| 摘 要： | 通过沂沭断裂带内晚元古代至古生代益层变形的详细研究，发现这套盖层遭受了明显的顺层左旋走滑剪切变形。这期盖层变形是与沂沭断裂带基底中北北东走向左行韧性剪切带同期形成的。它们是郯庐断裂带中生代大规模左行平移运动在不同层次上所造成的不同产物。这套益层的变形及其特征证明了郯庐断裂带大平移发生在中生代。

| Abstract: | After detailed research on deformation of the late proterozoic to Paleozoic cover in the Yishu fault zone,the authors found that the cover experienced obviousbedding-parallel sinistral strike-slip shear deformation.This cover deformation wasdeveloped at the same time as the NNE-striking sinistral ductile shear zones in thebasement Of Yishu fault zone.Both the cover deformation and the basement deformationrepresent the products of different levels produced by large scale sinistral strike-slipmovement of Tanlu fault in Mesozoic.The cover deformation indicates that the largescale strike-slip along Tanlu fault zone took place during Mesozoic. |
