| 中文摘要: |
| 西藏班公湖—怒江成矿带是重要的铁铜金多金属成矿带,矿产资源丰富,找矿前景良好。文章以那加木地区为研究区,利用WorldView-2高分影像数据解译结果,通过野外调查验证,新发现了多处沉积岩型铜多金属矿矿化线索。综合矿产地质资料研究分析,定位了竟柱山组为研究区沉积岩型铜矿的赋矿地层,并建立了遥感找矿模型,最后在 GIS平台上,通过找矿模型圈定2处沉积岩型铜矿找矿靶区,为班公湖—怒江成矿带西段那家木地区进一步开展矿产资源调查工作提供了基础资料。 |
| 英文摘要: |
| The Bangong Lake - Nujiang metallogenic belt is an important iron-copper-gold polymetallic metallogenic belt, which is abundant in mineral resources and there is great prospecting potential. In this paper, the Najiamu area in Tibet is taken as the study case. Based on the interpretation result of high resolution remote sensing WorldView-2 data, along with the field investigation and verification, several sedimentary rock type copper polymetallic mineralization occurrences were discovered. Based on integrated analysis of ore-forming geological condition, the Jingzhushan group was defined as the ore-bearing stratum. Then the RS prospecting model is established for the Najiamu area. Finally, two prospecting targets were delineated based on GIS platform. These results provide basic data and scientific basis for the further exploration in the Najiamu area, Tibet. |
