摘　　要：依据含矿围岩性质，把东准噶尔不同铜金矿床划分为５个主要类型。在较详细地剖析了各主要类型矿床的成矿地质特征的基础上，划分了成矿带和成矿远景区，讨论了区域地质演化与铜金矿床成矿作用的关系。Based on characteristics of ore-bearing wall rocks,the author has classified the copper-gold deposits of east Junggar into five types and also divided this region into three metallo-genic belts and several prospect areas. The relations between the regional geological evolutionand the ore- forming process might be summed up as follows :①the closing stage of theoceanic crust mainly formed the auriferous source beds;②at the collision and orogenic stage,the skarn type and porphyry type ore deposits were formed in the orogenic belts;③at therifting trench stage, the copper-nickel sulfide deposits were formed mainly in Kalatongk ;④the major gold deposits formed at the continental crust evolution stage include hydrothermaldeposits related to metamorphic rocks, epithermal depsoits and magmatic hydrothermal de-posits related to dioritoids.
