地质人员在研究锡石单矿物时,不仅需要知道该矿物的主要,次要成分,而且还需查明赋存元素以及与锡矿床成因类型有关的某些特征元素.用化学方法分析锡石单矿物不仅分解样品比较困难,而且其中一些元素的测定灵敏度也难于达到.需用的矿物量也较多.而发射 Geological personnel in the study of Cassiterite single mineral, not only need to know the main and minor components of the mineral, but also need to identify the occurrence of elements and the type of tin deposits related to some of the characteristic elements.Calcium chemical analysis of single It is not only difficult for minerals to decompose samples, but also the sensitivity of some of them is difficult to achieve, and the amount of minerals needed is more.
