哈密地区夹白山韧性剪切带显微构造特征

MICROSTRUCTURE CHARACTERISTICS AND DYNAMIC ANALYSIS OF THE JIABAISHAN DUCTILE SHEAR ZONE,XINJIANG HAMI DISTRICT

哈密夹白山韧性剪切带位于阿其克库都克断裂以北的狭长地带,构成该地区古糜棱岩片.由北向南卷入的地层有石炭系干墩岩组、梧桐窝子岩组和雅满苏岩组,共同构成了北天山区域低温动力变质岩系.从显微尺度的变质变形矿物构造入手,结合地质学、岩石学资料对该地区古糜棱岩片的几何学、力学性质进行了详细分析.

Distributing on the panhandle zone to north of Aqikebulak Fault, Xinjiang Hami Jiabaishan ductile shear zone, which made up of the paleomylonite sections of this area.The metamorphic and distortional stratums immistured into this area from noth to south are Gandun Petrofabric, Wutongwozi Petrofabric, Yamanshu Petrofabric, all of which made up of the regional low teperature dynamic metamorphite series of north Tianshan metamorphic subarea.Starting with microscale metamorphic and distortional minerals and microstructures, and combining with geology data and petrology data, this article had analysed the geometrical and mechanical characteristics of the paleomylonite sections detailedly.
