Four arcuate zones of both strike-slip faults and thrust faults with associated ramp anticlines dominate the structures in southern Ningxia. Deformation in these zones indicates that a component of left-slip displacement is transferred into crustal shortening on north-south-trending folds and thrust faults. The average Quaternary slip rate along the Haiyuan-Liupan Shan fault zone is 5-10 mm/yr, and that along the Tianjin Shan-Mibo Shan fault zone is about 1.5-2.7 mm/yr. The amount of offset and rate of slip along the Yanton Shan and the Niushou Shan-Daluo Shan fault zones are unknown, but the topography of the mountains suggests that the rates of slip along these zones is lower than that of the Haiyuan-Liupan Shan fault zone. Deformation in northern Ningxia is dominated by normal faulting and extension. The Helan Shan rise about 2,000 m above the Yinchuan basin, reportedly filled with a few kilometers of Cenozoic sediments. The average rate of vertical separation in Quaternary time along the East Helan Shan fault is estimated to be at least 0.5-0.8 mm/yr. Opening of the Yinchuan graben is probably partly related to left-lateral slip on the Niushou Shan and Daluo Shan fault zone. The northeastern margin of Tibetan Plateau is probably being elevated by the irregular growth of convergent and left-slip structural zones. The evolution of deformation along the Haiyuan-Liupan Shan structural zone probably foreshadows the future deformation in the ranges north of it. Left slip and shortening within the Ningxia region appears to accommodate less than 20-25 km of east or northeast displacement of crustal fragments of the northern Tibetan Plateau. Large-magnitude lateral transport of crust with respect to the area to the east has not taken place within the part of the Ningxia region covered by this study. This content is PDF only.
