| 摘 要： | 沂沭断裂是一条纵贯山东的深大断裂带。本文通过对该断裂带断裂构违岩显微变形研究,认为该断裂带在其发展演化过程中经历了塑性变形,塑脆性变形,脆性变形3个阶段。本文主要对其脆性变形阶段进行了研究,认为断裂带在该变形阶段至少经历了6次较为强烈的构造变动,进一步确定了造成这些变动的主压应力方位。

| Abstract: | Yishu fault zone is a large fault which runs through Shandong Province. The micro-structures of the tectonite in Yishu fault zone have been studied. From this study; it is suggested that the development of the fault involved three deformation stages: 1) Plastic flow; 2) Plastic-brittleness deformation; 3) Brittleness deformation. The brittleness deformation in Yishu fault zpne having been continuing in six activities.This study has been used to explored the principal stress direction of these activities. |
