Abstract: The Tan-Lu fault zone experienced intense extensional activities during the Late Cretaceous to the Early Paleogene. Thus, faulted basins were developed along the fault zone. The extension started from the earlier Late Cretaceous in the middle and southern segments of the fault zone whereas from the earlier Early Paleogene in the northern segment, showing a northward migration through time. The extensional activities present pulsative and progressive development. It has been identified that six extensional events took place from the Late Cretaceous to Early Paleogene. Correspondingly, depositional response occurred in the fault controlled basins. The extensional activities increased their influence and scope progressively. The extensional migration and pulsative development are related to the contemporaneous Pacific Plate movement.
