Abstract：Geometry and kinematics analysis of thrust-related fold system in piedmond is a frontier subject of structure and tec-tonics.These concepts and technical methods are relevant for the exploration and exploitation of hydrocarbon systems in pied-mont basins worldwide.The geometry and kinematics models of the faults and folds are established by using the 2D seismic profiles,drilling well logging data,and geological mapping data in the eastern Kuqa depression in the piedmont of Tianshan Mountains,China.The fault throw maps of the Tuziluke fault and the eastern Qiulitag and the shorting map of the eastern Qi-ulitag anticline have been drew.The results reveal that there are two types of fault in the eastern Kuqa depression,i.e.the steeply basement-involved faults and the low dipping thrust faults.In Tertiary,the steeply faults made the basement uplift and the Meso-Cenozoic squence erosion in the piedmont of Tianshan.The low dipping faults develop in Pliocene,which was detach-ment in the lower of Mesozoic and formed the blind imbricate thrust-related fold system in the Kuqa basin.
