The geometry and thickness of deformation-band fault core and its influence on sealing characteristics of deformation-band fault zones [PDF]

open access: yes, 2005
Deformation-band faults in high-porosity reservoir sandstones commonly contain a fault core of intensely crushed rock surrounding the main slip surfaces.

The structure and composition of exhumed faults, and their implications for seismic processes [PDF]

open access: yes, 2000
Field studies of faults exhumed from seismogenic depths provide useful data to constrain seismologic models of fault zone processes and properties. Data collected on the San Andreas Fault in the San Gabriel Mountains has shown that large-displacement ...

Scale-dependent influence of pre-existing basement shear zones on rift faulting : a case study from NE Brazil [PDF]

open access: yes, 2013
Rifting of continental crust initiates faults that are commonly influenced by pre-existing structures. We document newly identified faults cutting Precambrian units in the interior of the NE Brazilian margin to assess the effects of structural ...

Strike-slip fault terminations at seismogenic depths : the structure and kinematics of the Glacier Lakes fault, Sierra Nevada United States [PDF]

open access: yes, 2008
Structural complexity is common at the terminations of earthquake surface ruptures; similar deformation may therefore be expected at the end zones of earthquake ruptures at depth.

Directional Amplification at Rock Sites in Fault Damage Zones

open access: yesApplied Sciences, 2023
Site effects refer to the modification of ground shaking caused by the local geological conditions that can result in the strong amplification of ground motion.

Indicators of active faults on the example of Gomel Structural Bridge

open access: yesИзвестия высших учебных заведений: Геология и разведка
Introduction. Modern geodynamic activity manifests itself in fault zones of aseismic regions as fluctuations in the fluid-gas regime, which determines the importance of gas geochemical indicators.Aim.

Integration of the GPR and radio-impedance techniques in studies of the Baikal rift zone

open access: yesГеодинамика и тектонофизика, 2019
Radiowave propagation techniqueshave been very rarely applied to investigate tectonic fault zones and geoelectric profilesof the Baikal rift zone. In our study, we used a combination ofground-penetrating radar (GPR) and radioimpedance techniquesin order ...

Preliminary study on the Late Quaternary activity of important active fault zones along the Yunnan-Tibet railway

open access: yes地震科学进展
The Yunnan-Tibet railway is located in the southeastern edge of the Tibetan Plateau, where tectonic plates collide and the terrain rapidly changes. Along the line, active faults develops, earthquakes occur frequently, and the intensity of earthquakes is ...
