Abstract Based on combination features of lithology,element geochemistry,TEX86 and many other indicators of Well Xike-1,Shidao Island,Xisha area,South China Sea,we aim to reconstruct the regional sea-level changes in Xisha area since the Early Miocene,and discuss the dominant factors of the carbonate platforms formation and development. Under the impacts of both the regional tectonic events in the South China Sea and the global sea level changes,it is found that the sea level in Xisha area shows a high-low-high-low variation trend during the Early Miocene,Middle Miocene,Late Miocene and Pliocene,and Quaternary. The sea surface temperature shows an overall downward trend from the Early Miocene to Pliocene. The combination features of lithology indicate that the Xisha carbonate platform initially formed in the Early Miocene,and it gradually flourished and developed in the Middle Miocene,then reached up to the peak in the Middle Miocene characterized as the formation of large reefs with lagoon facies. During the Late Miocene-Pliocene,the rapid increase of sea level and water temperature decrease led to the gradual shrinking and submergence of the carbonate platform which further shrinked in the Quaternary.It is found that two intense dolomitization events occurred in Xisha area during the Early Miocene and Late Miocene-Pliocene,respectively. These events are closely related to the exposure and erosion of carbonate platforms caused by regional sea-level drop. The carbonate platform evolution of Xike-1 is there presentation of the prosperity and extinction of the Cenozoic carbonate platform in the South China Sea. It was the comprehensive result of the Cenozoic tectonic evolution and global climate changes in the South China Sea.
