摘要
根据16个全新统底部^(14)C样品的年龄测定,证明把全新世底界的年龄定在11000a B.P.前后是合适的,但云南几个样品的年龄数据明显偏老一千多年,这可能与纬度有密切关系,因而中国全新世与晚更新世的年龄有随地区而异的现象。因此,我国全新世底界划分仍需要进一步讨论。
According to the ^(14)C dating on sixteen samples from lowest boundary of Holocene in our laboratory, it is cleared that the age of lowest boundary of Holocene to be determined around 11 000 years should be available. But the radiocarbon dates of some samples from Yunnan Province are evidently older than that. Perhaps, the age of lowest boundary of Holocene in Yunnan may be related to the variation of latitude. So the age of the boundary between Holocene and Pleistocene would be discussed further in China.
