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。
Some fossilized mammalian teeth and antlers collected from various stratigraphical position of primary Sjara-osso-gol sediment are dated by both 230Th and 231Pa 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.
