中国晚期旧石器的碳-14断代和问题

根据已公布的47个碳-14数据,进而分析10处中国晚期遗址的年代和问题,并提出不同的看法。文中强调:露天遗址中碳-14数据的异常现象,往往与各种原因形成的再次堆积有关。因此必须注意样品的采集和避免引用孤零的碳-14数据,同时还要结合地层和文化性质的分析,才可能保证断代的准确性。

CARBON-14 DATING AND ITS PROBLEMS OF THE LATE PALEOLITHIC IN CHINA

Based on the carbon-14 dates, this article illustrates the dates of ten late paleolithic sites 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.
