碳酸盐类矿物的物相分析对研究与碳酸盐矿物有关的矿床成矿规律中极为重要。本文讨论了方解石族碳酸盐矿物中钙、镁和铁的碳酸盐矿物相分析的化学分析法。根据碳酸盐矿物有一定的组成:利用不同的碳酸盐矿物溶解性能的差别和在一定条件下被溶下的钙、镁和铁(Ⅱ)量的比例关系,判断是类质同象系还是独立矿物并确定类质同象矿物中各原子间的比例关系,可以测定较为富集的碳酸盐矿物中的方解石、白云石、镁铁白云石、菱铁矿、菱镁矿和菱镁菱铁矿系列等矿物物量。方法简易、快速,曾与X射线分析互为对照,结果基本一致。
The phase analysis of carbonate minerals is of great importance in the study of mineralization related to carbonate minerals. This article discusses the chemical analysis of the carbonate mineral phase analysis of calcium, magnesium and iron in calcite carbonate minerals. According to the carbonate minerals have a certain composition: the use of different dissolution characteristics of carbonate minerals and dissolved under certain conditions under the ratio of calcium, magnesium and iron (Ⅱ) the amount of proportion, to determine the isotype system Or as a standalone mineral and determining the proportionality of the atoms in the isomorphic mineral type, it is possible to determine the calcite, dolomite, mafic dolomite, siderite, magnesite and magnesite in the more enriched carbonate minerals Siderite series such as the amount of minerals. The method is simple, rapid, and X-ray analysis with each other, the results are basically the same.
