Abstract The Tibetan Plateau is one of the last areas populated by modern humans because of its harsh environment. Due to the paucity of reliably dated archaeological sites, the history of the peopling of Tibet is unclear. However, more than 110 microblade sites discovered on the Plateau indicate large-scale migration. This paper reviews microblade assemblages in seven geographical regions in terms of the specific techno-typologies, and divides them into three types. Based upon results obtained from 17 archaeological sites and techno-typological comparisons, we argue that microblade sites on the Plateau fall within three periods, 14-10 ka BP, 8-7 ka BP and 5-3 ka BP. The techno-typology of sites in the first period is still unclear. Assemblages are dominated by flake blank exploitation cores represented by wedge-shaped nuclei during the second period. Conical microblade cores and pottery coexisted during the latest period. A combination of chronology, techno-typology and the locations of microblade sites discovered on and around the Tibetan Plateau supports the conclusion that people bearing microblade technology originating in North China migrated to the Plateau via a northern route.
