喜马拉雅山脉东西两端遥相对应的南迦巴瓦峰(7756米)和南迦帕尔巴特(Nanga-parbat 8125米)分别位于雅鲁藏布江和印度河大转弯的内侧,并分别组成“缅甸弧”和“结罗姆弧”的核心,但是二者实际上可能并不是真正相等的。至少就雅鲁藏布下游地区来说事实上并不存在一个真正的弧弯,而是一个比简单的弧弯要复杂得多的构造区。 The Namjagbarwa (7,756 m) and Nanga-parbat (8,125 m) Nonga-parbat at the east and west ends of the Himalayas are located on the inner sides of the great turns of the Brahmaputra and the Indus respectively and form the “Burma Arc” and The core of the “knot Roma arc,” but the two may not actually be exactly equal. At least for the lower reaches of the Brahmaputra, there is virtually no real arc, but a much more complicated zone than a simple arc.
