Abstract: Metallogenic unit is a geological unit on the metallogenic significance. The latest classification scheme about Chinese metallogenic units released by the national mineral resource potential assessment project include level Ⅰ (metallogenic domain), level Ⅱ (metallogenic provinces) and level Ⅲ (metallogenic belts). This article revises the boundaries of the six level Ⅲ metallogenic units (metallogenic belts) in the East Tianshan-Beishan area on the basis of the inheritance of this classification scheme. Then the six level Ⅲ metallogenic units are divided into 11 class Ⅳ metallogenic units (metallogenic sub-zone)as a symbol of sgnificant stratigraphic, tectonic and magmatic belt and associated mineralization. Furthermore, there is a summary about geology and mineral characteristics of every class Ⅳ metallogenic unit (metallogenic subzones).
