Structural patterns of fault damage zones in carbonate rocks and their influences on petroleum accumulation in Tazhong Paleo-uplift, Tarim Basin, NW China

open access: yesPetroleum Exploration and Development, 2018
Based on the outcrop survey, 3D seismic data interpretation, drilling data analysis, the structural patterns and distribution of fault damage zones in carbonate strata of Tazhong Paleo-uplift were established to reveal the oil and gas enrichment law in ...

Interaction of piled foundation with a rupturing normal fault [PDF]

open access: yes, 2013
Post-seismic observations in the 1999 Kocaeli earthquake in Turkey have indicated that piled foundations may be less suitable than stiff mat foundations in defending a structure against a major normal fault rupturing underneath.

Constraints on upper crustal fluid circulation and seismogenesis from in-situ outcrop quantification of complex fault zone permeability

open access: yesScientific Reports, 2023
The permeability of fault zones plays a significant role on the distribution of georesources and on seismogenesis in the brittle upper crust, where both natural and induced seismicity are often associated with fluid migration and overpressure.

Shallow Composition and Structure of the Upper Part of the Exhumed San Gabriel Fault, California: Implications for Fault Processes

open access: yesTektonika, 2023
Quantifying shallow fault zone structure and characteristics is critical for accurately modeling the complex mechanical behavior of earthquakes as energy moves within faults from depth.

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 ...

Experimental investigation on the rheology of fault rocks [PDF]

open access: yes, 2014
The aim of this study is to explore and identify physical and chemical processes occurring during deformation of fault rocks under elevated pressures and temperatures where an interplay between brittle/frictional and viscous processes is expected.

Factors controlling the thickness of fault damage zones in carbonates (Central Apennines, Italy) [PDF]

open access: yes, 2022
The Italian Central Apennines are one of the most seismically active areas in the Mediterranean (e.g., L’Aquila-Pizzoli Mw 6.7, 1703; Avezzano Mw 7.1, 1915; L’Aquila Mw 6.1, 2009).
