摘要
作为武当山大型推覆体内部紫金断片构造边界的紫金韧性剪切带具有复合性质,曾先后经历了自北而南的韧性推覆—北东向脆、韧性左行走滑—北东向韧、脆性右行走滑—脆性张破裂及平移。韧性剪切带的演化与武当山推覆构造的递进变形密切相关。
Zijin ductile shear zone in Wudang Mountain nappe structure is a compound one. It is revealed that the shear zone was formaed by three generations of deformation. Ductile thrust from N to S-brittle-ductile sinistral strike slip-ductile-brittle dextral strike slip. They are closely related with development of Zijin mountain nappe structure.
