| The Sequence Stratigraphic Framework of the Sinian Wanlong Formation in Southern Jilin Province |
| The Sinian strata well developed in southern Jilin Province can be divided into Qiaotou Formation, Wanlong Formation, Badaojiang Formation and Qinggouzi Formation in an ascending order. The Wanlong Formation, dominated by all kinds of carbonate rocks in great thickness, is a key sequence that can be correlated with the Sinian strata in southern Liaoning and Xuhui areas. It is therefore necessary to establish the sea level change curve and the sequence stratigraphic framework of the Wanlong Formation. Based on the development of sedimentation, the overlying regulation of meter-scaled cycles, Fisher graphs and the maximum sea flooding events, the Wanlong Formation in southern Jilin Province can be divided into nine 3rd-order sequences. According to Sr and C dating data, the ages of the lower Wanlong Formation and Badaojiang Formation are 850 Ma and 812 Ma, respectively, and the age of every 3rd-order sequence is about 4.2 Ma. |
