英文摘要	We focus on the upper Cretaceous-Palaeogene terrigenous sequences in the Tethyan Himalaya near the Gyangze and Gamba. Our research presents detrital petrology and geochemistry and Cr-spinel electron microprobe data, which together illustrate significant provenance change at the Paleocene and provide the early history of the basin and orogen belt. The latest Cretaceous Zongzhuo Formation in Gyangze was deposited in trench. The Rilang conglomerates unite is lithic arkose which was derived from transitional arc, and geochemistry shows input of ocean island arc materials. Its provenance is ocean island arc or accretionary prism. Late Paleocene-early Eocene Jiachala Formation is feldspathic indicating a mixing provenance of Gangdese magmatic arc and recyled orogen provenances, which deposited in a foredeep responded the India-Asia collision. The early Paleocene Judula Formation in Gamba is composed of quartz sandstone from interior India. In contrast, the Eocene Zhepure Formation consisting of lithic sandstone is characterized of active continental margin. We propose the development of the Yalu-Zangbo peripheral foreland basin and the onset of India-Asia collision occurred at 65-55 Ma in the central Tethyan Himalaya.
