| 中文摘要: |
| 厂洞箐矿区地处西南三江成矿带南段之唐古拉- 昌都- 思茅陆块铜、铅、锌、金成矿带，区内地质构造复杂，火山活动频繁，成矿地质条件较好。火山活动为成矿提供了充足的热源和物源，区域逆冲推覆构造是矿区内含矿流体运移的导矿和容矿空间。厂洞箐铅锌多金属矿为多期次成矿，矿体严格受北北西向断裂构造控制，产于一碗水组上段，为中低温热液充填交代型矿床。本文系统总结分析了厂洞箐矿区地质、地球物理、地球化学及遥感测量成果，以成矿地质条件研究为出发点，以地质、地球物理、地球化学及遥感等手段为依托，综合各类信息进行成矿预测，进而圈定出4 个找矿靶区，为下一步找矿工作提供建议。 |
| 英文摘要: |
| Changdongqing mining area is located in the copper, lead, zinc and gold metallogenic belt of Tanggula-Changdu-Simao continental block in the southern part of the Sanjiang metallogenic belt in southwest China, with complex geological structure, frequent volcanic activity and good ore-forming geological conditions. Volcanic activity provides sufficient heat and material sources for mineralization, and the regional thrust-nappe structure is the ore-conducting and ore-bearing space for the migration of ore-bearing fluids in the area. The Changdongqing lead-zinc polymetallic deposit is a multi-stage metallogenic deposit. The orebody is strictly controlled by the NNW-trending fault structure and occurs in the upper member of the Yiwangshui formation. It is a medium-low temperature hydrothermal filling metasomatism deposit. This paper systematically summarizes and analyzes the geophysical and geochemical telemetry results in Changdongqing mining area, takes the study of ore-forming geological conditions as the starting point, relies on the geophysical and geochemical remote means, synthesizes all kinds of information to carry out metallogenic prediction, and then delineates four ore prospecting targets to provide suggestions for the next step of ore prospecting. |
