西起班公湖,向东大体沿黑(河)阿(里)公路,经改则、尼玛、东巧—那曲,再向东,大体与怒江上游相连接的一条超基性岩带逐渐引起人们的注意。经几次考察,已初步被认为是一条重要的构造界线,甚至可与南面的雅鲁藏布江带相对比。然而,由于过去工作的较少,对该构造带的研究尚很不够。 From west to Bangong Lake, eastward, roughly along the Black River (river) A (road) highway, through the change, Nima, Dongqiao - Nagqu, and then to the east, generally connected with the upstream Nu Nu up gradually attract people’s attention.
