摘要
讨论在大兴安岭地区进行地质填图中浅覆盖层对伽马能谱测量的影响问题。通过放射性元素的取样分析、岩石—土壤的矿物分析以及实测剖面分析,得知了伽马能谱测量的影响因素,从而为应用伽马能谱测量解决地质填图中的问题提供了依据。
As ground gamma spectrometry can only detect the shallow part, overburden layer will affect the value of survey in a certain degree. This paper discussed the problem of shallow overburden layer affecting ground gamma-spectrometry during geological mapping in Daxin'anling area. By sampling the radioactive elements, and analyzing the minerals in rock-soil as well as the field measure profiles, a few influence factors in gamma spectrometry application were obtained, and some basis and evidences for geological mapping have provided.
