| 摘 要： | 通过对研究区南迦巴瓦岩群的大比例尺填图工作，根据南迦巴瓦岩群的原岩建造、变质程度的不同、变形样式的差异，将其解体为在区域上具有可填性3套岩石组合——直白岩组、派乡岩组和多雄拉混合岩，三者之间均以构造面接触。

| Abstract: | The Namjagbarwa Group Complex within the Eastern Himalayan syntaxis,Xizang may be sub- divided,on the basis of regional geological mapping in combination with rock types,metamorphic degrees and deformational patterns,into three mappable units: Zhibai and Paixiang Formation Complexes,Doxongla migmatites,all of which are bounded by the structural contacts and surrounded by the Indus-Yarlung Zangbo suture zone. The protolith ages for the Zhibai Formation Complex should be dated between 1312 Ma and 552 Ma. |
