Due to the far-field effect of the India-Asia collision, the Late Cenozoic normal faults are rather rare compared with the abnormally developed Late Cenozoic compressional structures in the Tarim Basin, a large Cenozoic sedimentary basin in the central Asia. The normal faults were often overlooked previously. The previous studies saw them as local structures derived from the compressional structures under the regional compressive tectonic setting. Our intensive systematic seismic interpretation discovered the Late Pliocene-Early Pleistocene normal faults in the Tarim Basin. They distribute mainly in the western half Tarim Basin. Two possible Late Pliocene-Early Pleistocene normal faults were found in the northeastern Tarim Basin. The normal faults appear both on tectonic unit boundary and within tectonic unit, in both rise and depression. They tend NW-SE and NE-SW forming a conjugated system horizontally, and combine into graben-horst structures or staircase-like cross-sections in profile. The Late Pliocene-Early Pleistocene normal faults in the Tarim Basin are regional but not local tensional structures. According to the fault growth-indexes, the normal faults were formed in Late Pliocene-Early Pleistocene. The normal faulting occurred in ca.3～2 Ma. The ca.3～2 Ma normal faulting phase in the Tarim Basin represents a regional tensional tectonic stage which is a tectonic pause between 2 successive thrust pulses under the far-field effect of the India-Asia collision.
