[1] The effect of off-fault damage on the speed of ruptures propagating on faults in photoelastic Homalite plates was measured using high-speed digital photography. The offfault damage was composed of a network of fractures introduced by thermally shocking the Homalite in liquid nitrogen. The mode II rupture speed measured in damaged Homalite was significantly lower than the limiting Rayleigh s...

the doruneh fault is one of the longest and most prominent faults in iran. however, only two recorded historical earthquakes with magnitudes more than 7 might be related to this fault. for getting more information on this fault more investigation in different fields are required. fault displacement is one of the most important parameters needed to explore the fault activity. in this study, with...

Studying hydrothermal systems in basement environments requires knowledge of fault and fracture network distributions. This study addresses this through multi-scale structural analysis the Têt its surrounding (Eastern Pyrénées) using remote sensing field data. aims to achieve through: 1) precisely mapping describing brittle network, 2) analysing distribution lineaments outcrop-scale fractures r...

the sofeh mountain in the south of isfahan (iran) has a development of shafts (vertical cave). simorgh cave with a depth of 42 m and a length of 52 m has developed along significant fault structures. structural analysis indicates relationships of orientation between the faults and fractures and shafts and chambers geometries. considering the main ne-sw trend of tectonic structures in the area, ...

The Tullacondra Cu-Ag deposit is located on the southern margin of Lower Carboniferous Irish Midlands orefield and contains historical reserves approximately 4.2 Mt at 0.7% Cu 27.5 ppm Ag. hosted within hanging wall a feeder fault, EW-trending Fault, where sulfides sulfosalts containing elevated Cu, Ag, As, Sb deposited, whereas Zn Pb are nearly absent. deposition in took place along bedding be...

Understanding the impact of fault zones on reservoir trap properties is a major challenge for variety geological resources applications. Fault in cohesive rocks are complex structures, composed 3 components: rock matrix, damage zone fractures and core rock. Despite diversity methods to estimate permeability/drain properties, up date none them integrate simultaneously all three components, nor t...

In recent years, the Ordovician fault-controlled fracture-cavity reservoirs developed in basement strike-slip fault zone Shunbei area of Tarim Basin has achieved major breakthroughs. However, during drilling process area, problem mud leakage frequently interbedded Silurian sandstone and mudstone strata overlying target layer is very significant, it seriously affected normal wellbore stability. ...

Faults commonly form loci for high fluid flux in sedimentary basins, where fluids, rocks and deformation processes frequently interact. Here, we elucidate the interaction of flow, diagenesis near basin-bounding faults basins through a study vicinity (0–3.5 km) Dombjerg Fault NE Greenland rift system. Due to fault-controlled circulation, fault-proximal syn-rift clastics underwent pervasive calci...
