40Ar/39Ar constraints on the tectonic evolution of the central part of the Mesoproterozoic Sveconorwegian orogen
Scheiber, Thomas; Viola, Giulio; Ganerød, Morgan; Bingen, Bernard (Peer reviewed; Journal article, 2022)Structural data combined with 40Ar/39Ar geochronology of hornblende, muscovite, biotite and plagioclase from 37 localities along three transects allow the time-constrained reconstruction of the Sveconorwegian deformation ... -
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 (Peer reviewed; Journal article, 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 (Peer reviewed; Journal article, 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. ... -
Deconvoluting complex structural histories archived in brittle fault zones
Viola, Giulio; Scheiber, Thomas; Fredin, Ola; Zwingmann, Horst; Margreth, A.; Knies, Jochen (Journal article; Peer reviewed, 2016)Brittle deformation can saturate the Earth’s crust with faults and fractures in an apparently chaotic fashion. The details of brittle deformational histories and implications on, for example, seismotectonics and landscape, ... -
Glacier thinning, recession and advance, and the associated evolution of a glacial lake between 1966 and 2021 at Austerdalsbreen, western Norway
Seier, Gernot; Abermann, Jakob; Andreassen, Liss Marie; Carrivick, Jonathan L.; Kielland, Pål Hage; Löffler, Karina; Nesje, Atle; Robson, Benjamin Aubrey; Røthe, Torgeir Opeland; Scheiber, Thomas; Winkler, Stefan; Yde, Jacob Clement (Peer reviewed; Journal article, 2023)The Jostedalsbreen is the largest ice cap in Norway and mainland Europe. Rapid retreat of many of its outlet glaciers since the 2000s has led to the formation of several glacial lakes. Processes causing the formation and ... -
Microstructurally-constrained versus bulk fault gouge K-Ar dating
Scheiber, Thomas; Viola, Giulio; van der Lelij, Roelant; Margreth, Annina; Schönenberger, Jasmin (Peer reviewed; Journal article, 2019)Structural, mineralogical and geochronological data were collected from two brittle fault zones (Fault I and II) deforming the Ordovician Rolvsnes granodiorite in SW Norway. Microstructurally-constrained K–Ar data from ... -
Multimodal Asynchronous Kalman Filter for monitoring unstable rock slopes
Schild, Lukas; Scheiber, Thomas; Snook, Paula; Arghandeh, Reza; Samnøy, Stig Frode; Maschler, Alexander; Kristensen, Lene (Peer reviewed; Journal article, 2023)Unstable rock slopes pose a hazard to inhabitants and infrastructure in their vicinity, necessitating advanced monitoring methodologies for timely risk assessment and mitigation. Recent geotechnical monitoring techniques ... -
Rapid post-glacial bedrock weathering in coastal Norway
Andersen, Jane Lund; Margreth, Annina; Fredin, Ola; Linge, Henriette; Goodfellow, Bradley W.; Faust, Johan Christoph; Knies, Jochen; Solbakk, Terje; Brook, Edward J.; Scheiber, Thomas; van der Lelij, Roelant; Burki, Valentin Josef; Rubensdotter, Brita Lena Eleonor Fredin; Himmler, Tobias; Yesilyurt, Serdar; Christl, Marcus; Vockenhuber, Christof; Akcar, Naki (Peer reviewed; Journal article, 2021)Quantifying bedrock weathering rates under diverse climate conditions is essential to understanding timescales of landscape evolution. Yet, weathering rates are often difficult to constrain, and associating a weathered ...
