| The Ages of Volcanic Activity in West Liaoning Province and Rehe Biota |
| The ages of volcanic activity and the lacustrine strata with paleontological fossil in Sihetun of west Liaoning Province were dated by K-Ar and Ar-Ar chronologic methods. In addition, the time of Rehe biota was inferred from the relationship between the volcanic activity and the extinction of Rehe biota. |
