%X By analysis and study of bulk of wells and outcrops, on the basis of generalizing various structures and stratigraphic classifications of Cambrian strata of different periods in south Sichuan basin, in terms of lithostratigraphic characteristics and comprehensive analysis of its paleontologic characteristics and rock resistivity, the Cambrian strata in south Sichuan basin can be divided into four formations: Jiulaodong and Longwangmiao Formations of Lower Cambrian, Gaotai Formation of Middle Cambrian, and Xixiangchi Group of Middle-Upper Cambrian. Study on the stratigraphic characteristics and distribution indicates that the Jiulaodong Formation of Lower Cambrian mainly develops clastic rock with little carbonate rock, the Longwangmiao Formation of Lower Cambrian mainly develops marine carbonate, the Gaotai Formation of Middle Cambrian develops mixing deposit of clastic and marine carbonates, and the Xixiangchi Group of Middle-Upper Cambrian develops marine carbonates. The thickness of each Cambrian Formation (Group) in the study area decreases gradually from southeast to northwest.
