摘要
地面伽马能谱测量作为地质填图的辅助手段应用于浅覆盖区是一种尝试。利用地面伽马能谱测量数据的预处理来尝试消除浅覆盖层对能谱测量的影响,通过野外试验数据和实测剖面数据的分析,进行了地表植被、局部干扰、测量几何条件、Th、K元素垂直分布分析,获得了数据预处理的简单方法,经过实测剖面的对比,证明方法是可取的。
The ground gamma spectrometry as an auxiliary means for geological mapping in areas with shallow overburden areas is a new trial. This paper tried to resolve the problems caused by the shallow overburden strata on the ground gamma spectrometry by the data pre-processing. The method of data pre-processing was found based on field test data and the analysis of measurement data including the analysis of surface vegetation, local disturbance, measurement geometry, vertical distribution of radioactive elements Th and K. By comparison with the measured profile, this method was shown useful.
