目前,电子探针分析仪用于分析矿物得到广泛的应用。但对岩石和造岩矿物的定量分析与金属矿物分析相比,有它特殊的困难。主要表现在:(1)岩石分析,是要求得到岩石的平均化学成分,不是某一微区的成分。电子探针分析要使有限的分析区域的化学成分能代表整个取样地质体,就需要解决样品制备问题,还要解决测量方法问题;(2)岩石和造岩矿物均为非导电性物质,因此,分析前样品必须经
Currently, electronic probe analyzers are used to analyze minerals for a wide range of applications. However, the quantitative analysis of rock and rock-forming minerals has its own particular difficulties compared with the analysis of metallogenic minerals. Mainly in: (1) rock analysis, is asking for the average chemical composition of the rock, not a micro-area components. Electron-probe analysis requires that the chemical composition of a limited area of analysis represent the entire sampled geologic body, and that sample-preparation and solution problems must be addressed. (2) Both rock and rock-forming minerals are non-conductive and therefore , The sample before analysis must pass
