地气(氡气)测量方法寻找隐伏含矿断裂试验

摘要

介绍了FD-3017RaA测氡仪工作原理和野外工作方法.对典型不同矿种含矿断层剖面分析表明:在断层破碎带上方,氡异常的主峰位置反映构造破碎带在地表出露位置,利用测量氡进行寻找隐伏断裂效果很好,特别对于与断裂构造(断层、节理、劈理等)有关系密切的矿床,可以将氡气测量作为寻找隐伏矿床的辅助手段.%This paper describes in brief the principle and field work methods of the FD-3017RaA radon measuring instrument. An analysis of ore-bearing profiles in different kinds of typical ore deposits shows that, over the fault shatter zone, the major peak of the radon anomaly reflects the surface exposure location of the structural shatter zone. It is thus concluded that the application of radon measurement to the prospecting for concealed fractures is very effective, and that radon measurement can be especially used as an auxiliary means in search for concealed ore deposits closely related to fracture structures such as faults, joints and cleavages.
