We apply a deep learning model to segment and identify rock characteristics based on Structure-from-Motion orthomap digital elevation of rocky fault scarp in the Volcanic Tablelands, Eastern California, USA. By post-processing results, we build semantic map analyse trait distributions. The resulting contains nearly 230 000 rocks with effective diameters ranging from 2 250 cm. Rock distributions...

The F317 fault, as a major tectonic zone in the Jianshan mine area, influences geotectonic features and geomechanical properties of area. Mining operations need to be conducted within these systems, so it is important fully study understand characteristics evolution systems develop reasonable mining plans safety measures. Aiming at problem that existence fault affects stability west road during...

We describe here the results of characterization subsurface structures in an area south-eastern edge Bohemian Massif, Austria by high-resolution geophysical survey techniques and advanced analysis methods potential fields. The employed included field multiscale for source-edge location sources at depth. Our confirmed presence already known structures: Diendorf Fault Moldanubian Shearzone are cl...

The dominant structural feature of Jordan is the north-south trending Dead Sea Rift. It is an active part of the African-Syrian Rift, which extends for about 6000 km, from east Africa through the Red Sea, Wadi Araba, Dead Sea, Jordan Valley to south Turkey. The groundwater aquifers of Jordan are divided into three main complexes: A deep sandstone aquifer complex, an Upper Cretaceous aquifer com...

[1] The Transantarctic Mountains (TAM) define the western flank of the West Antarctic rift system. Cape Surprise, near the Shackleton Glacier in the central TAM, is the only location along the range’s >3500 km length where upper Paleozoic Beacon Supergroup strata are down-faulted to near sea level. Previous studies have inferred a range front master normal fault accommodates extension and rock ...

[1] Earthquake nucleation requires reduction of frictional strength = ( p) with slip or slip rate, where , n, and p are the friction coefficient, normal stress, and fluid pressure, respectively. For rate state at fixed ( p), instabilities can occur when d ss/dv < 0, where ss is the steady state friction and v is slip rate. Shear heating increases p and, if dilatancy and pore pressure diffusion ...

Allochthonous masses are common structures in Zagros fold-thrust belt. They are generally considered as collapse structures formed by the influence of gravity and in rock units with competency contrast. However, large allochthonous masses mapped in Dowgonbadan area in Dezful Embayment near the Mountain Front Fault (MFF) of Zagros show characteristics different from the belt common collapse stru...
