| 摘 要： | 艾肯达坂一带火山机体位于伊犁石炭一二叠纪裂谷阿吾拉勒二叠纪火山岩带东段，在航卫片表现为较明显的环形构造。艾肯达坂火山穹窿构造保留较完整，地层层面和流动构造呈现以次安山岩为中心，向周边倾斜，倾角平缓稳定，大多小于３０℃，火山岩相较完整，集块岩、火山角砾岩、熔岩待发育，火山岩以钙碱性系列为主，形成环境为造山带，时代确定为早二叠世早期。艾肯达坂铜银矿及３个铜矿点均受艾肯达坂火山穹窿的环状断裂和放射断裂及

| Abstract: | Volcanic apparatus at Aiken Daban is located at the eastern part of Awulale Permian volcanic belt. It belongs to Ili Carboniferous-Permian rift, and demonstrated an evident ring structure at the remotesensing pictures. The volcanic dome at Aiken Daban is well preserved, with sub-andesites at the center and calc-alkaline volcanics surrounding it with a gentle dip normally not more than 30 degree. The cafe-alkaline volcanics were formed at early stage of early Permian. The Aiken Deban Cu-Ag mine and three occurences of Cu depoist are all controlled by ring faults and radiating faults of Aiken Daban volcanic dome as well as their intersections. |
