| 摘 要： | 黄山韧性剪切带位于东天山秋格明塔什-黄山韧性剪切带东部,是东天山地区最重要地质构造之一.分析其在黄山东一带表现出的构造形迹,并对该区构造变形期次作初步探讨.黄山韧性剪切带在黄山东一带构造形迹总体显示右旋剪切特征,后期存在左旋剪切,变形期次共4期,剪切应变值为2.4～0.73,有限应变分析认为,变形机制以压扁变形为主.

| Abstract: | Huanghshan ductile shear belt is main structure of East Tianshan Mountains which belong to the eastern part of Mingtashi-huangshan mountain ductile shear belt of East Tianshan Mountain.This paper point out Huanghshan ductile shear belt’s structural feature is right-lateral shear and left-lateral shear at the same time,reflect it’s stress direction had occurred significantly altered.It had four deformation stages,the fourth stage mainly to lefe-lateral shear.Limited strain analysis reflect it’s deformation mechanism is flattening deformation. |
