Structural characteristics of Wuboer thrust belts in the foreland of West Kunlun Mountain

The Wuboer thrust belt consists of three rows of thrusts from south to north,including the West Kunlun thrust body in the southwest part,the arc Wuboer Fault in the northeast part,and the Wuboer Basin between above two parts.The field observation and structural analysis of seismic section show that the Wuboer Fault slides along the anhydrite-mudstone layer located at the bottom of Eogene and thrusts up to ground surface.The bright unconformity reflection wave near the surface responds to the bottom of the Lower Pleistocene.The Wuboer thrust construction started at the Late Pliocene and is active at present.The east and west lips of Wuboer Fault are higher than middle part of that.The fault is shaped with saddle.The east fragment of structure is side ramp and characterized by strike slip.The west fragment of structure thrusts up to ground surface.
