沂水北部沂沭断裂带构造透镜体特征

通过对沂水北部沂沐断裂带中段构造透镜作进行几何学、运动学和动力学的研究，指出透镜体多呈对称型展布，并具有分带性的特点。根据透镜体的不对称性、排列方式等特征，对断层的力学性质和运动方向进行判断，认为断裂带内次一级断层的性质和活动方式均具多样的特点，而纯挤压应力和扭压应力作用下形成的构造透镜体则具有不同的特征。

CHARACTERISTICS OF TECTONIC LENSES IN THE NORTH YISHUI AREA OF THE YISHUI FAULT ZONE

In this peper, by stodyting the geometry, dynamics and kinematics of the tectonic lenses in the midde part of the Yishu fault zone, the author points out that the lenses are commonly distributed symetrically and in zonation,The sehistosity zone is the result of further compression and grinding. According to the Lenses asymmetrical distribution pattern and their relationship with the adjacent fault, the author can determine the mechanical property and the sense of movement of the fault. It is concluded that...
