| 摘 要： | 提出在全谱测量基础上对自然γ能谱的低能谱段进行研究，将天然γ射线谱的低能部分看作是天然γ射线与物质作用的结果，增加反映岩石物质成分的参数。这样，测量结果提供的不仅有放射性元素分布的数据，而且还有直接反映岩性变化的资料，可用于地质填图及金属矿地质工作。

| Abstract: | It is usual to use hard energy range（>1.0 MeV） in natural gamma-ray spectrum for determining the concentration of uranium,thorium and potassium by natural Gamma-ray spectrometry.However,the soft energy range which implies information about meterial compositions in not used.The low energy-peak in natural gamma-ray spectrum in the result of interaction between natural gamma-ray and meterials（eg.rocks）.According to the rebtionship of antural low energy gamma-ray peak with the meterial composition,the different kind of rocks can b identufied.This idea can be expected to be used in geological mapping,mineral exploring,deposits evaluation.There is not environment pollution when it is applied. |
