Abstract

Abstract:

The Hanjiang River Valley have abundant Paleolithic sites. The coexistence of the cobble-tool and the small flake-tool industriesis of considerable significance for the study of the exchange and integration of the Paleolithic industry between North and South China. Field surveys carried out along the Hanjiang River Valley in the summers of 2016-2018 and revealed 10 Paleolithic sites in the late Pleistocene. Thermally transferred optically stimulated luminescence (TT-OSL) is used to date samples from each site. According to the dating results, the hominin activities in these sites mainly occurred between 200-50 kaBP, covering three stages of L₂, S₁, and L₁. Findings are basically consistent with the previous Paleolithic assemblages found in the second terrace of the Hanjiang River Valley. The study of these 10 Paleolithic sites enriches data of Paleolithic chronology, technology, and human activities in the southern Qinling Mountains, Central China.

Key words: Qinling Mountains, Hanjiang River Valley, Paleolithic, Second terrace, TT-OSL
