| Abstract: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 metallogenic belts and several prospect areas. The relations between the regional geological evolution and the ore-forming process might be summed up as follows: ① the closing stage of the oceanic crust mainly formed the auriferous source beds ; ② at the collision and orogenic stage, the skarn type and porphyry type ore deposits were formed in the orogenic belts; ③ at the rifting trench stage, the copper-nickel sulfide deposits were formed mainly in Kalatongk; ④ the major gold deposits formed at the continental crust evolution stage include hydrothermal deposits related to metamorphic rocks, epithermal deposits and magmatic hydrothermal deposits related to dioritoids. |
