The brittle evolution of Western Norway – A space-time model based on fault mineralizations, K–Ar fault gouge dating and paleostress analysis
Hestnes, Åse; Gasser, Deta; Scheiber, Thomas; Jacobs, Joachim; van der Lelij, Roelant; Schönenberger, Jasmin; Ksienzyk, Anna Katharina (Journal article; Peer reviewed, 2022)Basement fracture and fault patterns on passive continental margins control the onshore landscape and offshore distribution of sediment packages and fluid pathways. In this study, we decipher the spatial-temporal evolution ... -
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. ... -
The post-Caledonian tectono-thermal evolution of Western Norway
Hestnes, Åse (Doctoral thesis, 2023-06-19)En riftet kontinentalmargin viser ofte et karakteristisk landskap som domineres av høye og flate fjell som er separert fra en lavtliggende kyststripe av en tydelig skrent. Mye av vår nåværende forståelse av disse områdene ... -
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 ...
