摘要
简要说明使用放射性核素源激发,Si(Li)半导体探测器-多道分析器系统测定碳酸盐岩样品中铁、锶及其他微量元素的实验条件、工作方法,并讨论了这一方法在川西北甘溪剖面上泥盆统碳酸盐岩研究中的应用。基于对岩石中铁、锶相互关系的分析和它与原始沉积环境、粘土含量、白云石的稳定化以及沉积溶液性质的关系,为沉积环境的研究和白云岩化模式的建立提供了重要的基本数据。
The present paper explains briefly the experimental condition, working method and analytical results of determiningthe contents of iron, strontium and other elements in the samples by means of Si(Li)semiconductor detectort-multichannelanalytical system, and discusses the application of the results to the study of dolomitization of Upper Devontian carbonate rocksalong the Ganxi profile in northwestern Sichuan. Based on the analysis or relationship between Sr, Fe contents of the rocks andsuch factors as original sedimentary facies, clay content, stability of dolomite and properties of diagenetic solutions, it providesvaluable basic data for the research on diagentic environment and the establshment of a model for dolomitization.
