Abstract: Abstract：Carbonate rock deposition of great thickness occurred in Upper Carboniferous period in southern Guizhou, characterized by wide distribution, integrated strata, well stratigraphic continuity, diverse depositional environments and abundant lithologic combinations. Southern Guizhou is an ideal location for studying carbonate rock sedimentary characteristics and sequence stratigraphy. Based on field measured data (mainly dependent on Jiadaozhai section of Dushan area in association with other sections), this paper employed the relevant theory and methods of sedimentology and outcrop sequence stratigraphy to analyze sedimentary characteristics of outcrop, and then divided sequences and made correlation. It is recognized that southern Guizhou mainly developed restricted platforms, open platforms, platform marginal slopes, and platform basins, whereas Dushan developed only restricted platforms and open platforms. In general, they appear as NNE–trending platforms and SSW-trending basins. The characteristics of sequence filling show that sequence filling was controlled by the third-order sea-level changes at the early stage, and was controlled by both tectonic activity and third-order sea-level changes at the late stage, finding expression in filling and leveling in the carbonate platform.
