| Abstract: | The Cretaceous of the Ledong Basin on the Hainan Island is intensively studied. The alluvial facies of rocks in the upper part of the original Baowan Formation are separated and named Changmao Formation. The present Baowan Formation is defined below the Changmao Formation and consists of fluviolacustrine deposits. The Changmao Formetion is conformable with the present Ledong Formation and contains fossil spores and pollen grains. Its age ranges from latest Early to Late Cretaceous. |
