| 中文摘要: |
| 新疆阿克陶县苏巴什一带具有优越的成矿地质条件,带内相继发现了多个铁矿床,并具有一定的空间连续性。本文通过总结对比带内不同铁矿床的地质特征、赋矿地层、构造变质变形等特征，并以带内典型的磁铁矿床为例，深入分析矿体地质特征、矿体形态、矿物组合及矿石结构构造特征，认为该地区的磁铁矿具有相似的矿床成因及成矿演化史，经历了原始沉积期、区域变质改造期和热液叠加改造期3个阶段，属于沉积变质型磁铁矿。通过物探磁测，明确了区内磁异常主要由磁铁矿（化）引起，并总结了带内磁铁矿找矿标志，为该区铁矿进一步勘探调查指明方向。 |
| 英文摘要: |
| Based on orebody shape characteristics, ore structure and mineral composition, we analyze geological features and genesis of the Subashi magnetite deposit in the West Kunlun Mountains. We suggest that the mineralization process of this deposit could be divided into three stages: primary sedimentary stage (stageⅠ), regional metamorphism stage (stage Ⅱ), and hydrothermal superimposition stage (stage Ⅲ), belonging to the sedimentary metamorphic type. The magnetic survey indicates that the magnetic anomalies in this area are mainly caused by magnetite. Several hidden anomalous bodies are determined as the targets for future exploration． |
