| 摘 要： | 从铁矿储量、品位等数据统计出发，分析各类铁矿品位的分布特点与规律，认为铁矿品位分布结构与该类铁矿的成矿条件，作用特点和机制有关；以系统数据及图表论证了单一成矿作用、一次成矿形成广泛分布的贫矿，再次或多期次（多阶段）和多种作用成矿的同位叠加，是使品位加富和形成工业富铁矿的关键；对各类铁矿品位高低、富矿规模力图进行合理的解释。

| Abstract: | On the basis of statistic analysis of data for the iron ore reserves and grade in the paper,it are studied that is the distributing characters and laws of ore grade for each type iron ore deposits,and the authors are sure that the distributing structure of the ore grade for each type iron deposits is relaied to the condition. the character and the mechanism of iron metallogenesis. According to a succession of the statistic data and the diagram, it are demonstrated,that the single and once iron metallogenesis leads to the poor iron ore disiributed wibely, that the superimposition of twice or many epoch (much stage) and polytypic metallogenesis at same place is key factory of the ore grade richening and the metallogenesis of the rich iron ore. It is attempt reasonably to explain why the iron ore grade is heightened/lowered and the size of rich iron deposits is varied. |
