摘要
本文简要阐述了地面伽玛能谱方法找金的基本原理,列举了双王金矿床及葫芦沟金矿床的实验成果,分析了地面伽玛能谱方法寻找金矿的应用前景。作者认为:地面伽玛能谱测量可以作为一种间接找金方法用于金矿找矿的各个阶段。在一定条件下,可用于指导勘探和开采工程的布署。不同成矿地质环境的金矿床,具有程度明显不同的地面伽玛能谱特征,与碱性成矿环境有关的金矿床,找矿效果明显。
The basic principle of ground gamma-ray spectrometric survey for gold is briefly des- cribed. Experimental results of Shuangwang and Hulugou gold deposits are enumerated. Application potential of ground gamma-ray spectrometric survey for gold exploration is analyzed. The author considers that ground gamma-ray spectrometric survey as an indirect technique for gold exploration can be applied to prospecting for gold in various stages of gold exploration. Under given conditions, it can be applied to guide exploration and ar- range mining engineering. Gold deposits formed in different geological environments posses evidently different ground gamma-ray spectra. The prospecting effect is obvious for gold deposits associated with alkaline metasomatic environments.
