摘要
野外地质、几何学、运动学及构造应力场的研究表明 ,桂东南那卜韧性剪切带具两期活动性质 :主期变形机制具右行走滑性质 ,而前期变形机制以压扁作用为主。通过野外调研和室内综合分析 ,详细论述了该韧性剪切带的构造样式、岩石组合、显微组构以及韧性变形过程中的岩石转变等 ,并初步探讨了韧性剪切带的应变、形成环境和变形机制。
Field geologic survey and study of geometry, kinematics structural stress field show that the ductile shear zone underwent two stages of deformation: early staving and later dextral strike-slipping. The tectonic style, rock assemblage, microscopic fabric and petrologic transformation are described, and the strain change, deformation environment and deformation mechanism are discussed.
