Basement structure and its influence on the structural configuration of the northern North Sea rift
(Peer reviewed; Journal article, 2017-06)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 ... -
Complex strain partitioning and heterogeneous extension rates during early rifting in the East Shetland Basin, northern North Sea
(Journal article; Peer reviewed, 2020)The early stages of continental rifting are accommodated by the growth of upper crustal normal fault systems that are distributed relatively evenly across the rift width. Numerous fault systems define fault arrays, the ... -
Deep Crustal Flow Within Postorogenic Metamorphic Core Complexes: Insights From the Southern Western Gneiss Region of Norway
(Peer reviewed; Journal article, 2019)Viscous crustal flow can exhume once deeply buried rocks in postorogenic metamorphic core complexes (MCCs). While migmatite domes record the flow dynamics of anatectic crust, the mechanics and kinematics of solid‐state ... -
Evaluating balanced section restoration with thermochronology data: A case study from the Central Pyrenees
(Peer reviewed; Journal article, 2014-05-06)We present a new method that can be used to quantitatively evaluate the consistency between balanced section restorations and thermochronological data sets from orogenic belts. We have applied our method to a crustal-scale ... -
From Caledonian collapse to North Sea Rift: The extended history of a metamorphic core complex
(Journal article; Peer reviewed, 2020)Extensional systems evolve through different stages due to changes in the rheological state of the lithosphere. It is crucial to distinguish ductile structures formed before and during rifting, as both cases have important ... -
The Impact of Pre‐Salt Rift Topography on Salt Tectonics: A Discrete‐Element Modeling Approach
(Peer reviewed; Journal article, 2019)Gravity‐driven salt tectonics along passive margins is commonly depicted as comprising domains of updip extension and downdip contraction linked by an intermediate, broadly undeformed zone of translation. This study expands ... -
The influence of structural inheritance and multiphase extension on rift development, the northern North Sea
(Peer reviewed; Journal article, 2019-11-08)The northern North Sea rift evolved through multiple rift phases within a highly heterogeneous crystalline basement. The geometry and evolution of syn‐rift depocenters during this multiphase evolution and the mechanisms ... -
Influence of Zones of Pre-Existing Crustal Weakness on Strain Localization and Partitioning During Rifting: Insights From Analog Modeling Using High-Resolution 3D Digital Image Correlation
(Journal article; Peer reviewed, 2021)Pre-existing crustal structures are known to influence rifting, but the factors controlling their influence remain poorly understood. We present results of digital image correlation that allows for the surface strain ... -
Mesozoic-Cenozoic regional stress field evolution in Svalbard
(Journal article; Peer reviewed, 2020)Cooling fracture orientations in diabase sills associated with the Cretaceous High Arctic Large Igneous Province and syn‐sedimentary Triassic faults help constrain a model for Svalbard's (NE Barents Shelf) Mesozoic stress ... -
Normal Fault Kinematics and the Role of Lateral Tip Retreat: An Example From Offshore NW Australia
(Journal article; Peer reviewed, 2021)Understanding how normal faults grow is key to determining the tectono-stratigraphic evolution of rifts. According to recent studies, normal faults tend to grow in two temporally distinct stages: a lengthening stage, ... -
The Role of Subduction Interface and Upper Plate Strength on Back-Arc Extension: Application to Mediterranean Back-Arc Basins
(Journal article; Peer reviewed, 2021)While there has been a lot of work focusing on improving our understanding of divergent and convergent plate boundaries, the intricate nature of back-arc extension, where subduction and large-scale extension occur and ... -
Structural inheritance and rapid rift-length establishment in a multiphase rift: The East Greenland rift system and its Caledonian orogenic ancestry
(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 ... -
Zippered Shear Zone Model for Interacting Shear Zones in the Borborema Province, Brazil, as Constrained by U-Pb Dating
(Peer reviewed; Journal article, 2019)Shear zones typically interact to form connected systems or networks to accommodate crustal deformation, but our knowledge of how this happens is fragmentary. Understanding branching and interacting shear zones requires ...
