Late Cemozoic normal faults were discovered for the first time in Tangguzibasi depression of southern Tarim Basin based on systematic seismic interpretation. The Late Cenozoic normal faults discovered in Tangguzibasi depression extend mainly in NW-SE direction. Only 2 Late Cenozoic normal faults on the northwestern boundary of Tangguzibasi depression extend in NE-SW direction. The normal faults combine into graben and horst structures in profile. On the basis of the analysis on the variation of the fault displacement, the normal faulting began in Late Pliocene (～3 Ma), and lasted in Early Pleistocene and ceased at ca. 2 Ma. They were formed in the same time as those on the boundaries of Awati sag, NW Tarim. The 3～2 Ma normal faulting occurred under a regional extensional tectonic background, and represent a tectonic pause in the Late Cenozoic far-field effect of the India-Asia collision.
