Indus-Yarlung suture zone
The Indus-Yarlung suture zone or the Indus-Yarlung Tsangpo suture is a tectonic suture in southern Tibet and across the north margin of the Himalayas which resulted from the collision between the Indian Plate and the Eurasian Plate starting about 52 Ma. The north side of the suture zone is the Ladakh Batholith of the Karakoram-Lhasa Block.
