南京喀斯特溶洞碎屑充填物的沉积特征和气候地层学研究

Sedimentologies and Climatic Stratigraphy Study on Clastic Sediment of Karst Cave in Nanjing

对南京汤山地区的雷公洞炼灰厂剖面进行了沉积学、气候地层学分析．研究结果表明，洞内碎屑充填物记录了２个冷暖、干湿变化旋回，可对应于深海氧同位素曲线的１２～１５段，由此推测南京猿人生存时代大致在４５万年前左右．

This paper addresses on the characteristics of sedimentologies and climatic property stratigraphy of the Lianhui Chang profile in Leigong Cave in Tangshan,Nanjing.The results shows that the clastic sediment recorded 2 cold warm,dry wet cycles corresponding to Stage 12～15 of deep sea Oxygen isotope,from which the deposite layer containing huminid cranium could be deduced to be 450 Ka.B.P.
