Paleozoic source rocks from 16 sections of frontal Micangshan-Daba are studied in this article by the quantity,type and maturity of the organic matter and the lithology. The results show that the hydrocarbon source rocks are mainly from the lower Cambrian and the lower Permian,and developing source rocks occur in some areas of the lower Silurian and the upper Ordovician. Comprehensive analyses of geochemistry characteristics of the source rocks suggest that the source rocks are mainly type I and type II which have great hydrocarbon generation ability. The source rocks at over\|maturing stage are mainly over-mature source rocks,but still have gas generating capacity.
