摘　　要：绿泥石岩型滑石主要成分是斜绿泥石,因镁和铝的含量相对较高,测试过程中干扰较大,为消除基体效应所带来的影响,故采用混合熔剂高温熔融制样和X射线荧光光谱法同时测定绿泥石岩型滑石中的多元素分析,本法不仅可以测定地质样品绿泥石岩型滑石中多元素,而且测试周期短,实验流程简单,样品用料少,可测定不同地质样品中的化探样品和化学样品,经实验测试结果的比对,结果准确,可靠,而且测量结果的精密度好,准确度高,数据和化学法的结果基本一致,但比化学法成本低,流程短,适用于绿泥石岩型滑石中各主要元素的分析。The main component of green mud Shiyan type talc is clinochlore, because the content of magne- sium and aluminum is relatively high, a large disturbance in the testing process, as the impact caused by the elimi- nation of matrix effect, so the analysis of mixed flux melting sample preparation and X ray fluorescence spectrome- try for simuhaneous determination of chlorite rocks slip in the stone of the elements. Not only can be used for the determination of elements in geological samples in talc chlorite rocks type, and short test period, the experimental sample has the advantages of simple process, less material, determination of geochemical samples and samples of different geological samples, comparing the experimental test results were accurate, reliable, and the measurement results of good precision and accuracy high data and chemical analysis results are basically the same, but the ratio of chemical method of low cost, short process, suitable for the analysis of chlorite rocks type in talc major elements.
