摘　　要：双泉金矿床位于新疆东准噶尔地区重要的金及多金属成矿带——卡拉麦里成矿带,产于含金丰度值较高的下石炭统南明水组浅变质岩系中;区内岩浆活动频繁,侵入岩呈岩基状分布于矿区北部;构造十分发育,清水—苏吉泉大断裂斜穿全区,其主断裂及次级断裂构成控矿构造和容矿空间,断裂带内岩石塑性变形明显,发育强烈片理化、糜棱岩化,具韧—脆性剪切变形特征;金矿床类型属破碎蚀变岩夹石英脉型,富集不均匀;金主要来自地层,少量来自深部。The Shuangquan gold deposit, located in the Kalamaili metallogenic zone, is the important gold-polymetal metallogenic zone of East Junggar, and it occurres in the epimetamorphic ore series of Nanmingshui formation of lower carboniferous, which has higher gold abundance. There are frequent magrnatic activity in this area and the incursion rock occurred in the north area as batholith. The Qingshui-Sujiquan falt and its subsidiary fracture were the ore-controlling structure and ore-host space. Rocks in fracture zone had obvious plastic deformation and strong schistosity, mylonitization and had the character of ductile-brittle shear deformation. The Shuangquan gold deposit belongs to the crushing alteration bearing gold-quartzvein type. Au element mainly from stratum, partly from deep source.
