| 释义 |
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.[1] The north side of the suture zone is the Ladakh Batholith of the Karakoram-Lhasa Block. The rocks of the suture zone consist of an ophiolite mélanges composed of Neotethys oceanic crustal flyschs and ophiolites; the Dras Volcanics: which are basalts, dacites and minor radiolarian cherts - the remains of a mid to late Mesozoic volcanic island arc; and the Indus Molasse which are an Eocene or later continental clastic sediments.[2] The Ophiolith which can be found here is not a remnant of a very big ocean, but of a small so called Back-arc basin structure.[3] See also
