Since a year ago， the international rice price has been rising continuously. As one of the important materials of chemical fertilizers and pesticides，the phosphorite price has also been going up. Therefore, the prospecting for phosphorite seems to be very important and urgent. The Chaoyang phosphorite deposit is the largest phosphorite deposit in East China. Starting with the 1∶200000 geochemical anomalies from the drainage sediment survey, this paper analyzes and evaluates synthetically the oreprospecting value of the geochemical anomalies in the periphery of the Chaoyang phosphorite deposit in Jiangxi Province and, on such a basis, points out that the potential is very large. The phosphate prospecting targets in Wuchun and Wudu are optimized in the hope that the work is helpful to the prospecting for phosphorite resources in the peripheral areas.
