Abstract Deep seismic data from the Hatton-Rockall region, mid-Norway margin and SW Barents Sea provide images of crustal structure that make it possible to estimate relative amounts thinning for Late Jurassic-Cretaceous Maastrichtian-Paleocene NE Atlantic rift episodes. In addition, plate reconstructions illustrate movements between Eurasia Greenland back Mid-Jurassic time. The system developed as a result series episodes Caledonian orogeny early Tertiary Palaeozoic rifting is poorly...

[1] Seismic reflection and refraction profiles, potential field data, complemented by crustal-scale gravity modeling plate reconstructions are used to study the evolution of central south segments South Atlantic conjugate margins. The segment is characterized a hyperextended continent-ocean transitional domain that shows evidence rotated fault blocks detachment surface active during rifting. A polyphase rifting mode, associated with complex time-dependent thermal structure lithosphere,...
Abstract The opening of the Arctic oceanic basins in Mesozoic and Cenozoic proceeded steps, with episodes magmatism sedimentation marking specific stages this development. In addition to stratigraphic record provided by sediments fossils, intrusive extrusive rocks yield important information on evolution.

Abstract The northern North Sea rift basin developed on a heterogeneous crust comprising structures inherited from the Caledonian orogeny and Devonian postorogenic extension. Integrating two‐dimensional regional seismic reflection data information basement wells, we investigate prerift structural configuration in rift. Three facies have been defined below base surface: (1) relatively low‐amplitude low‐frequency reflections, interpreted as pre‐Caledonian metasediments, nappes, and/or clastic...
Mafic igneous rocks of Cretaceous age (80–130 Ma) scattered around the Arctic Ocean are commonly referred to as High Large Igneous Province (HALIP). We have mapped out distribution HALIP in Barents Sea region over past decade based on integrated seismic–gravity–magnetic interpretation, field work, review publications, and analyses new vintage borehole samples. The mapping reveals abundant northern eastern covering an area ~ 900,000 km2 with a conservative volume estimate 100,000 200,000 km3...
Abstract The northern North Sea rift evolved through multiple phases within a highly heterogeneous crystalline basement. geometry and evolution of syn‐rift depocenters during this multiphase the mechanisms extent to which they were influenced by preexisting structural heterogeneities remain elusive, particularly at regional scale. Using an extensive database borehole‐constrained 2D seismic reflection data, we examine how physiography throughout late Permian‐Early Triassic (RP1) Late...
Abstract The northern North Sea region has experienced repeated phases of post-Caledonian extension, starting with extensional reactivation the low-angle basal Caledonian thrust zone, then formation Devonian shear zones 10–100 km-scale displacements, followed by brittle and creation a plethora faults. Rift-related approximately east–west extension created new set rift-parallel faults that cut across less favourably orientated pre-rift structures. Nevertheless, fault rock dating shows onshore...
Abstract On the Vøring Margin offshore mid‐Norway, Paleogene continental breakup was characterized by extrusion of large volumes flood basalts erupted in different depositional environments. The transition from subaerial to submarine emplacement environment is marked formation Escarpment which records early encroachment basalt into basin and buildup a lava delta system. increased availability new reprocessed high‐quality seismic data allows more detailed characterization along‐strike...
Abstract The Palaeocene–Eocene Thermal Maximum (PETM) was a global warming event of 5–6 °C around 56 million years ago caused by input carbon into the ocean and atmosphere. Hydrothermal venting greenhouse gases produced in contact aureoles surrounding magmatic intrusions North Atlantic Igneous Province have been proposed to play key role PETM carbon-cycle perturbation, but precise timing, magnitude climatic impact such remains uncertain. Here we present seismic data results five-borehole...
In the Jurassic–Cretaceous North Sea basin, synrift sequence is separated from post-rift by ‘base Cretaceous’ or ‘late Cimmerian’ unconformity. The unconformity covers almost entire has a distinct character in seismic reflection data and wireline logs, hence, easily identified correlated, making it most important marker horizon area. displays great local complexity (in many localities) variability on regional scale (from one locality to another). Thus classified as nonconformity,...
