摘要
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. This result supports the conclusion based on our analysis of loess susceptibility and the chronology of mammalian fossil, which is greatly different from the traditional view.
