| 摘 要： | 布托别山金矿带为新疆多拉纳萨依金矿田的西矿带.其构造作用主要经历三期:早期,区域右旋剪切形成一类规模较大的同斜、紧闭、倾竖型褶皱;中期,左旋剪切形成一套由“B”型转换成“A·B”过渡型系列柔性褶皱;晚期,在左旋剪切条件下,产生滑劈理群和微观变形,并叠加于前两期构造之上.构成一条特别醒目的NNW向脆-韧性剪切带。金矿化体严格受这一剪切带控制.

| Abstract: | Mt. Butuobie gold-ore belt is located in the Doulanasaiyi gold-ore field and has underwent three-stages tectonism.
Early stage: A set of large-scale congruous, colosed, plunging vertical folds were formed due to dextral shear stress.
Middle stage: A set of ductile folds in the transition from "B" type to "A,B" type were formed due to the sinistral shear stress.
Late stage: Slip cleavage group and micro-deformation formed in this stage had superposed on the structures produced in the former two stages. A brittle-ductile shear belt that occurred in the research area is resulted from the structural superposition during the three stages. The gold-ore body is controlled by that shear belt. |
