| 摘 要： | 爱林铁矿区内仅发育一条矿体，属小型矿山.矿石类型为磁铁石英岩型，矿体赋存于鞍山群地层捕掳体中，属层控矿床.控矿构造为爱林至蜂蜜沟复背斜，矿体发育于其南翼.由于缺少大规模容矿构造，该矿区不具备成大矿、富矿的构造条件.区域变质及混合岩化作用与该矿床的形成直接相关，尤其是吕梁期混合岩化作用对铁矿的富集和重结晶起到积极作用.矿床成因为典型的沉积变质型，即鞍山式铁矿.

| Abstract: | The Ailin iron deposit,with a single orebody in the orefield,is a small-scale mine.The orebody of magnetite quartzite type occurs in the xenolith of Anshan Group,belonging to strata-bound deposit.The ore-controlling structure is Ailin-Fengmigou anticlinoria,with the orebody developed in the south wing.Due to the lack of large-scale ore-hosting structure,the orefield does not have the structural conditions for large and rich ores.The regional metamorphism and migmatization are directly related to the formation of deposit,and particularly the migmatization in Luliang period plays a positive role in the enrichment and recrystallization of iron ore.The genesis of deposit is typical sedimentary metamorphism,that is,Anshan-type iron deposit. |
