碳酸盐岩中粘土的去除及碳酸盐矿物稀土元素的测定方法

摘要

The rare earth elements contents of sedimentary carbonate minerals can be used to trace the redox condition of sedimentary environment. To determine the rare earth elements in the authigenic carbonate minerals accurately, it is very necessary to separate the terrigenous clays from carbonate rocks. In this paper, we have introduced several methods to remove clays and the methods to determine the rare earth elements in carbonate minerals.%碳酸盐矿物中的稀土元素的含量可以被用来示踪地球的氧化还原环境，碳酸盐岩中碳酸盐矿物与粘土矿物的分离是准确测定碳酸盐矿物中稀土元素含量非常必要的一步。本文分别介绍了几种去除粘土的方法以及碳酸盐矿物中稀土元素的测定方法。
