Constitutive properties of clayey fault gouge from the Hanaore fault zone, southwest Japan
[1] Velocity step tests at a range of slip rates (0.0154–155.54 mm s ) are performed using natural fault gouge containing smectite, mica, and quartz collected from an outcrop of the Hanaore Fault, southwest Japan. Field and microscopic observations reveal that the shear deformation is localized to a few centimeters or thinner layer of black clayey fault gouge. This layer is formed by multiple s...
متن کاملFrictional and hydrologic properties of clay-rich fault gouge
[1] The slip behavior of major faults depends largely on the frictional and hydrologic properties of fault gouge. We report on laboratory experiments designed to measure the strength, friction constitutive properties, and permeability of a suite of saturated clay-rich fault gouges, including: a 50:50% mixture of montmorillonite-quartz, powdered illite shale, and powdered chlorite schist. Fricti...
متن کاملSatellite thermal surveys to detecting hidden active faults and fault termination, Case study of Quchan fault, NE Iran
The Quchan fault is located in Quchan - Shirvan area which is a part of Chenaran- Bojnourd plain in Kopeh-Dagh zone, NE Iran. The Quchan active fault with northwest – southeast trending is one of the most important strike-slip faults in the area which its activity led to the numerous historical and instrumental earthquakes. The Neo-tectonic activities of this fault are investigated by the drain...
متن کاملEffect of hydration state on the frictional properties of montmorillonite-based fault gouge
[1] We report on laboratory experiments examining the effect of hydration state on the frictional properties of simulated clay and quartz fault gouge. We tested four mixtures of Ca-montmorillonite and quartz (100, 70, 50, and 30% montmorillonite) at four hydration states: dry (<4.50 wt% water), one water interlayer equivalent (4.5–8.7 wt% water), two layers (8.7–16.0 wt% water), and three layer...
متن کاملStudy on Fault Current of DFIG during Slight Fault Condition
In order to ensure the safety of DFIG when severe fault happens, crowbar protection is adopted. But during slight fault condition, the crowbar protection will not trip, and the DFIG is still excited by AC-DCAC converter. In this condition, operation characteristics of the converter have large influence on the fault current characteristics of DFIG. By theoretical analysis and digital simulation,...
