| 摘 要： | 阿尔泰古火山构造盆地的形成、演化和改造，经历了山前拉张断陷→右型走滑作用产生左型雁列割裂型盆地→冲断－推覆改造的过程。其间，呈分散状态存在于细碧－角斑岩建造内的铜多金属矿质在热动力作用下发生了向矿区迁移聚集的成矿活动。

THE EVOLUTION AND FORMATION OF THE LEFT ECHELON VOLCANIC-SEDIMENTARY BASINS IN ALTAI AND THE TRACING OF THEIR METALLOGENIC ACTIVITIES |
| |
| Abstract: | The formation,evolution, and rework of the paleotectonic basins in the Altai experienced 3 stages:the rifting caused by foreland extension, the forming of left echelon fault-segmented basins by right-handed striking,and the reworking and superimposing by thrusts and nappes.Meanwhile,the dispersed ore-forming material of copper-polymetals in The spilite-keratophyre formation was migrated and enriched at the mine area through thermal dynamical action. |
