| 中文摘要: |
| 文章以那西郭勒铁矿床为例,在深入剖析该铁矿床成矿地质背景及成因的基础上,基于WorldView-2遥感数据解译了赋矿地层及含矿岩性,总结了地层、含矿岩性及铁矿带遥感影像特征,同时分析该矿床遥感蚀变异常特征,结合构造、磁异常等找矿信息,构建了沉积—变质型铁矿遥感综合找矿模式；通过该找矿模式预测了1处找矿有利地段,为该地区的后续基础地质、矿产勘查工作,以及关键地段的含矿性或找矿潜力评价提供参考依据。 |
| 英文摘要: |
| Taking Naxiguole sedimentary metamorphic type iron deposit as a case study for the purpose of establishing comprehensive remote sensing prospecting model. On the basis of studying metallogenic geological setting and deposit genesis, the ore-bearing strata and lithological units of Naxiguole iron deposit were interpreted by using WorldView-2 and ETM remote sensing data, and the remote sensing image features of ore-bearing strata, lithological units and iron ore belt were summarized. Meanwhile remote sensing alteration anomalous features were analyzed. In combination with ore-controlling structures and magnetic anomalies information, the comprehensive remote sensing prospecting model for the sedimentary metamorphic iron deposit was constructed. Based on the model, one favorable prospecting area was delineated which can be serve as follow-up prospecting target as well as provides relative reference for assessment of key ore-bearing mineralization zone and prospection potential. |
