Luminescence dating of Youfangbei early late Pleistocene site, Nihewan Basin, North China
Published online by Cambridge University Press: 12 May 2021
Abstract
Sites dated to the early late Pleistocene are still limited in North China, which has hindered the detailed analysis of the development of Paleolithic industries in the late Pleistocene in this area. The Youfangbei (YFB) site is a newly excavated small-flake-tool Paleolithic site near the Youfang (YF) microblade site in the Nihewan Basin, North China. Because the small-flake-tool industry still existed in the late part of the late Pleistocene and might be related to the emergence of microlithic industries, the relationship between the two sites needs to be determined through a chronological study. Two profiles were excavated, and most of the artifact assemblages were unearthed in the lower profile (T1) from a depth of 0.9 m from the bottom. In this study, the feldspar post-infrared infrared stimulated luminescence method was applied to determine the age of the YFB site. Results showed that the upper profile was deposited from 86–0.5 ka, and the cultural layer in T1 yielded age of 124–82 ka, corresponding to Marine Isotope Stage (MIS) 5, with an irregular but generally mild climate. The age of the YFB site is too old to be directly related to that of the YF site, but it partly bridges a chronological gap of human occupation in the Nihewan Basin.
