摘要
6056地点是在我国旧石器考古历史上占有重要地位的匼河旧石器遗址群的一个代表性遗址,其年代一直存在较大的争议,主流观点由于将遗址文化层上覆堆积巨厚的黄土层看作是"红色土",而认为文化层属于早更新世晚期或中更新世早期。在对遗址地层分析的基础上,对遗址地层进行了系统的光释光测年,结果表明该层黄土为末次冰期堆积的马兰黄土,结合对文化层的年代测定以及沉积特征的分析,认为该遗址形成年代为末次间冰期晚期,具体年代为8万年左右,这与传统上主流认识存在较大的差别。
Site 6056 is one of the most important representative discoveries of the Kehe paleolithic sites, and plays a very important role in the history of paleolithic archaeology in China; however,its age has been disputed. The mainstream view considers the relic culture belonged to the late period of the early Pleistocene or the early part of the middle Pleistocene, but, based on the analysis on the loess and field observations, we suggest that its age may not be such old and should belong to the late Pleistocene. One reason for the contrast dispute is due to lack of proper dating the cultural layers and the huge loess covering on the relic stratigraphy. In this paper, systematic OSL （optically stimulated luminescence）dating for the relic layers and the huge loess cover is made and the result shows that the age of site 6056 is about 80 ka. This result supports the conclusion based on our analysis of loess susceptibility and the chronology of mammalian lossil, which is greatly different from the traditional view.
