Accretionary wedge earthquakes usually occur in the overriding crust close to trench or above cold nose of mantle wedge. However, mechanism and temperature properties related slab dip angle remain poorly understood. Based on 3D thermal models estimate subduction plate structure, we investigate distribution Alaska, which has a varying along trench. The horizontal distance wedge-earthquake hypoce...

Abstract. Observations of sediments at subduction margins appear to divide them into two classes: accretionary and erosive. Accretionary are dominated by accretion thick piles (>1 km) from the subducting plate, while tectonic erosion is favored in regions with little or no sedimentary cover (<1 km). The consequences styles for dynamics remain poorly resolved. In this study, we used 2-D nu...

The Durkan Complex is a key tectonic element of the Makran accretionary prism (SE Iran) and it has been interpreted as representing continental margin succession. We present here multidisciplinary study western Complex, which based on new geological, stratigraphic, biostratigraphic data, well geochemical data volcanic meta-volcanic rocks forming this complex. Our show that complex consists dist...

[1] Orogenic structure appears to be partially controlled by the addition to and removal of material from the mountain belt by tectonic accretion and geomorphic erosion, respectively. We developed a coupled erosion-deformation model for orogenic wedges that are in erosional steady state and deform at their Coulomb failure limit. Erosional steady state is reached when all material introduced int...

The structural geometry, kinematics and density structure along the rear of the offshore Taiwan accretionary prism were studied using seismic reflection profiling and gravity modeling. Deformation between the offshore prism and forearc basin at the point of incipient collision, and southward into the region of subduction, has been interpreted as a tectonic wedge, similar to those observed along...
