中文摘要: 庙后山是位于我国东北的重要中更新世人类遗址。报道该地点出土人类化石的第5、6堆积层次生碳酸盐岩和骨化石样的铀系测年结果。夹生于第6堆积层3个钙板的年龄分别为276、>535、346ka,其下第5层中的钙板为526±31ka,据此第6层顶部应至少为200ka,第5层中部应大于500ka。结果远大于该地点原基于骨化石铀系测年的年代框架,支持中国直立人和早期智人交替比原认为约200ka早得多的观点。
英文摘要: The Miaohoushan site, with the recovery of three hominid fossils, 76 stone artifacts and a faunal assemblage of 72 mammalian species, is known for marking the northernmost human presence in Middle Pleistocene China. This paper presents230Th/ 234U dates on four calcite and two fossil samples from the hominid fossil-bearing 5th and 6th depositional layers of the site. The flowstone intercalated in 5th layer yields an age of 526±30 ka, while three speleothem horizons of the 6th layer give ages of 276, >535 and 346ka respectively. Based on these results we propose that the topmost section of the 6th layer should be no less than 200 ka, and the middle part of the 5th layer older than 500 ka. The results here presented, much older than the previous temporal frame based on the U-series dates on fossil bones, are in support of the proposition for a much earlier Homo erectus-archaic Homo sapiens interface in China.
