In the Cenozoic strata of Leqiong area in Guangdong province, many predecessors have done a lot of work and created many stratigraphic names, especially a group of Zhanjiang group. The contents of the strata vary greatly. Through the work in recent years, opinions gradually converge. On the basis of previous works, the author attempts to discuss the comparisons of the Cenozoic strata in the area and their times from the combined characteristics of gastropods and the drilling data used by comrades of production units and field teams.
