| 摘 要： | 南京地区新近纪地层发育较齐全,生物化石丰富,根据哺乳动物化石最新研究成果,并通过地层对比,将其厘定为中新世早—中期洞玄观组(N1-21d)、中新世晚期的六合组(N31l)和黄岗组(N31h)以及上新统的尖山玄武岩组(N2j)。长江坳陷中砾石层相当发育,如南京附近的雨花台砾石层,安徽境内的安庆砾石层,主要由三套岩性组成,之间均呈假整合接触。第一套归属于六合组(N31l),第二套沿用雨花台组(N2y),第三套为更新统。

| Abstract: | The Neogene strata of the Nanjing Area are relatively continuous and contain abundant fossils. The latest research of mammal fossils and stratigraphic correlation indicates that the Neogene succession in the Nanjing area consists of the Dongxuanguan Formation of the early-middle Miocene, Luhe and Huanggang formations of the late Miocene, and Jianshan Basalt Formation of the Pliocene. Neogene pebbles are common in the Yangtze Syncline, including the Yuhuatai pebbles in the Nanjing Area and the Anqing pebbles in Anhui Province. These pebbles occur in three lithostratigraphic units that are separated by unconformities. These three units are the Luhe Formation, Yuhuatai Formation, and Pleistocene. |
