Experimental investigation on the pore structure and Water Inrush Evolution Law of weakly cemented fault fracture zone with different filling gradations

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources, 2023
Water and mud inrush caused by fault is a geological disaster characterized by high frequency and huge destructiveness. It is important to study the evolutionary laws of water inrush in fault fracture zones with various filling types.

Interpretation of Magnetic Anomalies over 2D Fault and Sheet-Type Mineralized Structures Using Very Fast Simulated Annealing Global Optimization: An Understanding of Uncertainty and Geological Implications

open access: yesLithosphere, 2021
Identification of intraterrane dislocation zones and associated mineralized bodies is of immense importance in exploration geophysics. Understanding such structures from geophysical anomalies is challenging and cumbersome.

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

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.

Part I. Slip Behavior of the San Andreas Fault Through Several Earthquake Cycles Part II. A Structural Interpretation of the Aftershock "Cloud" of the 1992 Mw 7.3 Landers Earthquake [PDF]

open access: yes, 2003
Part 1 of this thesis addresses the question of how variable fault slip per event is through time. This question is important, because progress in understanding and forecasting large earthquakes depends critically on precise reconstruction of the ...

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.

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

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 ...

Experimental Insights Into Fault Reactivation in Gouge‐Filled Fault Zones [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2019
AbstractFaults in the brittle crust constitute preexisting weakness zones that can be reactivated depending on their friction, orientation within the local stress field, and stress field magnitude. Analytical approaches to evaluate the potential for fault reactivation are generally based on the assumption that faults are ideal planes characterized by ...

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.
