Application of γ Spectra Measurement in the Research of Lake Sediment and Palaeoenvironment

Abstract:

Xigeda Formation layer, which is widely distributed in Panzhihua area, is researched by the method of γ spectrum measurement. Qinglongshan Xigeda Formation profile is measured by the low-background multi-channelγenergy spectrometer in Panzhihua, the change rules of radioactive elements, including URa, Th, K, Ir and Ira on the profile are analyzed in detail. The characteristics and palaeoenvironmental significance of the sediment layer on the profile is researched by combining the geological features. The results show that the contents of radioactive elements in Xigeda Formation profile reduce obviously from the old to the new layer and change regularly and the radioactive characteristics are consistent to the sediment geological features. All these show that the γ spectrum method is a good one for the study of lake sediment and palaeoenvironment.
