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 SO2 and H2S 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.
