土壤中CO_2、SO_2和H_2S气体测量:一种适用于覆盖区找矿的化探方法

Soil Air Carbon Dioxide,Sulphur Dioxide and Hydrogen Sulfide Measurements as a Guide to Concealed Mineralization

为了研究CO2、SO2和H2S气体测量方法在覆盖区隐伏矿勘查的应用效果,采用气体快速分析仪对内蒙古拜仁达坝银铅锌矿、江西景德镇朱溪钨铜矿和江西乐平月形铜矿开展了CO2、SO2和H2S气体测量试验性研究。结果表明,采用CO2、SO2和H2S气体测量,能有效发现隐伏矿的信息,勘探深度能达到1 000m。该方法操作简便,可以现场读数,是一种非常有前景的覆盖区找矿方法。

To understand the effectiveness of CO2, SO2 and H2S gas measurements in the exploration for concealed mineral deposits in covered areas, preliminary pilot studies were undertaken by employing CO2, SO2 and H2S gas measurements with rapid gas analytical techniques for the Bairendaba Pb-Zn deposit, Zhuxi W-Cu deposit and Yuexing Cu deposit. The results demonstrated that the utilization of CO2, 802 and H2S gas measurements favors the valid discovery of the mineralized information around deeply buried mineral deposits. Furthermore, the exploration depth can reach levels up to 1 000 m. This method is easy to use and can directly produce analytical data from the field, thus making it a powerful mineral prospec- ting technique in covered areas with great potentials.
