摘　　要：为明确内蒙古某矿床不同铁矿石类型与稀土矿化特征的关系,基于矿区内海量、系统的勘查工程所揭露的岩/矿石类型以及稀土、铁的基本分析数据,在已有的铁矿石分类基础上,进一步对铁和稀土资源进行分类。共划分出6种不同类型的铁-稀土矿石类型,并对各类型中稀土的成矿规模、强度及其在空间上的分布特征进行刻画。研究表明,不同类型的铁矿石中稀土成矿性和富集强度存在较大差异,稀土在浅部成矿富集规模大于深部;稀土与铁的矿化在空间产出上存在一定的相关性,但并非同体系流体成矿作用形成。In order to clarify the relationship between different iron ore types and rare earth mineralization characteristics of a deposit in Inner Mongolia,based on the basic analysis data of rock/ore types and rare earth and iron exposed by massive and systematic exploration projects in the mining area,the iron and rare earth resources are further classified on the basis of the existing iron ore classification.A total of 6 different types of iron-rare earth ore types were divided,and the metallogenic scale,intensity and spatial distribution characteristics of rare earth in each type were characterized.Studies have shown that there are great differences in rare earth mineralization and enrichment intensity in different types of iron ores,and the scale of rare earth mineralization and enrichment in the shallow part is greater than that in the deep part.There is a certain correlation between rare earth and iron mineralization in spatial output,but it is not formed by fluid mineralization in the same system.
