| 摘 要： | 在东昆仑中带，北西向韧性剪切带构成了区域构造格局的主要组成部分。以石灰沟韧性剪切带为代表，该类剪切带具有切割深度大、区域延伸稳定的特点，控岩控矿作用明显，并对北西向构造分区有控制作用，其形成演化与东昆仑区域构造发展背景相一致，反映了加里东到印支期，由拉张到挤压、再到走滑扭动的区域构造应力变化。

| Abstract: | The NW SE ductile shear zones are the main part of the regional tectonic framework in the east of Kunlun Mountains. Taking the Shihuigou shear zone as an example , this shear zone has the characteristics of deep dissection and stable stretch. It not only controls the distribution of magmatic rocks and gold deposits, but also controls the stretch of other NW SE structures. Its evolution is in harmony with the changing of tectonic setting in the east of Kunlun Mountains. Its deformation shows that the regional stress state is not the same in different periods and displays stretching in early Paleozoic, compressing in late Paleozoic and twisting in Mesozoic. |
