对四川泸定韧性剪切带红军楼剖面内部结构、变形变质特征研究表明,该剪切带形成于地壳深部,高温高压环境下形成的韧性剪切带,起始于晋宁期,澄江期已具雏形,印支一燕山期受EW挤压,产生逆冲推覆叠加脆性变形。通过对剪切带运动学的分析.结合其几何特征,认为该剪切带为平移一正断层;通过动力学分析,认为韧性剪切带是在近于垂直剪切带走向方向的拉伸应力的作用下.岩石经强烈韧性剪切变形而形成。
A study of deformation and metamorphism in the Hongjunlou section indicates that the Luding ductile shear zone was formed in deep crust during the Jinning-Chengjiang period and superimposed by brittle deformation due to horizontal compression during the Indo-Chinese- Yanshanian period. Kinematical analysis shows the shear zone is a strike-slip fault, while dynamic analysis shows the ductile zone was formed by extensional stress perpendicular to the strike of the ductile zone.
