Under the epigenetic effects, ore-forming elements and associated elements are mainly formed in the form of chemical dispersion halo, and exist in the soil, and so it is very important to the survey of soil geochemistry. We take a new ore district in the area of volcanic rocks in southeast of Fujian province which was found in resent years for example, mainly introduce the method and significance of applying routine secondary halo method to prospecting work in this area, and then extend to regional research. The successful locating of blind ore bodies by secondary geochemical halo method in this example suggests that the secondary halo anomaly method is effec- tive and can be employed in search for other metal mineral prospecting in southeast of Fujian.
