英文摘要Widely distributed siliceous m & eacute;langes in the Yarlung-Tsangpo suture zone preserve significant information of the Neo-Tethys and subduction-accretion processes. Similar ophiolites and siliceous m & eacute;langes are well exposed in the Xigaze and Zedong areas, however, their relationship including age assignments, depositional environments, and accretionary process remains vague. Based on radiolarian biostratigraphy (56 species belonging to 35 genera), black cherts from the Carnian to the Norian (Late Triassic), red cherts from the Aalenian to Bathonian (Middle Jurassic), and siliceous mudstones of the Berriasian (Early Cretaceous) are distinguished from siliceous m & eacute;lange in the Zedong area. Values of Al/(Al + Fe + Mn) indicate that the siliceous rocks are biogenic silica derived. The diagrams of Al2O3/(Al2O3 + Fe2O3) vs Fe2O3/TiO2 and Al2O3/(Al2O3 + Fe2O3) vs La-N/Ce-N indicate siliceous rocks were deposited far from the ridge. Weak positive Ce anomaly and low ratio of La-N/Ce-N indicate that siliceous rocks were deposited in a deep-sea basin proximal to terrigenous sources. Comprehensive summary of studies on Bainang siliceous m & eacute;lange, Xigaze ophiolite, Zedong ophiolite, and Zedong siliceous m & eacute;lange reconstructs the Ocean Plate Stratigraphy (OPS) and the evolution of the Neo-Tethys since the Late Triassic till the Early Cretaceous. M & eacute;langes in Xigaze and Zedong were formed in different intra-oceanic subduction-accretion systems at different times in the Neo-Tethys Ocean during the Cretaceous.
