桂西地区核地球物理学α卡法、γ能谱法、X射线荧光法现场勘查金矿研究

The Study of Exploration Gold Deposit by Using α Card Method,Gamma—ray Spectmetry Method,X-ray Fluorescence Method of Nuclear Geophysical Methods in The West of Guangxi

本文论述了应用核地球物理学中的α卡法、γ能谱法、X射线荧光法现场综合勘查金矿的理论基础、方法技术及应用实例。首次在同一金矿区综合应用3种方法,实践表明:应用α卡法可圈出与金矿密切相关的构造破碎带;应用γ能谱法可进一步划分金矿化带;应用X射线荧光法划分金矿层厚度,指导地质人员有目的的采样。

In this paper,the theory and technology of explorationg gold deposit by using nuclear geophysical methods (α Cardmethod,gamma—ray spectrometry method,x-ray fluorescence method) are discussed.It is the first time to use these threemethods in same gold deposit.The results show constructure broken belts concerning gold deposit can be found by using αcard method,the gold mineralization can be delimited by using gamma—ray,spectrometry method,the grade of gold are canbe determined by using X-ray fluorescence method and instruct sampling.
