| Abstract: | Based on the study of rock assemblage characteristics, sedimentary environment, palaeophyte features etc. of fluvial facies coarse clastic rocks in Ledong County, Hainan Province, a new lithostratigraphic unit, Qiutangling Formation is founded, which is different from Wayao Formation of Changchang Basin and Changpo Formation of Changpo Basin in Hainan Island. The establishing of Qiutangling Formation of Oligocene-Miocene has improved the Cenozoic lithostratigraphic unit of Hainan Island and supplied new data for tectonic-magmatism evolution in Late Mesozoic and basin development history in Early Cenozoic in Hainan island. |
