摘要
糜棱岩是一种在固态下发生流动和动态重结晶的强烈变形岩石,是韧性变形的产物,其分类应以糜棱岩化基质与碎斑的比例为主要标志。当前,国内外在对糜棱岩的显微构造及宏观特征、变形机制、变形环境、空间展布的研究方面,取得了较大进展,同时也提出了有待深入探讨的新课题。
AbstractMylonite is an intensively deformed rock produced by the solid flowing and dynamical recrystailization in the primary rock or by ductile deformation in general.ItS classification usually should be based chiefly on what is the ratio of the mylonitized matrix to brocken phenocrysts. Recent years in studies of mylonite with respect to its micro-and macrostructures, deformational mechanism, deformation conditions and spatial orientation, cerium prominent advancements have been made but some challenging problems have also risen and need to be solved in the coming years.
