为配合南京直立人生存时代和环境的研究，我们对南京汤山葫芦洞洞穴次生碳酸盐沉积物开展了年代学，同位素地球化学和显微岩相学等分析．６支石笋和５层钙板的ＴＩＭＳ铀系年龄测定结果表明，本区洞穴碳酸盐的发育时段几乎覆盖了０．５ＭａＢ．Ｐ．以来的地质时期。近３０...
In line with the research of Nanjing Homo erectus’s survival time and environment, we carried out chronology, isotope geochemistry and microlithography analysis of the secondary carbonate sediments of the Gushu Cave in Nanjing. The TIMS uranium ages of six stalagmites and five calcium plates show that the developmental period of cavernous carbonate in this area almost covers 0.5MaB. P. Since the geological period. Nearly 30 ...
