摘要
放射性同位素多道X荧光分析是一种核分析方法 ,具有快速、无损、低成本及多元素分析等优点。以华蓥山地区庙坝下三叠统嘉陵江组剖面为例 ,采用放射性同位素多道X荧光分析方法 ,测定了地层中Ca、Fe、Sr、Ba元素的照射率 ,并进行了化学地层和层序地层的初步研究 ,取得了较好的效果。
Radioisotope multichannel X ray fluorescence method is a kind of nuclear geophysical prospecting technique with high speed, non destruction of samples, low cost and multi element analysis. By using this technique, the radioactive intensities of Ca, Fe, and Ba elements are measured from the Jialingjiang Formation of the Lower Triassic in the Miaoba section, Huayingshan region. The results of measureement are successfully applied to the study of chemostratigraphy and sequence stratigraphy, which shows wide application perspectives of this method.
