Based on the analysis of prototype basin, according to the relationships between provenance characteristics and the basin types and the structural features of strata, The Late carboniferous basin in the Ludong-Wucaiwan area is systemically demonstrated, which include tectonic setting and distribution range. Based on fine interpretation of the 2D seismic lines, the comprehensive core statistics, seismic facies analysis and inversion information, we think there are two modes of rifts in late carboniferous in the study area. In Wucaiwan and Dongdaohaizi regions it mainly develops the single fault rift, and in Sannan-Dishuiquan region it mainly develops the double fault rifts. Two modes of rifts are filled by lots of volcanic rocks, and the development and distribution of the volcanic rocks are mainly controlled by the faults in gentle slope area.
