摘　　要：气体地球化学测量是一种极具前景的深部地球化学找矿方法。为了探索土壤气体测量方法在长江中下游成矿带运积物覆盖区内的隐伏矿勘查效果,本次研究采用多组分气体快速分析仪在黄屯金铜矿开展了土壤气体地球化学测量试验。结果显示,金铜矿体、断裂上方发育明显SO2、H2S气体异常。矿致异常分布范围和规模明显大于断裂引起的异常。根据异常特征可以区分矿致异常与断裂相关异常。本次试验结果表明土壤气体地球化学测量在黄屯金铜矿中的应用是有效的。Soil gas geochemical survey is one of the most promising deep geochemical prospecting methods.In order to research the effectiveness of the soil gas geochemical survey in looking for concealed mineral deposits in the drift load overburden area along the middle and lower Yangtze River reaches metallogenic belt,a pilot soil gas geochemical survey study was conducted in the Huangtun gold-copper deposit using the multi-component gas rapid analyzer.The results show that significant SO_(2) and H_(2)S anomalies exit above the copper-gold ore bodies and faults.The anomalies related to the mineral deposit are obviously bigger than those related to the faults in range and dimension.The two anomalies can be distinguished by their characteristics.The results of this study suggest that soil gas geochemical survey is effectively applicable to the Huangtun copper-gold deposit.
