藏南一系列大小不等的穹状隆起的变质核杂岩体，是由前震旦系亚堆扎拉岩群组成内核，古生界曲德贡岩群组成滑脱系，上三叠统郎杰学群和涅如群组成盖层。藏南变质核杂岩划分为多层式、双层式和隐伏式３种类型，是喜马拉雅板片和冈底斯——念青唐古拉板片碰合期后陆内调整阶段由于地壳伸展、深部物质上隆和多层次滑脱剥离作用形成的大陆伸展构造形式，具有重要地质构造意义和成矿控矿作用
In southern Tibet, a series of dome-shaped metamorphic nuclear complex bodies of different sizes are formed by the core of the former Sinian sub-stack Zala group and the Quaternary Quedong group of the Paleozoic. The Upper Triassic Langjie Xue group and Nirvana group cover. The South Tibetan metamorphic core complex is divided into three types: multi-layer, double-layer and invisible. The Himalayan and the Gangdese-Nyainqentanglha plates are in the intracontinental adjustment stage after the engagement period. Due to the extension of the crust, The continental extension structure formed by material uplift and multi-level slippage and detachment has important significance of geological structure and mineralization and ore control
