EN-US style="FONT-SIZE: 14pt">The Yarlung Tsangpo suture zone in Tibet marks the tectonic boundary between Eurasian and Indian plates and the sedimentary rocks can provide valuable records for the evolution of Neo-Tethys Ocean. During our field work in the summer of 2005 and 2006, The authors examined the Sangdanlin section, which lies in sedimentary mélange of Yarlung Tsangpo suture zone in Gyirong, southern Tibet. The Sangdanlin section consists of the Sangdanlin Formation (Late Cretaceous) and the overlying Zheya Formation (Early Eocene). The Sangdanlin Formation consists mainly of quartzitic sandstone, silty shale and siliceous rocks, sandstones which are comprised of monocrystalline quartz grains with good maturity in both composition and structure, and no volcanic lithoclast was observed.
