摘要/Abstract

摘要： 利用化石中氨基酸的外消旋程度随化石年龄增加而增大的原理,本文分别用“校正法”和“高温法”测定了广西柳州早更新世巨猿洞、中更新世笔架山洞、晚更新世—全新世白莲洞、大龙潭及桂林甑皮岩的一些第四纪洞穴堆积物中牙化石、骨化石或贝壳化石的氨基酸年龄,测年结果与其它地质证据或~(14)C年龄基本一致。

关键词: 氨基酸地质年龄;第四纪化石;广西

Abstract: Based on the principle of racemization degree of amino acids in fossil increasing with its age, this paper has estimated the ages of fossil bones, teeth and shells fron some Quaternary cave deposits in Juyuandong cave (early pleistocene), Bijiashan cave (middle pleistocene), Bailiangdong cave, Dalongtan rockshelter (late Pleistocene to Holocene) in Liuzhou, Zengpiyan rockshelter (holocene) in Guilin, Guangxi. The results are basically consistent with 14C ages or have been supported by other geological evidences.

Key words: Amino acid geologic age; Quaternary fossil; Guangxi
