| 摘 要： | 在详细的野外地质填图的基础上,通过各种尺度的构造研究和系统的应变测量,确定了胶南隆起北缘中段的大型左行正滑韧性剪切带的存在及其延展范围,并提出了确定韧性剪切带边界的构造几何学准则。研究了该韧性剪切带的几何学和运动学特征及变形机制,估算了其剪切位移量(大于7557m)及形成时的差异应力(σ_1-σ_3=94.6～114.4MPa)。该韧性剪切带可以作为胶南隆起的北部边界,但不是重要的板块碰撞边界。

| Abstract: | Based on the detailed field regional geological mapping and research of microscopic
structures, as well as systernatic strain measurement of deformed mineral, a large-scale
left-lateral normal slip ductile shear zone in the north margin of Jiaonan uplift is delimited.
The structural geometric criterion is provided to ascertain the edge of the ductile shear
zone. The geometric. kinematic features and deformation mechanism of the ductile shear
zone are clarified. and the estimate for the displacement of the ductile shear zone (more
than 7 557 m) and the volume of the paleo-differential stress (94. 6～ 114. 4 MPa) are
made. It is reasonable to infer that the left-lateral normal slip ductile shear zone extending
along the margin of the Jiaonan uplift is not an important plate collision zone. |
