应用γ能谱法找金研究

A study of gamma-spectrometry on looking for gold ore

本文介绍应用γ能谱法在山东某矿区找金的可行性研究。 从实测结果可知,放射性元素在不同岩性中的含量以蚀变带最高,混合花岗岩次之,石英(矿)脉中最低。在横穿各条矿脉的测量剖面上,都出现了与矿脉相对应的Th、K及Tc(放射性元素总含量)低值异常,三者各自的峰背比值分别为0.5—1.0、0.3—0.7和0.3—0.7之间,都能反映矿脉的存在。

A feasibility study has been made on looking for gold with gamma-spectrometry in an area of gold-quartz vein, Shandong Province.By surveying the data, we concluded that the radioactive element contents are higher in the alteration zone, middle in the mixed granite and lower in the ore veins. There exist some anomalies of potassiume thorium and total content on the sections across the ore veins. The linked lines of allpoints just show the strides of the ore veins.
