摘要/Abstract

摘要： 用铀子系法中的~(230)Th增长法测定了河套人与萨拉乌苏文化的年代。并用~(231)Pa增长法对所测年代的可靠性作了检验。根据测得数据,萨拉乌苏组的沉积时代不早于晚更新世中期,其上部不超过三万年,下部为距今3—5万年左右。考虑到人化石及旧石器的出土层位,河套人与萨拉乌苏文化的年代应为距今3.7—5万年左右。

Abstract: Some fossilized mammalian teeth and antlers collected from various stratigraphical position of primary Sjara-osso-gol sediment are dated by both 230Th and 231 Pa methods.
The results are:
1) The lower Sjara-osso-gol formation (lacustrine deposition) was accumulated between 30—50 thousand years B.P. The "Ordos man'' and "Sjara-osso-gol Culture,, are located in this formation.
2) The upper Sjara-osso-gol formation (alluvial deposition) is dated no more than 30 thousand years B.P.

Key words: Uranium series dating; Ordos man; Sjara-osso-gol Culture
