Impacts of seismic resolution on fault interpretation: Insights from seismic modelling
Faleide, Thea Sveva; Braathen, Alvar; Lecomte, Isabelle Christine; Mulrooney, Mark Joseph; Midtkandal, Ivar; Bugge, Aina J.; Planke, Sverre (Journal article; Peer reviewed, 2021)Seismic mapping of subsurface faults is hampered by factors such as seismic resolution, velocity control for depth conversion and human bias. Here, we explore the challenges and pitfalls related to interpreting normal ... -
A new high-resolution stratigraphic and palaeoenvironmental record spanning the End-Permian Mass Extinction and its aftermath in central Spitsbergen, Svalbard
Zuchuat, Valentin; Sleveland, Arve; Twitchett, Richard; Svensen, Henrik; Turner, Holly E; Augland, Lars Eivind; Jones, Morgan Thomas; Hammer, Øyvind; Hauksson, Bjarki; Haflidason, Haflidi; Midtkandal, Ivar; Planke, Sverre (Journal article; Peer reviewed, 2020-09-15)Research on the Permian-Triassic boundary (PTB) along the northern margins of Pangaea (exposed today in the Arctic region) has been heavily reliant on field observations, where data resolution was consequently determined ... -
Rapid and sustained environmental responses to global warming: the Paleocene–Eocene Thermal Maximum in the eastern North Sea
Stokke, Ella W.; Jones, Morgan Thomas; Riber, Lars; Haflidason, Haflidi; Midtkandal, Ivar; Schultz, Bo; Svensen, Henrik (Journal article; Peer reviewed, 2021)The Paleocene–Eocene Thermal Maximum (PETM; ∼ 55.9 Ma) was a period of rapid and sustained global warming associated with significant carbon emissions. It coincided with the North Atlantic opening and emplacement of the ... -
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 ...
