflecting high-frequency changes in sea level. Detailed mapping of the unit reveals an intra parasequence ... -
Stratigraphic expression of the Paleocene-Eocene Thermal Maximum climate event during long-lived transient uplift—An example from a shallow to deep-marine clastic system in the Norwegian Sea
Sømme, Tor Oftedal; Huwe, Simone Isabelle; Martinsen, Ole Jakob; Sandbakken, Pål Trygve; Skogseid, Jakob; Valore, Lucas (Journal article; Peer reviewed, 2023-02-20)Seismic geomorphology and stratigraphic analysis can reveal how source-to-sink systems dynamically respond to climatic and tectonic forcing. This study uses seismic reflection data from the Norwegian Sea to investigate the ...
