摘要
山西夏川遗址(35°26′22″N,112°00′43″E)位于山西省北部,是一处重要的旧石器时代中、上层遗址,包含旧石器时代中期文化、旧石器时代初期和上层早期文化、旧石器时代上层中期文化和旧石器时代上层晚期文化四个发展阶段。为了建立该遗址的年代学框架,采用细粒石英的蓝色刺激光致发光(OSL)和细粒多矿物的后红外刺激发光(后红外 IRSL 或 pIR)方法,对 Fuyihegeliang 地点(地点 FYH)QX2017T1 勘测断面的一个地层序列进行了年代测定。上旧石器时代文化层的石英 OSL 年龄在 21.4 ± 1.6 ka 至 42.2 ± 3.0 ka 之间,与校准的 C 年龄一致。中旧石器时代文化层的年代为 118.2 ± 8.5 至 128.3 ± 9.5 ka,采用的是多矿物 pIRIR 方案。这些新结果使我们能够将旧石器时代上层文化层的主要部分归入海洋同位素阶段(MIS)3 的晚期和 MIS 2 的早期,而旧石器时代中层文化层则归入 MIS 5 的早期。在MIS 2和MIS 3以及MIS 5间冰期早期,峡川遗址都出现了早期人类,这反映了他们适应多变环境的能力。
Luminescence chronology of the Xiachuan Paleolithic site in Shanxi Province, northern China: A comparison between OSL and post-IR IRSL ages
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.
