With the implementation of geological survey and continuous emergence of prospecting and assessment results, Bangong- Nujiang, as one of the most important areas for key to exploration target, is of big importance to conduct systematic metallogenic study and research deployment. Based on the latest prospecting progress and assessment results, this study defined the boundaries of the re- divided metallogenic belt and named it the Bangong- Nujiang Cu- Au- Fe- Li Metallogenic belt. Comprehensive study of the regional geological background divided the working area into three metallogenic zones. The metallogenic system of the Bangong Nujiang polymetallic mineralization belt was established. The study shows that the system is characterized with multiple mineralization stages, with Himalayanian and Yanshanian being the major metallogenic time.The mineralization types in this area include porphyry- type Cu- Au ore deposits, skarn type Cu- Au ore deposits, vein type Au deposits within metamorphic clastic rocks, skarn- type iron ore deposit, modern salt lake type potassium, boron, lithium ore deposits and others. Combined with the latest prospecting and assessment results for this area, this paper suggests that this area is of big potential for Cu, Au, Fe, Li, K and B, which will be working direction for next major mineral species. 13 prospective areas were defined, including two key prospective areas and one average area. This will be of some guiding significance for next mineral exploration and working deployment.
