Abstract

Abstract:

Qijiaojing is the earliest discovered microblade site in Xinjiang, which is located in the northwestern part of Hami, at an intermountain basin south to the piedmont of eastern Tianshan. The survey in 2019 recovered an in situ locality with well-preserved living surface and 847 lithic artefacts, which were dated to about 11 ka by OSL. Lithic analysis suggested that bladelets and microblades were made with fine-grained flint, and the assemblage was mostly composed of by-products and debris, while tools were only slightly retouched, indicating that the locality was a short-term lithic workshop. This discovery provided important materials on the adaptation strategy of Arid Asia and cultural exchange between the east and the west during terminal Pleistocene and initial Holocene.

Key words: Qijiaojing site, Microblade, Xinjiang, Open-air site, Pleistocene, Holocene
