摘要: 西拉木伦断裂带在早二叠世末发生了韧性右行走滑，形成了包括韧性右行走滑带、韧性压扁带及弱韧性变形带在内的韧性变形带。据动力和运动分析，表明该韧性变形带为一普通剪切带，其中韧性右行走滑带在平面上以简单剪切为主，韧性压扁带在平面上以纯剪切为主。
Abstract: Ductile dextral strike slip occurred in the Xar Moron fault zone north of Chifeng,Inner Mongolia,at the end of the Early Permian,forming a ductile deformation zone including the ductile dextral strike slip zone,ductile flaser zone and weak ductile deformation zone.Dynamic and kinetic analyses indicate that the ductile deformation zone is an ordinary shear zone,in which the ductile dextral strike slip zone is mainly of simple shear origin in plan,while the ductile flaser zone is mainly of pure shear origin in plan.
