川滇黔桂地区石炭系地层发育 ,其地层划分对比清楚 ,沉积类型丰富 ,地表露头良好 ,是进行层序地层研究的理想场所。本文运用层序地层学的理论和研究方法 ,在详细的沉积学研究和精细的地层划分对比基础上 ,对川滇黔桂地区石炭系地层进行了精细的露头层序地层研究 ,详细阐述了层序建立和各种界面的露头标志 ,探讨了川滇黔桂地区石炭系地层的层序划分、层序区域对比。在此基础上 ,建立了研究区石炭系层序地层时空格架示意图 The strata of Carboniferous in Sichuan, Yunnan, Guizhou and Guangxi are well developed, and their stratigraphic division is clear. The sedimentary types are abundant and the surface is well exposed, which is an ideal place for the study of sequence stratigraphy. Based on the detailed sedimentology research and fine stratigraphic division and contrast, the paper uses the theory and research method of sequence stratigraphy to study the fine outcrop sequence stratigraphy of Carboniferous strata in Sichuan, Yunnan, Guizhou and Guangxi provinces. Order to establish and a variety of interface outcrop signs to explore the sequence stratigraphic division of the Carboniferous strata in Sichuan, Yunnan-Guizhou-Guangxi region, the order of the regional comparison. On this basis, a schematic diagram of space-time trellis of the Carboniferous sequence stratigraphy in the study area was established
