摘要： 金牛山Ａ点剖面分为８层，曾发现有大量化石．１９８４年在Ⅶ层底部见到人骨化石，定名为“金牛山人’．热释光测年结果表明，Ⅵ层下部为１８．８４±１．５１万年；Ⅶ层上部为１９．７０±０．７０万年；Ⅶ层下部为１９．４６±０．３４万年；Ⅷ层上部为３８．８７±５．０７万年．地层年代数据与剖面层序一致，与同层中更新世晚期动物化石时代吻合．可以认为，Ⅵ至Ⅶ层堆积连续而迅速，Ⅶ至Ⅷ层堆积有明显间断．２０万年前，该处曾是一个长时间稳定的洞穴环境．这与“金牛山人”活动所需要的时间与空间相符．

Abstract: Section A at Jinniushan Archaeological Site was divided into eight layers. In i984, some fossil human bones were found at bottom of Layer VII .According to TL dating, the lower part of Layer YI is 188.4±15.1 ka, the upper part of Layer VII( is 197.0±7.0 ka, the lower part of Layer VII is 194.6±3.4 ka and the upper part of Layer VIII is 388.7±50.7 ka. The order of these figures is identical with the stratigraphic sequence. TL ages of the strata are concordant with mammalian fossils found in corresponding layers. It showed that accumulation was quickly and continually from Layer VI to Layer VII. However, between Layer VII and Layer VIII, there was a clear gap in accumulation. About 200 ka ago, the cave might be stable when Jinniushan Man lived.

Key words: TL dating; Archaeology; Jinniushan Man
