Fault-controlled fluid circulation and diagenesis along basin-bounding fault systems in rifts - Insights from the East Greenland rift system
Salomon, Eric; Rotevatn, Atle; Kristensen, Thomas Berg; Grundvåg, Sten-Andreas; Henstra, Gijs Allard; Meckler, Anna Nele; Albert, Richard; Gerdes, Axel (Journal article; Peer reviewed, 2020-11-05)In marine rift basins, deep-water clastics (>200 m) in the hanging wall of rift- or basin-bounding fault systems are commonly juxtaposed against crystalline “basement” rocks in the footwall. A distinct feature of such fault ... -
Microstructure and fluid flow in the vicinity of basin bounding faults in rifts – The Dombjerg Fault, NE Greenland rift system
Salomon, Eric; Rotevatn, Atle; Kristensen, Thomas Berg; Grundvåg, Sten-Andreas; Henstra, Gijs Allard (Journal article; Peer reviewed, 2021)Faults commonly form loci for high fluid flux in sedimentary basins, where fluids, rocks and deformation processes frequently interact. Here, we elucidate the interaction of fluid flow, diagenesis and deformation near ... -
Pre-existing intra-basement shear zones on the development of non-colinear rift fault network, Utsira High – Heimdal Terrace, North Sea
Osagiede, Edoseghe Edwin; Rotevatn, Atle; Gawthorpe, Rob; Kristensen, Thomas Berg; Jackson, Christopher; Marsh, Nicola (Peer reviewed; Journal article, 2020)Pre-existing intra-basement shear zones can induce mechanical and rheological heterogeneities that may influence rifting and the overall geometry of rift-related normal faults. However, the extent to which physical and ... -
The role of structural inheritance in the development of high-displacement crustal faults in the necking domain of rifted margins: The Klakk Fault Complex, Frøya High, offshore mid-Norway
Munoz Barrera, Jhon Meyer; Rotevatn, Atle; Gawthorpe, Rob; Henstra, Gijs Allard; Kristensen, Thomas Berg (Journal article; Peer reviewed, 2020-08-20)The role of inherited structures during the development of normal faults in continental rifts and proximal domains of passive margins have been extensively studied. Few studies, however, have a focus on deciphering the ... -
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 ...
