In order to develop effective measures ensure the operational condition of development workings behind face in conditions soft footwall rocks, construction local reinforced zones under protection means has been proposed. The presence such allows transferring current load deep into massif and creating a stable foundation protective structure. results researches concerning establishment rational ...

The capacity of oceanic crust to record geomagnetic polarity reversals makes sea-surface magnetic anomalies an essential tool study plate tectonics. are usually well-defined at magmatic spreading centers, but distorted and eventually disappear on magma-poor mid-ocean ridges such as the ultraslow Southwest Indian Ridge (SWIR), making their interpretation difficult. We attribute variability SWIR ...

ground differential movements due to faulting have been observed to cause damage to engineered structures and facilities. although surface fault rupture is not a new problem, there are only a few building codes in the world containing some type of provisions for reducing the risks. fault setbacks or avoidance of construction in the proximity to seismically active faults, are usually supposed as...

[1] We present a unified analysis of physical properties of cataclastic fault rocks collected from surface exposures of the central Alpine Fault at Gaunt Creek and Waikukupa River, New Zealand. Friction experiments on fault gouge and intact samples of cataclasite were conducted at 30–33 MPa effective normal stress (sn′) using a double-direct shear configuration and controlled pore fluid pressur...

The Cardenchosa pluton is a Lower Carboniferous Variscan granite located in the southwestern Iberian Massif. It intruded along the contact between the Sierra Albarrana and Azuaga tectonic units. To the northwest the pluton connects with the leftlateral Azuaga fault. The pluton appears in the footwall of the low-angle normal Casa del Cafe fault, which crops out to the west of the granite. Gravi...

Chemical maps of garnet are the key to understand the tectonometamorphic evolution of the metamorphic rocks. They provide useful information on element distribution, diffusion, and mechanical truncation of crystal. In the Himalayas, studies on ultra-high pressure rocks denudated along the Main Central Thrust (MCT) revealed the great displacement along this intracontinental shear zone. Pêcher (1...

On 28 August 2009, one thrust-faulting Mw 6.3 earthquake struck the northern Qaidam basin, China. Due to the lack of ground observations in this remote region, this study presents high-precision and high spatio-temporal resolution post-seismic deformation series with a small baseline subset InSAR technique. At the temporal scale, this changes from fast to slow with time, with a maximum uplift u...
