摘要
本文用氨基酸外消旋测年法,对“元谋人”所在地层中伴生的动物化石进行了测定工作。试图以此探讨“元谋人”的年代。本文以钱方(1985)由古地磁方法推定的与元谋人化石邻近层位的猪牙化石年龄是距今167万年为依据,采用“校正法”求出k_t值。所测结果为距今154万年。
The age of Yuanmou Man has been dated at 1.7 + 0.1 Ma.Bp. by palaeomagnetic method.
This paper is the first study of the age of Yuanmou Man by the method of amino acid. The samples were the fossil teeth-Sus sp. and Cervus sp. analysed by gas chromatographic method. They contain Ala. Val. Gly. D-allo-leu.L-iso-leu. Leu. Ser. Pro. Asp. Met. Phe. GJu. D-β-phe. Tyr. Lys. Arg. His. Try. They are dated at 1.54 Ma.BP. .
