对四套具不同特点的方解石质原岩断层构造岩应用光学显微镜、透射电子显微镜和阴极发光显微镜开展了系统研究。它们都表现出相似的变形显微构造特点与变形作用,宏观碎裂结构与微观糜棱状结构。碎屑颗粒或者变形的原岩颗粒具有发育的晶内变形显微构造(变形双晶、扭折和微破裂等),基质颗粒为弥散的极细粒物质。透射电镜下的微构造表现为反映脆性变形与晶质塑性变形共存的位错
Four sets of calcite protoliths with different characteristics were systematically studied by light microscopy, transmission electron microscopy and cathodoluminescence microscopy. They all show similar deformation microstructural features and deformations, macroscopically fractured structures and microscopic mylonitic structures. Detrital particles or deformed protoliths have developed intragranular deformation microstructures (deformable twins, kinks, micro-cracks, etc.), and the matrix particles are dispersed finely particulate matter. The microstructures under TEM show the dislocations that reflect the coexistence of brittle and crystalline plastic deformation
