The brittle evolution of Western Norway – A space-time model based on fault mineralizations, K–Ar fault gouge dating and paleostress analysis
(Journal article; Peer reviewed, 2022)Basement fracture and fault patterns on passive continental margins control the onshore landscape and offshore distribution of sediment packages and fluid pathways. In this study, we decipher the spatial-temporal evolution ... -
Contractional deformation of porous sandstone: Insights from the Aztec Sandstone, SE Nevada, USA
(Peer reviewed; Journal article, 2015-05)Contractional deformation of highly porous sandstones is poorly explored, as compared to extensional deformation of such sedimentary rocks. In this work we explore the highly porous Aztec Sandstone in the footwall to the ... -
Evolution of a major segmented normal fault during multiphase rifting: The origin of plan-view zigzag geometry
(Peer reviewed; Journal article, 2015-05)This case study addresses fault reactivation and linkage between distinct extensional episodes with variable stretching direction. Using 2-D and 3-D seismic reflection data we demonstrate how the Vesterdjupet Fault Zone, ... -
Microstructure and fluid flow in the vicinity of basin bounding faults in rifts – The Dombjerg Fault, NE Greenland rift system
(Journal article; Peer reviewed, 2021)Faults commonly form loci for high fluid flux in sedimentary basins, where fluids, rocks and deformation processes frequently interact. Here, we elucidate the interaction of fluid flow, diagenesis and deformation near ... -
Outcrop-scale fracture analysis and seismic modelling of a basin-bounding normal fault in platform carbonates, central Italy
(Journal article; Peer reviewed, 2022)Faults are characterized by a complex internal architecture. In carbonates, the geometry, attitude, and distribution of fault-related fractures and subsidiary faults can largely affect the petrophysical properties and hy ... -
The Patos-Pernambuco shear system of NE Brazil: Partitioned intracontinental transcurrent deformation revealed by enhanced aeromagnetic data
(Journal article; Peer reviewed, 2022)The Neoproterozoic-Cambrian (Brasiliano) intracontinental Patos-Pernambuco shear system is developed in Archean to Neoproterozoic crust, reactivating rift margins N of the São Francisco Craton. We here use enhanced ... -
Pre-existing intra-basement shear zones on the development of non-colinear rift fault network, Utsira High – Heimdal Terrace, North Sea
(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 ... -
Quantifying structural controls on fluid flow: Insights from carbonate-hosted fault damage zones on the Maltese Islands
(Peer reviewed; Journal article, 2017-08)Structural complexity along faults (e.g., relay zones, fault intersections and jogs) exert strong controls on fluid flow, yet few attempts have been made to quantify and visualise such relationships. This paper does that ... -
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
(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. Few studies, however, have a focus on deciphering the ... -
Seismic expression of shear zones: Insights from 2-D point-spread-function based convolution modelling
(Journal article; Peer reviewed, 2020)Shear zones are common strain localization structures in the middle and lower crust and play a major role during orogeny, transcurrent movements and rifting alike. Our understanding of crustal deformation depends on our ... -
Shear zone evolution during core complex exhumation – Implications for continental detachments
(Journal article; Peer reviewed, 2020)The formation of low-angle detachments involves exhumation of previously ductile material and fault zone weakening. To better understand this relationship, we studied a deeply eroded metamorphic core complex, which formed ... -
Spatial variability in topology, connectivity and permeability of deformation band networks: Insights from the Jurassic Entrada Sandstone, Utah
(Journal article; Peer reviewed, 2023)Networks of deformation bands have the potential to act as baffles to fluid flow, yet little work has been devoted to addressing their network properties, such as topology and connectivity. Motivated by this, we investigate ... -
West Spitsbergen fold and thrust belt: A digital educational data package for teaching structural geology
(Journal article; Peer reviewed, 2023)The discipline of structural geology is taking an advantage of compiling observations from multiple field sites to comprehend the bigger picture and constrain the region's geological evolution. In this study we demonstrate ...
