| Abstract: | Sichuan Basin may be divided into east Sichuan parallel ridge-and-valley area, low mountain-hill area around the basin, central Sichuan hill area and west Sichuan plain area. Sampling objects and sampling densities in different areas are discussed. Geochemical exploration has achieved good result of the prospecting of nometallic and metallic mineral resources in the east Sichuan parallel ridge-andvalley area and in low mountain area around the basin. Soil geochemical data can serve agriculture and environmental protection in central Sichuan, providing geochemical basis for scientifically applying fertilizer, reasonablly growing and improving the soil. It is proved that geochemical exploration is effective on the oil-gas prospecting in the west Sichuan plain area. |
