摘要
武平七里—永平韧性剪切带位于福建省南西 ,为走滑型韧性剪切带 ,主要活动于印支期。通过对剪切带中岩石变形的几何学、运动学特征的研究 ,探讨了其形成的动力学背景 ,认为与南平—宁化构造岩浆带有关 ,是闽西南地块与闽西北地块碰撞形成的低序次的走滑型韧性剪切带。
The Qili Yongping ductile shear zone, located in the southwestern part of Fujian Province, belongs to the strike slip typed ductile shear belt, which occurred in Indo Chinese epoch By analyzing the deformational geometric and dynamic characteristics of the rocks in the shear zones and discussing the dynamic background of the their formation, it is considered that the Qili Yongping ductile shear zone has relation to the Nanping Ninghua tectonomagmatic belt and is the low order strike slip ductile shear zone formed by the collision of the Western Fujian Massif and the Northwestern Fujian Massif.
