Tectonic geomorphology in the Hexi Corridor, north-west China

The Hexi Corridor is a Cenozoic foreland basin system at the north-eastern margin of the Qinghai-Tibet PIateau. Active faults, having clear geomorphological expression, are mainly NW-trending reverse-sinistral faults and NNW-trending reverse-dextral faults. From the south-west to the north-east, landforms can be divided into three parallel zones arranged along the WNW faults. Longitudinally, three transverse uplifted blocks divide the Hexi Corridor into four subbasins. North-eastward motion of the Qinghai-Tibet Plateau and eastward motion of the north-east part of the Plateau resulted in compressive and shear deformations and controlled the geomorphological pattern in the Hexi Corridor.Geosciences, MultidisciplinarySCI(E)9ARTICLE3345-3521
