3D geometry and displacement transfer of an oblique relay zone on outcropping normal faults Open
Relay zones on normal faults accommodate transfer of displacement between adjacent segments. We study vertical and horizontal displacement transfer mechanisms across a relay zone adjacent to the Moab Fault at Courthouse Rock (Utah, USA). T…

Impact of Variable Fault Geometries and Slip Rates on Earthquake Catalogs From Physics‐Based Simulations of a Normal Fault Open
Physics‐based earthquake simulators have been developed to overcome the relatively short duration and incompleteness of historical earthquake and paleoseismic records, respectively. These simulators have the potential to be a useful additi…

Bed-parallel slip associated with normal fault systems Open
Stretching of the Earth's upper crust is commonly accommodated by normal faulting, fault-related folding and/or fracturing such as veins and joints. However, an increasing number of outcrop-scale studies highlight that extension is also ac…

3‐D Structure and Development of a Metamorphic Core Complex in the Northern South China Sea Rifted Margin Open
The 3‐D structure of continental metamorphic core complexes (MCCs) and their coevolution along with the associated extensional detachments are still not well understood. In this study, analysis of a newly acquired high‐resolution 3‐D seism…

Geometrical characterisation of fault arrays in three dimensions Open
<p>Normal faults are often complex three-dimensional structures comprising multiple sub-parallel segments separated by intact or breached relay zones. In this study we outline geometrical characterisations capturing this 3D complexit…

Multiphase deformation history of the Porcupine Basin, offshore west Ireland Open
The Porcupine Basin is a large underexplored sedimentary basin located offshore west of Ireland within the structurally complex European North Atlantic Margin. The basin has evolved through multiple Jurassic–Recent phases of deformation an…
View article: Throw variations and strain partitioning associated with fault-bend folding along normal faults
Throw variations and strain partitioning associated with fault-bend folding along normal faults Open
Normal faults have irregular geometries on a range of scales arising from different processes including refraction and segmentation. A fault with constant dip and displacement on a large-scale will have irregular geometries on smaller scal…

Three-dimensional geometries of relay zones in normal faults Open
<p>Individual normal faults are rarely single planar surfaces and often comprise arrays of fault segments arising from the earliest stages of fault propagation. Current models for the geometry and formation of relay zones between adj…

The three-dimensional geometries of segmented normal faults Open
<p>Normal faults are often complex three dimensional structures comprising multiple sub-parallel segments separated by intervening relay zones. In this study we outline geometrical characterisations capturing this 3D complexity and p…

Changes in the location of the nucleation point of slip events on ancient normal faults Open
<p>The lack of an unambiguous method for determining the propagation direction of slip events on faults over significant time periods limits our understanding of the long-term stability of fault slip propagation directions. A geologi…

Throw variations and strain partitioning associated with fault-bend folding along normal faults Open
Normal faults have irregular geometries on a range of scales arising from different processes including refraction and segmentation. A fault with an average dip and constant displacement on a large-scale, will have irregular geometries on …

3D fault zone architecture in Kardia Mine, Ptolemais Basin, Greece Open
Research on normal faults derives mainly from outcrop- and seismic-based studies. Outcrops are characterized by their high resolution but often lack a 3D context, in contrast with seismic-based data that can be fully 3D but with limited re…

Throw partitioning across normal fault zones in the Ptolemais Basin, Greece Open
The total throw across a fault zone may not occur entirely on a single fault strand but may be distributed onto several strands or may be accommodated by distributed deformation within or adjacent to the fault zone. Here we conduct a quant…
