The eastern part of the Ordos Block, also called Fen-Wei graben, is located at the boundary of eastern and western China, which is a geotectonic decoupling region and an earthquake-prone area. The high resolution crust and upper mantle shear velocity structure in the study area is the key to study the geological formation and evolution of the Fen-Wei graben. In addition, the study is also beneficial for a better understanding of the earthquake pregnant system and focal mechanisms in the region.
