DOI: 10.1007/s40948-016-0047-x
Abstract: We present a field-study based workflow to develop 3D-numerical models on local stress fields within fault zones hosted in layered rocks at reservoir depths. As an example we use the carbonate successions of the Upper… read more here.

The highest potential transmissivities of fractures in fault zones: Reference values based on laboratory and in situ hydro-mechanical experimental data
Sign Up to like & getrecommendations! Published in 2021 at "Engineering Geology"
DOI: 10.1016/j.enggeo.2021.106369
Abstract: Abstract The transmissivity of a fracture can be related to fracture roughness (JRC0), initial aperture (E0), effective normal stress (σ'n), and tensile strength (σt) of the intact rock, based on the Barton–Bandis model and their… read more here.

Repeated reactivation of the Gavilgarh-Tan Shear Zone, Central India: Implications for the tectonic survival of deep-seated intra-continental fault zones

DOI: 10.1016/j.jseaes.2019.104051
Abstract: Abstract Continental crust accommodates crustal deformation through repeated reactivation of old shear/fault zones that constitute domains of long-term structural weakness. Reactivation is often triggered by mechanical and chemical (fluid-assisted) changes of the host rocks within… read more here.

Faulting Processes Unveiled by Magnetic Properties of Fault Rocks
Sign Up to like & getrecommendations! Published in 2020 at "Reviews of Geophysics"
DOI: 10.1029/2019rg000690
Abstract: As iron‐bearing minerals—ferrimagnetic minerals in particular—are sensitive to stress, temperature, and presence of fluids in fault zones, their magnetic properties provide valuable insights into physical and chemical processes affecting fault rocks. Here, we review the… read more here.

DOI: 10.1306/12181817393
Abstract: Some fault zones leak vertically to the ground surface or seafloor, whereas most others remain naturally sealed. Understanding the factors that cause this leakage is essential for predicting and preventing such leakage for both conventional… read more here.
