Abstract: For the purpose of finding a breakthrough in the mineralization belt and the ore concentration area, geochemical test of stream sediments and soil profile is an important link which should not be ignored. Through testing the stream sediments and typical soil profile in the Jiuling tungsten-copper polymetallic ore concentration area of northern Jiangxi Province, the authors have reached some geochemical conclusions: ①in Jiuling of northern Jiangxi province, the best indicator elements for magmatic hydrothermal type of tungsten-copper polymetallic deposits are W, Sn, Cu, Mo, Bi, Ag, Cd and F; ②at the geochemical general survey (1∶250000—1∶50000) stage, the stream sediment’s sampling location should be given priority to the first-order stream, with subordinate attention paid to the second-order stream, and the sampling size of 10~60 mesh for sediments is proper; ③at the geochemical detailed survey (1∶5000~1∶10000) stage, the sampling horizon of geochemical soil survey is eluvial soil horizon B, the sampling depth should be 20~40 cm, and the sampling size ought to be 20~40 mesh or <40 mesh, which can well show geochemical anomalies.
