The Altay North Junggar Cr- Cu- Au- Pb- Zn- Ni metallogenic belt is one of the sixteen major metallogenic belts, which are designated as the national key exploration work. The belt is part of the Altai giant metallogenic belt within China. Based on assessment of national mineral resources and potential, new prospecting theory and advances, authors revised the boundaries of this metallogenic belt. Based on the history of tectonic evolution, this study summarized the regional geological background and its geological conditions, and further revised its metallogenic lineage. Geological features of each metallogenic unit and their corresponding deposit types and typical deposits were also summarized, with an emphasis on assessment of mineral resources. On the basis of previous research data and our results, nine target prospecting areas were defined, among them three are key areas and six are average ones. This work will have important guiding and referential significance to further geological prospecting deployment.
