Pichel, Leonardo Muniz; Huismans, Ritske Sipke; Gawthorpe, Rob; Faleide, Jan Inge; Theunissen, Thomas Louis Roger Dominique (Journal article; Peer reviewed, 2022)Rifted margins are often associated with widespread and thick evaporite (salt) deposits and pronounced salt tectonics.

Wolf, Lorenz; Huismans, Ritske Sipke; Rouby, Delphine; Gawthorpe, Rob; Wolf, Sebastian Georg (Journal article; Peer reviewed, 2022)Continental rifts form by extension, and their subsequent evolution depends on the tectonic and climatic boundary conditions. We investigate how faulting, topography, and the evolution of the sediment flux during rifting ... -

Ge, Zhiyuan; Gawthorpe, Rob; Rotevatn, Atle; Zijerveld, Leo; Jackson, Christopher; Oluboyo, Ayodeji P. (Peer reviewed; Journal article, 2019)Salt tectonics is an important part of the geological evolution of many continental margins, yet the four‐dimensional evolution of the minibasins, the fundamental building block of these and many other salt basins, remains ... -
A new deglacial climate and sea-level record from 20 to 8 ka from IODP381 site M0080, Alkyonides Gulf, eastern Mediterranean
Mazzini, Ilaria; Cronin, Thomas M.; Gawthorpe, Rob; Ll Collier, Richard E.; de Gelder, Gino; Golub, Anna Rose; Toomey, Michael R.; Poirier, Robert K.; May Huang, Huai-Hsuan; Phillips, Marcie Purkey; McNeill, Lisa C.; Shillington, Donna J. (Journal article; Peer reviewed, 2023)Records of relative sea-level rise for the last deglaciation are mostly limited to coral reef records and geophysical model estimates, but observational data from regions with temperate climates is sparse. We present a new ... -
Overprinting translational domains in passive margin salt basins: insights from analogue modelling
Ge, Zhiyuan; Rosenau, Matthias; Warsitzka, Michael; Gawthorpe, Rob (Peer reviewed; Journal article, 2019-08-02)Current models of gravitational tectonics on the structural styles of salt-influenced passive margins typically depict domains of upslope extension and corresponding downslope contraction separated by a mid-slope domain ... -
Pre-existing intra-basement shear zones on the development of non-colinear rift fault network, Utsira High – Heimdal Terrace, North Sea
Osagiede, Edoseghe Edwin; Rotevatn, Atle; Gawthorpe, Rob; Kristensen, Thomas Berg; Jackson, Christopher; Marsh, Nicola (Peer reviewed; Journal article, 2020)Pre-existing intra-basement shear zones can induce mechanical and rheological heterogeneities that may influence rifting and the overall geometry of rift-related normal faults. However, the extent to which physical and ... -
Progressive tilting of salt-bearing continental margins controls thin-skinned deformation
Ge, Zhiyuan; Rosenau, Matthias; Warsitzka, Michael; Gawthorpe, Rob (Peer reviewed; Journal article, 2019)As a primary driving force, margin tilting is crucial for gravity-driven thin-skinned salt tectonics. We investigated how instant versus progressive margin tilting mechanisms influence salt tectonics using an analogue ... -
Rift kinematics preserved in deep-time erosional landscape below the northern North Sea
Wrona, Thilo; Whittaker, Alexander C.; Bell, Rebecca E.; Gawthorpe, Rob; Fossen, Haakon; Jackson, Christopher A.-L.; Bauck, Marit Stokke (Journal article; Peer reviewed, 2022)Our understanding of continental rifting is, in large parts, derived from the stratigraphic record. This record is, however, incomplete as it does not often capture the geomorphic and erosional signal of rifting. New 3D ... -
The role of structural inheritance in the development of high-displacement crustal faults in the necking domain of rifted margins: The Klakk Fault Complex, Frøya High, offshore mid-Norway
Munoz Barrera, Jhon Meyer; Rotevatn, Atle; Gawthorpe, Rob; Henstra, Gijs Allard; Kristensen, Thomas Berg (Journal article; Peer reviewed, 2020-08-20)The role of inherited structures during the development of normal faults in continental rifts and proximal domains of passive margins have been extensively studied.
