Beyond Byerlee friction, weak faults and implications for slip behavior

C Collettini, T Tesei, MM Scuderi, BM Carpenter… - Earth and Planetary …, 2019 - Elsevier
Some faults are considered strong because their strength is consistent with the Coulomb
criterion under Byerlee's friction, 0.6< μ< 0.85. In marked contrast, numerous studies have …

Recent advances in characterizing the crustal stress field and future applications of stress data: Perspectives from North America

JE Lundstern - Geological Society, London, Special Publications, 2024 - lyellcollection.org
The stress field controls patterns of crustal deformation, including which faults are likeliest to
cause earthquakes or transmit fluids. Since the 1950s, maps of maximum horizontal stress …

Constitutive behavior of rocks during the seismic cycle

S Barbot - AGU Advances, 2023 - Wiley Online Library
Establishing a constitutive law for fault friction is a crucial objective of earthquake science.

Fault failure modes, deformation mechanisms, dilation tendency, slip tendency, and conduits v. seals

DA Ferrill, KJ Smart, AP Morris - Geological Society, London …, 2020 - lyellcollection.org
Faults have complicated shapes. Non-planarity of faults can be caused by variations in
failure modes, which in turn are dictated by mechanical stratigraphy interacting with the …

Repeated brittle reactivations of a pre-existing plastic shear zone: combined K–Ar and 40Ar–39Ar geochronology of the long-lived (> 700 Ma) Himdalen–Ørje …
