Based on the date analysis of seismic, logging and core, the feature of sequence stratigraphy in Tangyuan fault-depression is probed in this paper. One Ⅰ grade sequence, four Ⅱ grade sequence and twenty Ⅲ grade sequence are divided in this fault-depression, therefore the new sequence stratigraphic framework of Paleogene in Tangyuan fault-depression is established. In addition, according to regional tectonic feature the filling history of Tangyuan fault-depression is reconstructed. It is believed that the differential movement of boundary faults are the key factor for the Paleogene sedimentation of Tangyuan fault-depression.
