Abstract: Based on the carbon-14 dates, this article illustrates the dates o￡ ten late paleolithic si_x001F_tes in China. It points out that different age indicated by the carbon-14 dates of the upper and lower layers of cave deposits has provided definite evidence for the periodization of the late paleolithic culture. It is felt that the abnormal phenomena in the carbon-14 dates for open sites mean a confusion which occurred in secondary deposits caused by deluvium or alluvium. Therefore, the dates available require a further analysis. It is concluded that carbon- 14 dating is a necessary means in the study of the late paleolithic culture, but attention should be paid to the position of the layer and the state of preservation of the samples taken. It is also suggested that scattered charcoalcinders should be avoided as samples and individual carbon-14 dates should be tackled carefully when cited. Finally, the dating accuracy can be attainable only when the carbon-14 dates are analysed in the light of cultural character.
