摘　　要：近年来地质科研工作对单矿物分析提出了新的任务。除主、次元素外,还要求测定微量元素。地质科学工作者已把微量元素研究作为探索矿床成因的主要手段之一。本文继黄铁矿分析之后,试图把等离子体直读光谱分析技术的应用扩大到其他硫化矿单矿物的分析领域。具体实验包括闪锌矿、方铅矿和黄铜矿。The study of trace elements is an important means of research of metalloge-ny, and single minerals now require to be analyzed for trace elements as well as major elements. The sample is dissolved by HNO_(3) and aqua regia. Most trace elements are separated by passing through a resin column. 85%acetone+ 0.5mol·L^(-1) HBr is used as eluant to separate Zn, Ph, Cu for the determination of other eleme is a separate sample is used for the determination of gold.
