The Yarlung Zongbo Suture Zone(YZSZ)is thought to be the most important geological boundary,the collision between the India plate and the Eurasia happened since Cretaceous-Tertiary(Aitchison et al.,2011).The YZSZ,bordered to the north by the Lhasa Block and to the south by the Tethyan sedimentary sequence and the Greater Himalaya,is exposed and dominated by the ophiolite complexes,the ophiolitic mélange,and metamorphic and sedimentary sequences and mélanges reflecting destruction of the Neo-Tethys Ocean.Although the YZSZ has been studied for more than 80 years,several major questions remain unanswered.For example,the timing of the formation of the suture zone and the kinetic processes are still exist hot argument(e.g.Allègre et al.,1984; Aitchison et al.,2000; Ziabrev et al.,2003; Hébert et al.,2012; etc).Documenting the crustal architecture and geochronology of YZSZ is critical to understand the tectonic evolution of Neo-Tethys between the India plate and the Eurasia.
