烃、汞综合气体测量在湖南浏阳–醴陵官庄金矿区找矿预测中的应用
Application of Hydrocarbon and Mercury Gas Measurement to Gold Ore Prospecting Prediction in Liuyang-Liling Guanzhuang, Hunan
摘要: 浏阳–醴陵官庄地区成矿地质条件优越，深部具有巨大的资源潜力，利用新技术在区内开展“攻深找盲辨难”是当前找矿工作的迫切需求。本次采用烃、汞综合气体测量法在区内开展找矿预测，布设了4条实验性剖面，共采集土壤样品240件。通过分析吸附相态汞和烃类组分在剖面和平面上的分布特征，发现在矿脉地表出露点附近，汞、烃组分存在相对高值异常，在矿体上方，汞、烃组分含量都低于背景值，表明，烃、汞综合气体测量对工作区金矿找矿具有指示意义。在香禾田金矿西南侧，发现大面积的烃类和汞异常，整体呈“港湾”状，浓集效果良好，推测该区为有利的深部找矿靶区，值得进一步工程验证。
Abstract: Liling-Liuyang Guanzhuang district has a strong position to become mineral substance. In the deep part, it has enormous resource potential. So the most urgently demand for current ore prospecting work is using new technologies to carry out “exploring deep deposit, identifying the difficulty” in this district. At this time, in order to carry out prospecting prediction, a total of 4 experimental profiles have been set up by using the Hydrocarbon and mercury gas measurement, and the 240 soil samples are collected. By analyzing the distribution characteristics of the adsorbed phase mercury and hydrocarbon components on the profile and plane, it is found that there are relatively high value anomalies of mercury and hydrocarbon components near the surface dew point of the vein. Above the ore body, the content of mercury and hydrocarbon components is lower than the background value, which indicates that the comprehensive gas measurement of mercury and hydrocarbons has an instructive significance for gold prospecting in the working area. On the southwest side of the Xiang Hetian gold deposit, a large area of hydrocarbon and mercury anomalies has been developed, which is in the shape of harbor as a whole. The effect of concentrations is satisfactory, it is presumed that this area is a favorable deep prospecting target area, which is worthy of further engineering verification.
