摘要 在分析介绍野外地面γ射线谱仪器设备的基础上,针对低能γ射线谱的特点,结合地质调查项目,在金矿勘查工作中进行了实际应用。并以特例的形式,给出一个测点的实测γ射线谱曲线图、一条测线的综合剖面图和一个工作区的平面结果图,结果表明,低能γ射线谱能够在覆土覆盖的泥质片岩中较好地区分出含矿有利层位—炭质片岩的分布范围。

Abstract :This paper describes the field gamma ray full spectrometer, and discusses its practical application in geological survey, i.e. in the prospecting for gold deposits. The actual instance given in this paper includes a low gamma ray spectrum, a composite section of gamma ray spectrometry, and a plan of gamma ray spectrometry. Different rocks can be distinguished by measuring gamma ray low energy spectra.
