Repeated brittle reactivations of a pre-existing plastic shear zone: combined K-Ar and ⁴⁰Ar-³⁹Ar geochronology of the long-lived (>700 Ma) Himdalen-Orje Deformation Zone, SE Norway. Geological Magazine. ISSN 0016-7568. 159(11-12), s. 2110–2131. doi: 10.1017/S0016756822000966. Fulltekst i vitenarkiv Vis sammendrag

  Brittle reactivation of plastic shear zones is frequently observed in geologically old terranes. To better understand such deformation zones, we have studied the >700 Ma long structural history of the Himdalen–Ørje Deformation Zone (HØDZ) in SE Norway by K–Ar and 40Ar–39Ar geochronology, and structural characterization. Several generations of mylonites make up the ductile part of HØDZ, the Ørje Shear Zone. A 40Ar–39Ar white mica plateau age of 908.6 ± 7.0 Ma constrains the timing of extensional reactivation of the Ørje mylonite. The mylonite is extensively reworked during brittle deformation events by the Himdalen Fault. 40Ar–39Ar plateau ages of 375.0 ± 22.7 Ma and 351.7 ± 4.4 Ma from pseudotachylite veins and K–Ar ages of authigenic illite in fault gouge at c. 380 Ma are interpreted to date initial brittle deformation, possibly associated with the Variscan orogeny. Major brittle deformation during the Early–Mid Permian Oslo Rift is documented by a 40Ar–39Ar pseudotachylite plateau age of 294.6 ± 5.2 Ma and a K–Ar fault gouge age of c. 270 Ma. The last datable faulting event is constrained by the finest size fraction in three separate gouges at c. 200 Ma. The study demonstrates that multiple geologically significant K–Ar ages can be constrained from fault gouges within the same fault core by combining careful field sampling, structural characterization, detailed mineralogy and illite crystallinity analysis. We suggest that initial localization of brittle strain along plastic shear zones is controlled by mechanical anisotropy of parallel-oriented, throughgoing phyllosilicate-rich foliation planes within the mylonitic fabric.

  On Varanger Peninsula, the roughly NW–SE-trending Trollfjorden–Komagelva Fault Zone separates Neoproterozoic successions that accumulated in a shallow-marine platformal domain to the SW of the fault from deepmarine basinal to deltaic sediments to the NE. In Ediacaran time the fault scarp acted as a buttress in a period of basinal inversion during the top-to-the-SW, contractional Timanian orogeny. During the subsequent, top-to-the-SE to -ESE, polyphase Caledonian orogenesis the fault acted as a dextral strike-slip megafracture and lateral ramp. In the northeastern terrane, Timanian and Caledonian fold interference has produced several examples of double-folding and intersecting cleavages. In the southwestern terrane, the Lower Allochthon Gaissa Thrust Belt overlies the Parautochthon, below which a 45 km long deformation front has been mapped. Tectonic shortening within this frontal zone varies from top-to-the-SSE in the west to topto-the-ESE in the east. Imbricate thrust sheets disrupt the succession in the northeastern terrane, below which a floor décollement is speculated to emerge as a frontal fault along a prominent footwall of the precursor fault that acted on the seabed in outermost Varangerfjorden. By use of potential field data, the Caledonian structures on Varanger can be followed to the north into the Barents Sea where the nappe pile in the pre-Carboniferous basement reaches a thickness of several kilometres.

  An extensive, reprocessed two-dimensional (2D) seismic data set was utilized together with available well data to study the Tiddlybanken Basin in the southeastern Norwegian Barents Sea, which is revealed to be an excellent example of base salt rift structures, evaporite accumulations and evolution of salt structures. Late Devonian–early Carboniferous NE-SW regional extensional stress affected the study area and gave rise to three halfgrabens that are separated by a NW-SE to NNW-SSE trending horst and an affiliated interference transfer zone. The arcuate nature of the horst is believed to be the effect of pre-existing Timanian basement grain, whereas the interference zone formed due to the combined effect of a Timanian (basement) lineament and the geometrical arrangement of the opposing master faults. The interference transfer zone acted as a physical barrier, controlling the facies distribution and sedimentary thickness of three-layered evaporitic sequences (LES). During the late Triassic, the northwestern part of a salt wall was developed due to passive diapirism and its evolution was influenced by halite lithology between the three-LES. The central and southeastern parts of the salt wall did not progress beyond the pedestal stage due to lack of halite in the deepest evaporitic sequence. During the Triassic–Jurassic transition, far-field stresses from the Novaya Zemlya foldand- thrust belt reactivated the pre-salt Carboniferous rift structures. The reactivation led to the development of the Signalhorn Dome, rejuvenated the northwestern part of the salt wall and affected the sedimentation rates in the southeastern broad basin. The salt wall together with the Signalhorn Dome and the Carboniferous pre-salt structures were again reactivated during post-Early Cretaceous, in response to regional compressional stresses. During this main tectonic inversion phase, the northwestern and southeastern parts of the salt wall were rejuvenated; however, salt reactivation was minimized towards the interference transfer zone beneath the centre of the salt wall.

  High quality reprocessed seismic reflection profiles and available wells were used to study the little studied southeastern Norwegian Barents Sea and east Finnmark Platform. The study area comprises prominent structural elements such as the Haapet, Veslekari, and Signalhorn domes, the West Fedynsky High, and the Tiddlybanken and Nordkapp basins. Seven deep-seated Carboniferous grabens, not formally described earlier, were defined and informally named; and similarly, five evaporite bodies that are tapered stratigraphically above the grabens have been mapped in detail. In the late Devonian, the region comprised a central structural high (Fedynsky High), and two depressions to the north and south, and has subsequently experienced transtensional deformation during a late Devonian-early Carboniferous NE-SW regional extensional phase. As a result, a NW-SE trending graben system was created over the paleotopography, following the inherited Timanian orogeny lineaments and giving rise to the deep-seated Carboniferous grabens. Pennsylvanian to early Permian evaporites were deposited and were characterized by mobile and non-mobile lithologies. The Carboniferous structures controlled the volume, thickness and lithological alterations of the evaporites, and have later influenced the distribution and development of the salt wall and domes. The Haapet, Veslekari, composite West Fedynsky (two domes informally named Alpha and Beta) and Signalhorn domes were generated and the salt wall of the Tiddlybanken Basin was rejuvenated during the late Triassic due to compressional stresses propagating from the evolving Novaya Zemlya fold-and-thrust belt. The domes and salt wall were subsequently reactivated during the upper Jurassic and earliest Cretaceous. Furthermore, we infer that the main phase of reactivation of these structures took place during the early-middle Eocene due to far-field stresses from the transpressional Eurekan/Spitsbergen orogeny.

  Geological storage of CO2 is a key technical solution to the climate-energy challenge, but it has a number of technological constraints (Baines and Worden 2004; Halland et al., 2011), broadly under the themes of assuring adequate storage capacity and long-term storage integrity. A suitable CO2-storage reservoir should consist of rock formations with sufficient porosity, permeability and connectivity in order to provide an adequate storage volume. The role of faults and their associated deformation structures (such as deformation bands and fractures) in controlling both storage capacity and long-term storage integrity is thus a key factor in achieving globally significant CO2 storage (Figure 1). Although some sedimentary basins on the Norwegian continental shelf already harbour operational CO2- injection and storage projects such as Sleipner (Zweigel et al., 2004) and Snøhvit (Hansen et al., 2013), our understanding of reservoir fluid communication due to compartmentalization is far from complete and will be important for further use of the offshore basins for CO2 storage. In addition to the inherited structural features, elevated injection pressures may cause hydraulic fractures or stimulate fault reactivation which both point to the need to characterize the geomechanical response of the rock system to CO2 injection (Rutqvist, 2012; Iding and Ringrose, 2010). In the present work, we investigate the effects of faults and their related structures on the geomechanical and petrophysical properties of sandstone reservoirs. Important components of fault systems include fractures and deformation bands in the damage zone and fault core (Caine et al., 1996; Shipton and Cowie, 2003; Fossen et al., 2007). Fault systems may enhance or suppress fluid communication, which in turn may affect the storage capacity and conductivity of the candidate reservoirs (Figure 1). As a case study, a reservoir model of the Tubåen Formation at the Snøhvit CO2 injection site in the Barents Sea (Grude et al., 2013; Hansen et al., 2013) was investigated using 4D seismic data and fault attribute analysis. The characteristics of deformation structures (e.g. sub-seismic faults, deformation bands and fractures) were investigated by field studies of outcrop analogues and by triaxial laboratory experiments to provide a basis for numerical modelling. Fault architecture within reactivated fault systems was studied by the use of analogue modelling. Key questions addressed in the work include: a) Where and when might strain localize in the reservoir? b) How does rock strain influence fluid communication? c) How might structural architecture affect CO2 storage effectiveness?

  Reprocessed regional 2D seismic reflection profiles, 3D seismic data, available wells, and gravity and magnetic data, together with basin modelling are utilised to comprehend the pre-salt Carboniferous rift architecture and supra-salt evolution of the Nordkapp Basin (study area: ~150000 sqkm). The Nordkapp Basin evolved over a basement that had been affected by complex interaction between the Timanian and Caledonian structural elements. During the late Devonian-early Carboniferous NE-SW-oriented extension, the Nordkapp Basin consisted of a northern and a southern regional half-graben separated by an elevated interbasin ridge. During the late Carboniferous-early Permian, a second extension phase took place with a shift in stress orientation to NW-SE that influenced the two regional half-grabens and caused the development of seven sub-basins separated by interbasin transfer zones in the Nordkapp Basin. The relative depth of each sub-basin, the arrangement of structural highs along with evolving master faults and depositional paleo-environment all controlled the thickness and facies of syn-rift layered evaporitic sequences (LES). Some remnant topography existed in the Nordkapp Basin in the earliest Triassic, when a regional prograding system arrived from the east causing differential loading and triggering the salt movements, which in turn created significant local topography with mini-basins surrounding the growing salt structures. The resulting composite basin topography strongly influenced the Triassic progradational sediment routings and dictated both where the initial deposition could take place and the formation of distinct depositional fairways. Basin modelling and structural restoration have revealed that once the mobile salt depleted from the syn-rift LES beneath the axial zone then the salt structure was sourced from depocenter opposite to it. The salt structures were slightly rejuvenated due to the reactivation of the Carboniferous structures caused by the far-field stresses propagating during late Triassic in response to the evolving Novaya Zemlya fold-and-thrust belt farther to the east. The salt was depleted from the synrift LES by the early Cretaceous as the prograding shelf platform complex buried the salt structures. The main phase of rejuvenation of the salt structures took place during the early-middle Eocene as a result of the transpressional Eurekan/Spitsbergen orogeny farther to the northwest until the Cenozoic uplift eroded most of the post-middle Cretaceous sediments. The spatially diverse salt structures affected the late Permian to Cenozoic supra-salt sedimentary strata in the Nordkapp Basin which offers an excellent environment to study the distinct supra-salt structural styles, including turtle structures, secondary and thrusted welds, bowl vs wedge geometries, collided and secondary mini-basins, salt wings and megaflaps.

  The study utilised reprocessed regional 2D seismic reflection profiles, 3D seismic data, available wells and basin modelling to reveal the controlling factors for the supra-salt sedimentary evolution of the northeastern, central and southwestern segments of the Nordkapp Basin. The basin offers an excellent environment for the study of diverse supra-salt structural styles, including turtle structures, secondary squeezed and thrusted welds, collided mini-basins, bowl vs wedge geometries, salt wing and megaflap. The observed salt structures show different sizes, shapes, orientations and lateral extent that affect the late Permian to Cenozoic supra-salt sedimentation in the Nordkapp Basin. Some remnant topography existed in the Nordkapp Basin in the earliest Triassic related to the underlying late Devonian to early Carboniferous (NE-SW) and late Carboniferous to early Permian (NW-SE) extension structures that overprinted on the contrasting Timanian and Caledonian basement structural grains. A regional prograding system arrived from the east causing differential loading and triggering of salt movements, which in turn created significant local topography with mini-basins surrounding the growing salt structures. The resulting basin topography strongly influenced the Triassic progradational sediment routings and dictated both where the initial deposition could take place and the formation of distinct depositional fairways. The depositional fairways primarily formed by differential loading and density-driven subsidence caused by the progradational sedimentation, and have restricted the subsidence in the mini-basins outside the fairways. Once the mobile salt was depleted from the layered evaporitic sequences (LES) beneath the axial zone then the salt structure was sourced from the depocenter opposite to it. The salt was evacuated from the LES diachronically along the strike of the basin as the earliest passive diapirism occurred in the northeastern segment and then progressed to the central segment due to the direction of progradation of the approaching deltaic system. We suggest that the direction and the velocity of the prograding system arriving from the east filled the initial depositional fairways over the syn-rift LES and the pre-salt rift architecture thus defined the sedimentary depositional architecture within the Nordkapp Basin. The salt structures were slightly rejuvenated due to the reactivation of the Carboniferous structures caused by the far-field stresses propagating during late Triassic in response to the evolving Novaya Zemlya fold-and-thrust belt farther to the east. The salt was depleted from the LES by the early Cretaceous as the prograding shelf platform complex buried the salt structures. The main phase of rejuvenation of the salt structures took place during the early-middle Eocene as a result of the transpressional Eurekan/Spitsbergen orogeny farther to the northwest until the Cenozoic uplift eroded most of the post-middle Cretaceous sediments.

  Reprocessed regional 2D seismic reflection profiles, 3D seismic data, available wells, and gravity and magnetic data were used to study the pre-salt rift architecture in the Nordkapp Basin, Barents Sea, and its impact on the evaporite accumulations and distribution of salt structures. The basin is subdivided into three main segments (the northeastern, central, and southwestern sub-basins) and has evolved over the complex interaction between the Timanian and Caledonian structural basement grains. Each segment is characterized by prominent magnetic anomalies related to the Timanian and Caledonian structural inheritance. The rotated magnetic lineations associated with the Caledonian structures beneath the Finnmark Platform pass through the central segment, where the Middle Allochthonous Front creates the major sub-division between the two structural grains. We suggest that the rheological properties, locations, orientations and interaction of the parts of the basement influenced by Timanian and Caledonian structural grains together with two subsequent extensional phases, have strongly influenced the shallower pre-salt rift architecture. During the late Devonian – early Carboniferous NE-SW -oriented extensional phase, the Nordkapp Basin consisted of a northern and a southern regional halfgraben separated by an elevated interbasin ridge. The hinged margins of the northern and southern regional half-grabens were restricted against the NW-SE-striking graben beneath the Veslekari Dome and Troms- Finnmark Fault Complex, respectively. The internal configuration of the regional half-grabens was affected by the NW-SE-striking master faults. During the late Carboniferous to early Permian, a second extension phase took place with a shift in stress orientation to NW -SE and influenced the two regional half-grabens. In particular, a transfer fault with the character of an interbasin transfer zone (the northern transfer zone) divided the northern regional half-graben by separating its hinged margin (incipient northeastern segment) from the deeper part (incipient central segment). At the same time, the elevated interbasin ridge acted as a southern transfer zone, separating the incipient central and southwestern segments of the Nordkapp Basin. The Thor Iversen, Polstjerna, Måsøy and Nysleppen basin border fault systems were formed during the second extensional phase and reshaped the internal configuration of the two regional half-grabens. The structural interaction between the spatially variable Timanian and Caledonian structural grains overprinted by two subsequent phases of NE-SW and NW-SE extension caused the development of seven sub-basins in the Nordkapp Basin. Internally within the sub-basins, the evolving structural elements including cross-cutting master faults and structural highs have influenced the deposition and facies of the layered evaporitic sequences and defined the location of subsequent salt structures. We suggest that the relative depth of each sub-basin, the arrangement of structural highs along with the evolving master faults and the depositional paleo-environment all controlled the thickness and facies of the syn-rift layered evaporitic sequences.

  Improved resolution reprocessed 2D multi-channel seismic reflection profiles, combined with exploration wells and stratigraphic boreholes penetrating upper Paleozoic sequences on the eastern Finnmark Platform were utilized particularly to analyse the Carboniferous graben system, evaporite bodies distribution, domes and salt wall in the southeastern Norwegian Barents Sea and east Finnmark Platform. Seven deep-seated Carboniferous grabens, not previously described and named, were defined and informally named as grabens G1-G7. Five evaporite bodies, named EB1-EB5, have been mapped in detail. During late Devonian, the study area was dominated by a central structural high region (Fedynsky High) rimmed by sag basins to the north and south it. We suggest that late Devonian-early Carboniferous (Mississippian) NE-SW oriented stress regime as suggested for the evolution of the Pechora Basin, eastern Barents Sea, and Olga-Sørkapp region also created the NW-SE striking graben structures (G1-G5) in the southeastern Norwegian Barents Sea, mainly exploiting the Timanian Orogen structural grain. In the early Pennsylvanian, the NE-SW trending Nordkapp Basin dissected the already existing G6 and G7 grabens. Pennsylvanian to early Permian evaporite units were deposited. The temporal relationship suggests that the evaporites were deposited as post-rift sequences within the Carboniferous grabens of the southeastern Norwegian Barents Sea and as syn-rift or early post-rift sequences within the Nordkapp Basin. The discrepancy in syn-rift to post-rift basin conditions affected the distribution and thickness of the accumulated evaporites, partly or fully occupying the available accommodation space. Evaporite bodies EB1, EB3, and EB5 are correlated to the Gipsdalen Group halite and non-halite lithologies (i.e. anhydrite-related compositions) with less thickness, while evaporite body EB4 contained mobile halite lithology and EB2 comprised of transitional lithology from graben margin (non-mobile) to the center (mobile). The deep-seated structures constrained the accumulation and facies variations of the evaporites and strongly controlled the distribution and partially the evolution of the stratigraphically shallower domes. The effect of salt mobilization on the dome evolution depended on the relative amount of lithologies with mobile to immobile properties, and the relative stratigraphic thickness of each unit. The NW-SE trending salt wall evolution is complex, varies along-strike, and has affected the structural development of the Signalhorn Dome that was instigated during late Triassic due to the far-field stresses from the evolving Novaya Zemlya fold-and-thrust belt. The Haapet, Veslekari, Alpha and Beta domes were instigated and the salt wall was rejuvenated during late Triassic due to compressional stresses propagating from the Novaya Zemlya fold-and-thrust belt as these structures were located in the relative proximity. Several studies on the Barents Sea-Svalbard region have similarly recorded the results of far-field compressional stresses attributed to the Novaya Zemlya fold-and-thrust belt. All of the structural elements were mildly reactivated during upper Jurassic and earliest Cretaceous. However, the exact causes of this reactivation are difficult to be deciphered in detail due to lack of dense seismic reflection coverage and relatively poor seismic resolution in the southeastern Norwegian Barents Sea. Prograding shelf platform complex sediments during early Cretaceous buried the domes and the salt wall until reactivation of the deep-seated Carboniferous grabens led to the reactivation of these structures and to the erosion of the post-lower Cretaceous strata over their crest. We infer an early-middle Eocene timing for the main phase of reactivation of the domes and salt wall, probably in response to regional compressional stresses related to the transpressional Eurekan/Spitsbergen orogeny

  2D regional seismic reflection profiles and well data are used for the investigation of the deep basin architecture in the southeastern Norwegian Barents Sea. The study area contains thick upper Paleozoic to Mesozoic sedimentary strata with prominent structural features comprising the Haapet, Veslekari, and Signalhorn Domes; the Tiddlybanken Basin, Fedynsky High, and eastern Finnmark Platform. Interpretation of selected seismic profiles and time structure maps are presented focusing on the positions, extent, and configurations of the Carboniferous basins. Furthermore, we investigate the relation between the Carboniferous graben structures, evaporites accumulations and inversion in the area. The basin boundary faults of the Carboniferous structures strike NW-SE, and the syn-rift Carboniferous sequences were deposited in half and full grabens. Basins are separated by platforms and structural highs, while basin infill generally dips towards the axis of the grabens, except for the half-graben on the Finnmark Platform where strata dip towards the north and the half-grabens beneath the Haapet Dome where strata dip to the south. In the study area, evaporites are accommodated in the Carboniferous basins and carbonates occupy the structural highs. The deposition of evaporites was constrained by the master faults of the grabens, except for an evaporitic body, which oversteps the rift margins and connects with the southeastern and central parts of the Nordkapp Basin. Furthermore, a thick Triassic succession, with provenance mainly in the southeast, was deposited in the region, while thin Jurassic sediments outcrop at seafloor over the Veslekari Dome and the salt diapir of the Tiddlybanken Basin. Prograding Cretaceous strata mark another phase of regional subsidence in the study area. Several domes are identified in the near base Triassic to the base Cretaceous levels with different shapes, orientation and sizes. The distribution and evolution of the younger domes are partially controlled by the deep-seated Carboniferous structures. Distinct observations including the lateral thickness variations for the uppermost Triassic to the lowermost Cretaceous sediments, the rim syncline development and the onlap at various stratigraphic levels all suggest several phases of doming. We propose a Paleogene timing for the main phase of reactivation of the inverted domes due to Carboniferous graben structures, probably in response to regional compressional stresses.

  2D regional seismic reflection profiles and well data were used for the mapping of the deep Carboniferous basin architecture in the southeastern Norwegian Barents Sea. Interpretation of selected seismic profiles and time structure maps are presented focusing on the positions, configurations and deformation stages of these basins. Furthermore, we investigate the connection between the Carboniferous graben structures, evaporites accumulations and reactivation of the younger domes in the area. The basin boundary faults and affiliated depo-centers of the Carboniferous structures strike NW-SE, defining structural configurations consisting of half- and full grabens. The basins are separated by platforms and structural highs. The basin fill generally dips towards the axis of the grabens, except for the half-graben on the Finnmark Platform, where strata dip towards the north and the half-grabens beneath the Haapet Dome where strata dip to the south. Evaporites are accommodated in the Carboniferous basins and carbonates occupy the structural highs. The deposition of evaporites was constrained by the master faults of the grabens, except for one evaporite body, which oversteps the rift margins and connects with the southeastern and central parts of the Nordkapp Basin. Several domes are identified at the near base Triassic to the base Cretaceous levels. These have different shapes, orientation and sizes. The distribution and evolution of the younger domes are partially controlled by the deep-seated Carboniferous structures. Lateral thickness variations for the uppermost Triassic to the lowermost Cretaceous sediments, the rim syncline development and the onlap at various stratigraphic levels, all suggest several phases of doming. We propose a Paleogene timing for the main phase of reactivation of the domes due to Carboniferous graben structures, probably in response to regional compressional stresses.

  The doctoral thesis is a collection of four published journal papers, which investigate the influence of the basement inheritance on the pre-salt basin configuration and its effects on the accumulation of the layered evaporite sequence, salt tectonics and post-salt sedimentation in evaporite-influenced rift basins. The thesis has shown that rheological properties, locations, orientation and interaction of inherited structures created zones of weakness that influenced the development of complex pre-salt basin architecture along with subsequent regional extensional phases. Consequently, the syn-rift to post-rift processes within discrete accommodation space of varying depth and depositional paleo-environment, have influenced the thickness and facies (mobile to non-mobile) of the layered evaporite sequence. The study highlights that the regional extension and prograding sediment influx direction, the sediment transport velocity and the sediment thickness influenced the dynamics of the early to late passive diapirism, the salt expulsion and the depletion, together with the layered evaporite thickness and facies that were affected by the pre-salt rift architecture. The salt structures and evaporite-cored domes were rejuvenated due to far-field contractional stresses and eventually uplift eroded the successions over their crests.
