摘　　要：位于政和—大埔断裂带中北段的后坪—大洛韧性剪切带 ,规模较大 ,由一系列北北东向平行状、网结状的糜棱岩带组成。是由加里东期和印支期四套运动学性质各不相同的韧性剪切系统构成 ,是不同期次、不同形变叠加变形的产物 。The Houping-Daluo ductile shear belt, located in the northern segment of the Zhenghe-Dapu Deep Fault and with a larger scale, is made up of a series of north-northeastern parallel and anastonmose mylonite zones and is composed of different ductile shear systems of Caledonian and Indo-China epochs.It results from different stages and deformed phases of superposition and deformation and is the product of complex tectonic movements in the middle and shallow layers of orogenic belts.
