Sequential growth of deformation bands in carbonate grainstones in the hangingwall of an active growth fault: Implications for deformation mechanisms in different tectonic regimes
Rotevatn, Atle; Thorsheim, Elin; Bastesen, Eivind; Fossmark, Heidi Synnøve Solli; Torabi, Anita; Sælen, Gunnar (Peer reviewed; Journal article, 2016-09)Deformation bands in porous sandstones have been extensively studied for four decades, whereas comparatively less is known about deformation bands in porous carbonate rocks, particularly in extensional settings. Here, we ... -
Spatial variability in topology, connectivity and permeability of deformation band networks: Insights from the Jurassic Entrada Sandstone, Utah
Heggernes, Hakan; Rotevatn, Atle; Demurtas, Matteo; Nixon, Casey William; Fossen, Haakon (Journal article; Peer reviewed, 2023)Networks of deformation bands have the potential to act as baffles to fluid flow, yet little work has been devoted to addressing their network properties, such as topology and connectivity. Motivated by this, we investigate ... -
Strain migration during multiphase extension, Stord Basin, northern North Sea rift
Fazlikhani, Hamed; Aagotnes, Synne; Refvem, Marte; Hamilton-Wright, James; Bell, Rebecca E.; Fossen, Haakon; Gawthorpe, Rob; Jackson, Christopher A.-L.; Rotevatn, Atle (Journal article; Peer reviewed, 2021)In regions experiencing multiple phases of extension, rift‐related strain can vary along and across the basin during and between each phase, and the location of maximum extension can differ between the rift phase. Despite ... -
Structural evolution of sheared margin basins: the role of strain partitioning. Sørvestsnaget Basin, Norwegian Barents Sea
Kristensen, Thomas Berg; Rotevatn, Atle; Marvik, Maria; Henstra, Gijs Allard; Gawthorpe, Robert; Ravnås, Rodmar (Peer reviewed; Journal article, 2017)Spatio-temporal analysis of basins formed along sheared margins has received much less attention than those formed along orthogonally extended margins. Knowledge about the structural evolution of such basins is important ... -
Structural inheritance and rapid rift-length establishment in a multiphase rift: The East Greenland rift system and its Caledonian orogenic ancestry
Rotevatn, Atle; Kristensen, Thomas Berg; Ksienzyk, Anna Katharina; Wemmer, Klaus; Henstra, Gijs Allard; Midtkandal, Ivar; Grundvåg, Sten-Andreas; Andresen, Arild (Peer reviewed; Journal article, 2018-06)We investigate (i) margin‐scale structural inheritance in rifts and (ii) the time scales of rift propagation and rift length establishment, using the East Greenland rift system (EGR) as an example. To investigate the ... -
Structure and flow properties of syn-rift border faults: The interplaybetween fault damage and fault-related chemical alteration (Dombjerg Fault, Wollaston Forland, NE Greenland)
Kristensen, Thomas Berg; Rotevatn, Atle; Henstra, Gijs Allard; Peacock, David; Midtkandal, Ivar; Grundvåg, Sten-Andreas (Peer reviewed; Journal article, 2016-11)Structurally controlled, syn-rift, clastic depocentres are of economic interest as hydrocarbon reservoirs; understanding the structure of their bounding faults is of great relevance, e.g. in the assessment of fault-controlled ... -
Supradetachment basins in necking domains of rifted margins: Insights from the Norwegian Sea
Munoz Barrera, Jhon Meyer; Rotevatn, Atle; Gawthorpe, Robert Leslie; Henstra, Gijs Allard; Berg Kristensen, Thomas (Journal article; Peer reviewed, 2022)Supradetachment basins at passive rifted margins are a key witness of major-continental extension, and they may preserve a record from which the amount and rates of extension and metamorphic core complex exhumation may be ... -
Syn-rift sediment gravity flow deposition on a Late Jurassic fault-terraced slope, northern North Sea
Tillmans, Fabian; Gawthorpe, Robert Leslie; Jackson, Christopher AL; Rotevatn, Atle (Journal article; Peer reviewed, 2021)Structurally controlled bathymetry in rifts has a significant influence on sediment routing pathways and depositional architecture of sediment gravity flow deposits. In contrast to rift segments characterized by crustal-scale ... -
Topological Characterization of a Fault Network Along the Northern North Sea Rift Margin
Osagiede, Edoseghe Edwin; Nixon, Casey William; Gawthorpe, Rob; Rotevatn, Atle; Fossen, Haakon; Jackson, Christopher A.-L.; Tillmans, Fabian (Journal article; Peer reviewed, 2023)The factors that control the spatial variation of the topological characteristics of normal fault networks at the rift-scale are poorly understood. Here, we use 3D seismic reflection data from the northern North Sea to ... -
Tracing Lower Cretaceous organic-rich units across the SW Barents Shelf
Hagset, Andreas Hallberg; Grundvåg, Sten-Andreas; Badics, Balazs; Davies, R; Rotevatn, Atle (Journal article; Peer reviewed, 2022)On the Barents Shelf, the northernmost and least explored hydrocarbon province of the Norwegian Continental Shelf, Upper Jurassic organic-rich shales have traditionally been given most attention as these represent the most ... -
Turbidites, topography and tectonics: Evolution of submarine channel-lobe systems in the salt-influenced Kwanza Basin, offshore Angola
Howlett, Danielle; Gawthorpe, Rob; Ge, Zhiyuan; Rotevatn, Atle; Jackson, Christopher A.-L. (Journal article; Peer reviewed, 2021)Understanding the evolution of submarine channel‐lobe systems on salt‐influenced slopes is challenging as these systems react to subtle, syn‐depositional changes in sea‐floor topography. The impact of large blocking ...
