Geomorphic parameters, which reflect the migration of drainage divide responses, are widely used to assess tectonic activity. There have been several large earthquakes in history Hetao Basin, within Sertengshan Piedmont Fault is important. This study highlights certain references for regional seismic risk assessment. Few studies conducted on area from perspective geomorphic parameters. In this ...

The mountainous, glaciated island of South Georgia is the crest one most isolated fragments continental crust on Earth. It located approximately 1700 km east southern termination Andean Cordillera America. primarily composed Lower Cretaceous turbidites , infill a marginal basin floored by stretched and ophiolitic crust. Remnants volcanic arc are preserved offshore islands to southwest. Pacific ...

The style and evolution of tectonics on the terrestrial planets differ substantially. The style is related to the thickness of the lithosphere and to whether the lithosphere is divided into distinct, mobile plates that can be recycled into the mantle, as on Earth, or is a single spherical shell, as on the moon, Mars, and Mercury. The evolution of a planetary lithosphere and the development of p...

The low-velocity zone (LVZ) is a persistent seismic feature in a broad range of geological contexts. It coincides in depth with the asthenosphere, a mantle region of lowered viscosity that may be essential to enabling plate motions. The LVZ has been proposed to originate from either partial melting or a change in the rheological properties of solid mantle minerals. The two scenarios imply drast...
