摘　　要：通过测定特征放射性核素的含量变化以及利用成矿组分中一些高品位共生元素与金密切的相关关系 ,可利用地面伽马能谱与X荧光测量在现场快速揭示金矿化的存在 ,同时对金的品位进行准定量评价 ,以及指导野外地质采样和山地工程。According to the variation in content of characteristic radioactive nuclide and the close relationship between high grade associated elements in ore forming components and gold,the ground gamma ray spectrometry and X ray fluorescence slectrometry can be used to reveal the existence of gold mineralization rapidly in field and make semi quantitative evaluation of gold grade.This is of great significance in guiding field geological sample collection and mountain land engineering.
