Abstract
The Xiachuan site (35°26′22″N, 112°00′43″E) in Shanxi Province, northern China is an important Middle and Upper Paleolithic site, which contains four stages of development: the Middle Paleolithic culture, the initial and early Upper Paleolithic culture, the middle Upper Paleolithic culture and the late Upper Paleolithic culture. To establish the chronology framework for the site, a pedo-stratigraphic sequence at the QX2017T1 survey section of Fuyihegeliang Locality (Loc. FYH) was dated using blue-stimulated optically stimulated luminescence (OSL) on fine-grained quartz and post-infrared infrared stimulated luminescence (post-IR IRSL or pIRIR) on fine-grained polymineral. The quartz OSL ages of the Upper Paleolithic culture layer are between 21.4 ± 1.6 and 42.2 ± 3.0 ka, which is consistent with the calibrated 14C ages. The Middle Paleolithic culture layer is dated to from 118.2 ± 8.5 to 128.3 ± 9.5 ka using the polymineral pIRIR100, 290 protocol. These new results allow us to put the main part of the Upper Paleolithic culture layer in the late Marine Isotope Stage (MIS) 3 and the early MIS 2, with the Middle Paleolithic culture layer corresponding to the early MIS 5. A gap of nearly 70 ka is observed between the two cultural layers, which is larger than previously expected. The presence of early hominins in the Xiachuan site during MIS 2 and MIS 3 as well as in early interglacial MIS 5 reflects their ability of adapting to variable environments.
期刊介绍:
Quaternary International is the official journal of the International Union for Quaternary Research. The objectives are to publish a high quality scientific journal under the auspices of the premier Quaternary association that reflects the interdisciplinary nature of INQUA and records recent advances in Quaternary science that appeal to a wide audience.
This series will encompass all the full spectrum of the physical and natural sciences that are commonly employed in solving Quaternary problems. The policy is to publish peer refereed collected research papers from symposia, workshops and meetings sponsored by INQUA. In addition, other organizations may request publication of their collected works pertaining to the Quaternary.
