南京汤山葫芦洞地质雷达勘探洞穴堆积研究

通过对南京汤山葫芦洞内部东侧地质雷达勘探资料的分析,根据经验值计算,东部洞穴基岩埋深在10m左右,可能为水平状的红色岩系。特殊的地质基础导致葫芦洞成为汤山地区已知规模最大的洞穴。其上的洞穴埋藏堆积可以分为上、中、下三个角砾层,可能反映了该洞穴曾经历过三次较大的崩塌堆积过程。上角砾层可能含有动物化石,是今后古人类考古值得关注的堆积层。

Study on ground penetration radar exploration on sediments in Hulu Cave of Tangshan, Nanjing

Through analyzing the data of Ground Penetration Radar(GPR) exploration in the eastern part of Homo erectus in Tangshan Cave,the authors point out the bedrock of the eastern cave was more than 10 meters thick,probably belonging to flat red rocks.The cave sediments on the bedrock were divided into three breccia layers from the top down,which reflected the cave once underwent a process of serious landslip and deposit for three times.The upper breccia layer is probably rich in animal fossils,which will become the deposit worthy of attention in future archaeology.
