“…The tectonic history of the western Barents Sea (Figure 2.1) can be traced back to the Caledonian Orogeny that strikes through northernmost Norway and northeastwards into the Barents Shelf (Barrère et al, 2009;Breivik et al, 2005Breivik et al, , 2002Gee et al, 2008;Gernigon and Brönner, 2012;Gernigon et al, 2014;Gudlaugsson et al, 1998;Marello et al, 2013;Ritzmann and Faleide, 2007;Roberts, 2003). The Caledonian fabric is obscured in most parts of Barents Sea, except on Svalbard by late Proterozoic and Mesozoic sedimentary basins (Breivik et al, 2002;Gee et al, 2008).…”

High-quality 3D seismic data are used to analyze the history of fault growth and hydrocarbon leakage in the Snøhvit Field, southwestern Barents Sea. The aim of this work is to evaluate the role of tectonic fracturing as a mechanism driving fluid-flow in the study area. To achieve this aim, an integrated approach including seismic interpretation, multiple seismic attribute analysis, fault modeling and displacement analysis was used.The six major faults in the study area are dip-slip normal faults which are characterized by complex lateral and vertical segmentation. The three main episodes of fault reactivation interpreted were in late Jurassic (Kimmeridgian), early Cretaceous and Paleocene times. Fault reactivation in the study area is mainly through dip-linkage. Throw-distance plots of the representative faults also revealed along-strike linkage and multi-skewed C-type profiles. The throw profiles show that faults in the study area evolved through polycyclic activity involving both blind propagation, syn-sedimentary activity and that they have their maximum displacement at the reservoir zone. The expansion and growth indices provide evidence for coeval fault activity with sedimentation and interaction of the faults with a free surface during their evolution.

“…The graben in the Hammerfest Basin has been affected by the extensional tectonics in the Carboniferous (Berglund et al, 1986) and further evolved during the Caledonian orogenic collapse (Gernigon et al, 2014;Ritzmann and Faleide, 2007). This causes tilting of the Loppa Bathonian-Callovian unconformity .…”

“…Deep Cretaceous basins and Late Cretaceous-Palaeocene normal faulting are also known from the southwest Barents Sea margin (Gabrielsen et al, 1990;Faleide et al, 1993Faleide et al, , 2008Faleide et al, , 2010Clark et al, 2013;Gernigon et al, 2014;Safronova et al, 2015). Breivik et al (1998) reported significant Late Cretaceous-Early Palaeogene normal faulting along the southwestern margin of the Barents Sea with offsets of up to 1 km on individual faults and a cumulative offset of 9 km based on recognition of a 'mid' Cretaceous reflector.…”

“…The thick Cretaceous sedimentary package and the possible Aptian-Albian and postConiacian activity on the Kilen faults resemble the pattern observed on the conjugate southwest Barents Sea margin in the Harstad, Tromsø, Bjørnøya, Sørvestnaget and Hammerfest basins (Gabrielsen et al, 1990). In particular, the northern part of the Bjørnøya Basin (Gabrielsen et al, 1990;Clark et al, 2013;Gernigon et al, 2014) has a strong resemblance to the basin at Kilen and the two areas were only 100-200 km apart in preopening times ( Fig. 7; Müller et al, 2016).…”

“…This structural model allows for a new and simpler view of the Mesozoic Wandel Sea Basin as a rift basin dominated by extensional faults; in line with basins along the conjugate southwestern Barents Sea margin such as the Bjørnøya, Sørvestnaget and Tromsø basins (Faleide et al, 2008;Gernigon et al, 2014). This paper explores the implications of this new tectonic model for Mesozoic basin evolution by presenting a pre-folding 3D reconstruction of the basin at Kilen using the structural model of Svennevig et al (2016a).…”

The semi-nunatak Kilen is a key area to understand the setting of the Cretaceous sedimentary basin in eastern North Greenland. The basin geometry has been obscured by later N-S compression and inversion of presumable Palaeocene-Eocene age. A 3D restoration of the Cretaceous basin is presented based on new oblique photogrammetry and field data combined with published data. The 3D restoration focuses on the main faults and a well constrained mid-Cretaceous horizon. The restoration shows that the horizon was offset down-to-the-ENE by several NNW-SSE-striking normal faults and highlights the similarity of the pre-folding basin to a normal rifted margin. The northwestern part of the restored area comprises five fault blocks divided by four NNW-SSE-striking normal faults dipping to the ENE, whereas the southeastern part consists of a single large fault block deformed by minor antithetic faulting. Minimum offsets on exposed normal faults are between 780 and 1200 m, and the fault blocks are between 1.5 and more than 10 km in width. The restoration and interpretation of the Cretaceous basin at Kilen as extensional opens for a similar interpretation for NNW-SSE-oriented faults affecting Mesozoic sediments elsewhere in the Wandel Sea Basin which were previously interpreted as having formed in a strike-slip setting. The basin restored at Kilen has several similarities to basins on the southwestern Barents Sea margin, especially the Bjørnøya Basin, located just 100-200 km east of Kilen in pre-North Atlantic opening times. The two basins were separated by the Stappen High and the basin at Kilen could be the western part of a successful rift that eventually resulted in the opening of the North Atlantic.

Formation and deformation of hyperextended rift systems: Insights from rift domain mapping in the Bay of Biscay-Pyrenees

et al. 2014

The Bay of Biscay and the Pyrenees correspond to a Lower Cretaceous rift system including both oceanic and hyperextended rift domains. The transition from preserved oceanic and rift domains in the West to their complete inversion in the East enables us to study the progressive reactivation of a hyperextended rift system. We use seismic interpretation, gravity inversion, and field mapping to identify and map former rift domains and their subsequent reactivation. We propose a new map and sections across the system illustrating the progressive integration of the rift domains into the orogen. This study aims to provide insights on the formation of hyperextended rift systems and discuss their role during reactivation. Two spatially and temporally distinct rift systems can be distinguished: the Bay of Biscay-Parentis and the Pyrenean-Basque-Cantabrian rifts. While the offshore Bay of Biscay represent a former mature oceanic domain, the fossil remnants of hyperextended domains preserved onshore in the Pyrenean-Cantabrian orogen record distributed extensional deformation partitioned between strongly segmented rift basins. Reactivation initiated in the exhumed mantle domain before it affected the hyperthinned domain. Both domains accommodated most of the shortening. The final architecture of the orogen is acquired once the conjugate necking domains became involved in collisional processes. The complex 3-D architecture of the initial rift system may partly explain the heterogeneous reactivation of the overall system. These results have important implications for the formation and reactivation of hyperextended rift systems and for the restoration of the Bay of Biscay and Pyrenean domains.
