[HTML][HTML] Structural inheritance in amagmatic rift basins: Manifestations and mechanisms for how pre-existing structures influence rift-related faults

A Samsu, S Micklethwaite, JN Williams… - Earth-Science …, 2023 - Elsevier
In the context of rift basin formation, structural inheritance describes the influence of pre-
existing structures on new rift-related structures, including faults. Pre-existing structures in …

The Malawi active fault database: An onshore‐offshore database for regional assessment of seismic hazard and tectonic evolution

JN Williams, LNJ Wedmore, CA Scholz… - Geochemistry …, 2022 - Wiley Online Library
Abstract We present the Malawi Active Fault Database (MAFD), an open‐access (https://doi.

Under-displaced normal faults: Strain accommodation along an early-stage rift-bounding fault in the Southern Malawi Rift

OO Ojo, LO Ohenhen, F Kolawole… - Frontiers in Earth …, 2022 - frontiersin.org
One of the fundamental problems in continental rift segmentation and propagation is how
strain is accommodated along large rift-bounding faults (border faults) since the …

The deep basin and underlying basement structure of the Tanganyika Rift

SN Shaban, F Kolawole, CA Scholz - Tectonics, 2023 - Wiley Online Library
The oldest structures in a rift basin define incipient rift architecture, and commonly modulate
the patterns of landscape evolution, sedimentation, and associated hazards in subsequent …

Detrital zircon and apatite U-Pb provenance and drainage evolution of the Newark Basin during progressive rifting and continental breakup along the Eastern North …

ZS Foster-Baril, DF Stockli - Geosphere, 2023 - pubs.geoscienceworld.org

United States to the Grand Banks of Canada and formed during progressive extension prior …

[HTML][HTML] Comparing intrarift and border fault structure in the Malawi Rift: Implications for normal fault growth

M Carpenter, JN Williams, Å Fagereng… - Journal of Structural …, 2022 - Elsevier
Early stages of normal fault growth are seldom described using field observations of active
normal faults. Here we first estimate the displacements of active border and intrarift faults in …

Knickpoint morphotectonics of the Middle Shire River basin: Implications for the evolution of rift interaction zones

Z Dulanya, SF Gallen, F Kolawole, JN Williams… - Basin …, 2022 - earthdoc.org
Tectonic and paleo‐environmental reconstructions of rift evolution typically rely on the
interpretation of sedimentary sequences, but this is rarely possible in early‐stage rifts where …

Strain localization and migration during the pulsed lateral propagation of the Shire Rift Zone, East Africa

F Kolawole, T Vick, EA Atekwana, DA Laó-Dávila… - Tectonophysics, 2022 - Elsevier
We investigate the spatiotemporal patterns of strain accommodation during multiphase rift
evolution in the Shire Rift Zone (SRZ), East Africa. The NW-trending SRZ records a transition …

Fault-based probabilistic seismic hazard analysis in regions with low strain rates and a thick seismogenic layer: a case study from Malawi

JN Williams, MJ Werner, K Goda… - Geophysical Journal …, 2023 - academic.oup.com
Historical and instrumental earthquake catalogs in low strain rate regions are not
necessarily indicative of the long-term spatio-temporal distribution of seismicity. This implies …
