Abstract The middle and west part of the Bangong Lake-Nujiang River metallogenic belt is divided in 4 subzones including Tanggula, southern Qiangtang, Bangong Lake-Nujiang River suture and Aanglonggangri-Bangor subzones, which contains 8 major mineralization prospects. The major achievements from recent years’ geological survey on this belt are the understanding of arc-related metallogenesis and ore prospecting progress based on this understanding. Although the Zhapu-Duobuza magmatic arc in the southern margin of the Qiangtang subzone is not a widespread and continuous magmatic belt, significant exploration progress has been made in the Duobuza-Qingcaoshan and Caima-Fuye prospects. A series of mineral deposits and occurrences have been spotted after identifying the Duolong super-large copper deposit, such as Qingcaoshan, Longrong, Bagong and Fuye. In these 4 prospects of the Aanglonggangri-Bangor magmatic arc, besides the identified Gaerqiong and Galale large gold and copper deposits, more mineral deposits and occurrences have been found in Yazhuo, Xiongmei, Shesuo, Kuga, Changgei, etc. The middle and west part of the Bangong Lake-Nujiang River metallogenic belt has shown a great prospecting potential, but there are relevant major geological problems to be solved.
