| 中文摘要: |
| 中非铜钴成矿带是世界上资源量最大的沉积岩容矿层状铜矿床(SSC)铜钴矿带,卢菲利安(lufulian)弧位于中非铜钴成矿带中部,卡富埃(Kafue)背斜位于卢菲利安弧的东部,该地区矿床的形成均与区域构造密切相关。文章基于Sentinel-2A卫星数据的解译,建立了卡富埃背斜北部地层、构造和岩浆岩的解译标志,特别是对变质核杂岩和主—次级拆离断层进行了解译和分析。研究认为该地区地壳伸展作用下的变质核杂岩和拆离断层构造与成矿过程密切相关,是重要的找矿标志。 |
| 英文摘要: |
| The copper-cobalt metallogenic belt in central Africa is the largest deposit of sedimentary rock bearing stratified copper deposit (SSC) in the world. Lufulian arc is located in the central part of the Copper-cobalt metallogenic belt in central Africa, and Kafue anticline is located in the eastern part of the Lufulian Arc. The formation of deposits in this area is closely related to regional structures. Based on the interpretation of Sentinel-2A satellite data, this paper establishes the interpretation markers for the stratigraphy, structure and magmatic rocks in the northern Cafuai anticline, especially for the interpretation and analysis of metamorphic core complexes and primary and secondary detachment faults. It is considered that metamorphic core complex and detachment fault structure under crustal extension in this area are closely related to the mineralization process and are important prospecting indicators. |
