he Paleogene Kongdian Formation in the southern Huanghua Depression is the earliest deposited strata in the Bohai Bay rifted basin. The Kongdian Formation was distributed in the inclining graben constituted by the Cangdong fault and Xuxi fault. Based on the comprehensive analyses of the profile structural characteristics,the isopach of remnant strata thickness，the sequence configuration and fault growth index,it is concluded that the southern Huanghua Depression experienced a tectonopalaeogeography evolution from a stretching depressional basin to a stretching rifted basin during the deposition of the Kongdian Formation. During the deposition of Members 2 and 3 of the Kongdian Formation,large amounts of smallscaled normal faults were developed in the southern Huanghua Depression. These faults were evenly distributed, the moving strength was weaker and their differences were smaller. The syndepositional active faults had little influence on subsidence and deposition in the depositional area. The sequence configuration was characterized by paralleling,subparalleling pattern. Marginal facies was not developed in the upthrow of the Cangdong and Xuxi faults. These characters indicate that the Cangdong and Xuxi faults were possibly not the boundaries controlling the deposition of Members 2 and 3 of the Kongdian Formation. During the deposition of Members 2 and 3 of the Kongdian Formation, the study area was characterized by a ''depressional rift'' or ''depressional fault'' framework. During the deposition of the Member 1 of Kongdian Formation, the normal faults moved strongly and the difference of the moving strength was obvious. The stretching deformation was mainly concentrated in the inner part of the depositional area. Several largescaled trunk faults and the Cangdong and Xuxi faults were marginal faults controlling the depositional area. The deposition was dominated by a wedgelike sequence configuration. The tectonopalaeogeography was characterized by a stretching ''rift'' setting and it complicated the basin origin during the deposition of Members 2 and 3 of the Kongdian Formation.
