用化学物相分析法测定某些单矿物的化学组成

Determination of The Chemical Compostion of Minerals by Chemical Phase Analysis

在成因矿物学研究和矿床的物质组成研究中,需要较准确地测定一些单矿物的化学组成。然而,单矿物的纯度,有时却很难满足研究工作的要求,如某些热液矿床产出的金属磁化物矿物,由于成矿时热液快速冷却,晶出嵌布粒度很细的矿物,并与共生矿物形成包果体。

The mineral composition are oi great importance in the study of genetic minerlogy.The main rules are shown in the paper for the accurate determination of the chemical composition of minerals using chemical phase analysis.The examples are described in detail for pyrrhotine,pyrite and pentlandite in ores of a certain nickel deposit.
