中文摘要:
      蒙古国伊罗河铁矿床属于华力西晚期形成的接触交代型铁矿床,探获资源量近10×108t,矿床平均品位>50%,外围有多个探明铁矿产地及找矿远景区,周边潜在资源量30×108~40×108t。为探讨该区域接触交代型铁矿床的成矿地质规律,本文从伊罗河铁矿的成矿地质背景、矿区地层、构造、岩浆岩、变质作用分析入手,以其东矿段Ⅰ号矿体为例详细论述矿体形态、规模、产状、赋矿岩性特征,通过矿石样品测试分析阐述矿物组成特征、化学成分、矿石结构构造、磁铁矿粒度及成矿阶段等,初步总结了矿床成因和找矿标志。
英文摘要:
      Yiluo River Fe deposit is a Late Variscian deposit with 1 billion tons of Fe ore resources. The average grade is >50% Fe. In surroundings of the deposit there are several Fe ore occurrences and potential areas for further prospecting. with potential mineral resources estimated at 30×108-40×108 tons. In the paper metallogenic background, strata, structure, magmatic rock and metamorphism of the deposit are dealt with to explore its metallogenic law. Morphology, size, occurrence, host rock characteristics of ore body 1 in the east domain, mineralogy, chemical composition, structure and texture, grain size of magnetite of the ore and metallogenic stage of the deposit are detailly described and genesis of the deposit and prospecting marks pointed out.
