为了在成矿区带和矿集区找矿工作中有所突破，开展工作区内水系沉积物和土壤剖面地球化学的试验是一项不容忽视的工作。江西九岭钨铜多金属矿集区水系沉积物、典型土壤剖面地球化学试验表明：①在赣北九岭地区寻找岩浆热液型钨、铜多金属矿床的最佳指示元素是W、Sn、Cu、Mo、Bi、Ag、Cd、F；②地球化学普查（1∶25万-1∶5万）水系沉积物的采样位置应以一级水系的采样为主，辅以少量二级水系，采样粒度以10~60目的水系沉积物为宜；③地球化学详查（1∶5000-1∶10000）土壤地球化学测量采样层位为残积土壤B层，采样深度为20~40cm，采样粒度20~40目，或小于40目均可显示出较好的异常。

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.
