波密-察隅地区位于阿尔卑斯-喜马拉雅特提斯构造域由东西向转为南北向的大拐弯部位,东90°海岭的正北端。区内断裂构造发育,主要有曲拉马-日东,松宗-古琴-嘎达,嘎龙寺-察隅三条北西向断裂和北北西向的夏里-来姑断裂将本区分为几个近似平行四边形的块体,构成了本区的基本构造轮廓,为大规模的岩浆活动提供了有利的构造条件。沿北西向构造线分布有扎西则、德姆拉、阿扎贡拉、察隅四条巨大的复式花岗岩基。其时代由燕
The Bami-Chayu region is located at the corner of the Alps-Himalaya Tethys tectonics from the east-west to the north-south, with the northern end of the east 90 ° ridge. There are mainly fault structures developed in the area, including the three northwesterly faults of the Songla-Ritong, Songzong-Guqin-Gada, Ga Longsi-Chayu and the north-northwest Xiari-Laiu fracture. This area is divided into several similarities The parallelepiped blocks form the basic structural contour of the area and provide advantageous structural conditions for large-scale magmatic activity. Along the northwest tectonic line are distributed Tashi, Deram, Azagorra, Chayu four huge multi-granite base. Its time by Yan
