Fault zone architecture and its scaling laws: where does the damage zone start and stop?

open access: yesSpecial Publications, 2019
Damage zones of different fault types are investigated in siliciclastics (Utah, USA), carbonates (Majella Mountain, Italy) and metamorphic rocks (western Norway).

The strong activities of the Namula fault zone in the eastern Himalayan syntaxis since Pliocene, constraints from thermochronological data

open access: yesDizhi lixue xuebao, 2021
To reveal the strong activities of the Namula fault zone in the eastern Himalayan syntaxis since Pliocene, this paper reports biotite 40Ar/39Ar and apatite fission track ages of 3 rock samples from the Namula fault zone, and quantitatively interpret ...

Seismicity relocation and fault structure near the Leech River Fault Zone, southern Vancouver Island [PDF]

open access: yes, 2018
Relatively low rates of seismicity and fault loading have made it challenging to correlate microseismicity to mapped surface faults on the forearc of southern Vancouver Island.

Identification and evaluation of fault-fracture reservoirs in buried hills of the Lower Paleozoic, Chengdao area, China

open access: yesEnergy Geoscience, 2023
The Bohai Bay Basin is a Meso-Cenozoic rifted basin where the Paleozoic buried hills with great hydrocarbon potentials are well developed. The reservoir space types are complex and diverse due to tectonic activities, making fracture distribution highly ...

Fault weakening across the frictional‐viscous transition zone, Karakoram Fault Zone, NW Himalaya [PDF]

open access: yesTectonics, 2013
AbstractExhumed fault rocks formed in the frictional‐viscous transition zone (FVTZ) provide test material that can be used to assess the strength of natural fault zones. In the Karakoram Fault Zone (KFZ), such rocks contain evidence of several long‐term weakening mechanisms associated with reduced coefficients of friction (<0.4). The Nubra, Tangtse,

Simulating spatial and temporal evolution of multiple wing cracks around faults in crystalline basement rocks [PDF]

open access: yes, 2007
Fault zones are structurally highly spatially heterogeneous and hence extremely complex. Observations of fluid flow through fault zones over several scales show that this structural complexity is reflected in the hydrogeological properties of faults ...

Research on the quantitative method of fault sealing to coal seam gas

open access: yesMeitan kexue jishu, 2023
Fault has the dual function of sealing and channel to coal seam gas, which mainly depends on the sealing ability of the fault. Aiming at the quantitative characterization method of fault sealing ability to gas, combined with the multi-element theory of ...

Spectral-element simulations of long-term fault slip: Effect of low-rigidity layers on earthquake-cycle dynamics [PDF]

open access: yes, 2011
We develop a spectral element method for the simulation of long-term histories of spontaneous seismic and aseismic slip on faults subjected to tectonic loading.

Characterization of Fault Zones [PDF]

open access: yesPure and Applied Geophysics, 2003
There are currently three major competing views on the essential geometrical, mechanical, and mathematical nature of faults. The standard view is that faults are (possibly segmented and heterogeneous) Euclidean zones in a continuum solid. The continuum-Euclidean view is supported by seismic, gravity, and electromagnetic imaging studies; by successful ...
