Abstract: Sixty years ago, Pei Wenzhong (W. c. Pei) discovered the first skull of Peking Man inthe 1lth layer, Loc. 1, Zhoukoudian, Beijing (1929). However, the actual age of its burying isstill not sure up to now. In this paper, the deer fossil teeth are collected from the 3--4, 8--9and 11 layers in Loc.1. The accumulative dosés and internal annual doses of fossil teeth ( ena-mel) have been gotten by electron spin resonance spectrometer (ESR) and neutron activationanalysis. The environmental annual doses have been obtained by thermoluminescene dosime-ters to be embedded in the 2nd layer to the 12th layer of the site. The linear uraniumuptake :model is adopted to calculate the ESR ages of fossil teeth. ESR datingresults showthat theburying age of the first skull of Peking Man is 578ka. Other burying ages of Peking Manin the 3--4th layer and the 8--9th layer are 282 ka and 418ka, respectively. According to thedating results of ESR, ET, TL,U-series and paleomagnetic stratigraphicalmeasurenent, aprimary chronological scale of the deposits of Peking Man Cave is proposed in this paper.
