摘要/Abstract

摘要： 南京市东郊汤山镇石灰岩洞穴堆积物中发掘到直立人头骨和大量哺乳动物化石，具有重大科学意义。本文采集该化石层堆积物顶部钙板上连生的石笋，进行铀系测年，给出化石层年龄上限在42＋∞－7万年B.P.，提示该地点年代超出原有估计。从石笋氧同位素的古气候曲线对比，该层似位于第11氧同位素段，大致与北京猿人洞穴堆积的第8－9层相当。

Abstract: Hulu Cave, 16km to the east of the centre of Nanjing ( 32°N, 119°E) , with the discovery of hominid cranium and an abundance of mammal fossils, is considered as one of the mo st important paleoanthropological sites in China. The fossil o f Nanjing Man w ill provide important evidence for human evolution.
A stalagmite developed o n the capping flow-stone layer of the Hulu cave has been dated by U-series method, giving an age rang e of 417_ 207ka. While the age result of its core ( TSX, 417+ ∞- 74 ka) indicates the possibility of a still older age of the site, the study o n the paleoclimatic strategraphy tends to place the travertine layer a tδ18 O Stag e 11. Therefore, the fossil containing layer ca n be roughly correlated with 8th-9th Layer o f Zhoukoudian Palaeoanthropological Cave.
