摘要: 在进行南京市城市立体地质填图试点工作中，经钻探于仙林大学城发现一套新近系含膏砂泥地层，可与六合灵岩山雨花台组沉积地层对比。该地层的发现对于重新认识南京地区某些相类似断陷盆地基岩面之上的松散覆盖层的结构很有意义，对其在环境地质和工程地质中的影响进行了评述。同时，对地下水参与成矿作用进行了初步论述。

Abstract: A sequence of Neocene gypsum-beating sandy and muddy strata has been recently found in the Xianlin University City, Nanjing, by drilling during urban stereo geological mapping in key areas of Nanjing. This sequence of strata may be correlated with sedimentary strata of the Yuhuatai Formation in Lingyan Mountain, Liuhe district, Nanjing. This discovery is of great significance in reunderstanding the structure of the loose cover above the bedrock surface of some similar downfaulted basins in the Nanjing area. In addition, the influence of its discovery on the environmental and engineering geology of the area is evaluation and the participation of groundwater in mineralization is also discussed.
