Abstract: In order to analyze the controlling factors and sequence filling patterns of platform-basin sequence , the filling styles had been produced under variant controlling factors dominantly including sea-leave changing , sediment supply and structural settlement through taking the platform-basin sediments from upper Palaeozoic in south Guizhou-middle Guangxi area as an example.The results show that the association of sea-level changing contained the following four styles of quick transgression-quick regression , gradual transgression-quick regression , quick transgression-gradual regression and gradual transgression-gradual regression.Correspondingly , there were four sequence filling patterns of TST=HST 、 TST≥HST 、 TST 《 HST and TST= HST respectively.Meanwhile , the sediment supply played a dominant role on the material composition and types of platform-basin.The manifestation of controlling effects from structural settlements indicated the filling pattern variance of platform-basin sequence mainly caused by the different modes of syndepositional fracture and base fluctuation.The final filling patterns of platform-basin sequence were the consequences of all the controlling factors.
