Based on field observations in the years of 1973-1974 and other available data, the rocks exposed in the Lower Yalu-Tsangpo River region may be divided into two parts. The Lower, named the Miri group, consists mainly of Paleozoic metamorphosed sedimento-volcanic series; the Upper, named the Namche Bava group, comprises highly metamorphosed and strongly deformed basic volcanics, clastic rocks and a minor part of carbonatites. Faults trending northeast are well developed and intensely compressed. It is assumed that the metamorphism and deformation of the rocks in this region was caused by the northward drift and the subsequent tremendous collision of the Indian plate against the Eurasian plate.The eastern border of the area considered is discussed somewhat in detail. The "Yalu Tsangpo suture", well exposed further west, can be traced eastwards only to the west of the hair pin bend within a fracture zone. Then it reappears along the east side of the Yalu Tsangpo Valley and extends toward southeast down to the eastern slope of Mt. Arakan Yoma, Burma. Along the suture zone, the main rock type is ophiolite, but in the Pakistani Himalaya and on the eastern side of the Yalu Tsangpo Valley it is represented by the "hornblende complex." The relations that the Yalu Tsangpo River bears in its evolution with the geological structures of the region and that between their formation and the northward drifting of the Indian plate are also discussed.
