摘　　要：雪龙山变质岩原岩的形成时代为前震旦纪,变质程度达中-深变质,为兰坪—思茅陆块的结晶基底;区内有糜棱岩化岩石和初糜棱岩、糜棱岩及超糜棱岩等动力变质岩,变质岩带的韧性变形可以划为4期,即晋宁期、印支-燕山早期、燕山晚期及喜马拉雅期。The original rock of Xuelongshan metamorphic rock series was formed in pre-Sinian Period and moderately-intensely metamorphosed. It is the crystalline basement of Lanping-Simao block. In the study area occur primary mylonite, mylonite and ultra-mylonite. The metamorphic belt can be divided into four ductile deformation phases, i.e. Jinning, Indosinian-Early Yanshanian, Late Yanshanian and Himalayan phases.
