摘　　要：班公湖—怒江结合带构造演化过程与成矿作用密切相关。作为青藏高原一条重要的地质界线,了解其演化历史不仅对于了解整个青藏高原的演化过程具有十分重要的意义,还同时有利于了解其周围同时期元素的富集成矿作用。本文通过研究班—怒带分别在侏罗纪、早白垩世、晚白垩世、古近纪和新近纪四个时间阶段的具体演化过程和成矿作用,发现中、新生代是主要成矿期,其中最重要的是与白垩纪相关的成矿事件,新生代为砂金、盐湖矿形成阶段。The structural evolution of the Bangong Lake-Nujiang junction is closely related to mineralization. As an important geological boundary of the Qinghai-Tibet Plateau, understanding its evolution history is not only of great importance for understanding the evolution process of the entire Tibetan Plateau, but also conducive to understanding the rich and integrated mineralization of the surrounding elements of the same period. This paper studies the specific evolutionary processes and mineralization of the class-anger zone in the Jurassic, Early Cretaceous, Late Cretaceous, Paleogene, and Neogene periods, and finds that the Mesozoic and Cenozoic generations were the main mineralization periods. Among them, the most important are the ore-forming events associated with the Cretaceous, and the Cenozoic was the formation of placer gold and salt lakes.
