随着铬铁矿物质成分与成矿规律研究的不断深入,对铬尖晶石类质同象系列矿物的鉴定与研究也越来越深化了.本文通过简便的X射线粉晶分析方法,结合一定的理论计算(结构分析),对铬尖晶石系列矿物的阳离子成分及其位置分布进行研究,以便从矿物学的角度探讨尖晶石类阳离子的迁移与富集规律,为铬铁矿成矿理论研究提供一定的依据. With the deepening of researches on the composition and mineralization rules of chromite, the identification and research on the chromic spinel isomorphic minerals have also been deepened.In this paper, by simple X-ray powder analysis, Some theoretical calculations (structural analysis), the chromium spinel series of minerals cations and their location distribution to study from a mineralogical point of view of spinel cations migration and enrichment rules for the chromite into Mine theory provides some basis for the study.
