摘要: 本文报道了贵州盘县大洞16个新生碳酸岩样的铀系年代。洞厅前区偏北侧的表层钙板在距今~13万年前形成,该地段因此不存在晚于中更新世的文化堆积。发掘区堆积之上的第二钙板层的生成年代为距今~20万年。若以此速率类推,形成厚~20米的大洞堆积所经历的时间跨度可能较大。有2棵小石笋顶端的年代为~33万年,可代表其延伸钙板下伏堆积所含石制品的最小年龄。上述年代界线表明,大洞是迄今已知贵州最古老、居住时间最长的人类遗址。基于本文数据,年代工作者对初分的大洞地层提出异议,与发掘者经反复勘核后重分地层的设想吻合,这一事实支持具明确层位意义、相对纯净致密的新生碳酸岩样铀系年代的可信度。大洞堆积巨厚,今后的发掘将逐步探明其复杂的地层结构,并可能发现新的适于测年的样品,以进一步确立这一重要遗址的年代位置。

Abstract: Dadong cave, situa ted in Panxian District in Guizhou Province, south-western China, is a recently discovered paleolithic site. This karstic cavern boasts its unusually massive fossil and artifact bearing deposits, being of an area of 9900 m2 and of a thickness of~ 19. 5m. Its 250 meters long main hall is roughly divided into entrance platform, front, middle and rear sections. The first three seasons of excavation, organized in 1992, 1993 and 1996 and concentrated at the centre of the front section, led to the discovery of 2 human teeth, about 2 000 stone artifacts and a rich collection of fossils representing more than 40 mammalian species.
