摘　　要：介绍清理后的一个地层单位———龙潭组。江苏地层清理项目组以现代地层学理论为指导 ,经 3年多工作 ,搜集了江苏近 10 0年来大量新太古代至第三纪地层资料。以岩石地层为主与生物、年代地层等进行多重划分对比研究 ,从近 3 0 0个地层单位名称中 ,经清理筛选确定采用 10 5个岩石地层单位和 4个非正式岩石地层单位 ,重编了地层表 ,并建立了地层库 ,使江苏地层划分由统一划分发展到多重划分阶段。Longtan Fm, a lithostratigraphic unit after the clearance is introduced. Taking modern stratigraphic theories as guidance, Jiangsu Stratigraphic Clearance Team collected a large amount of stratigraphic information from Archaeozoic Era to Tertiary Period over the last hundred years through the effort of more than three years. The study of stratigraphic division and correlation was conducted to mainly redefine the lithostratigraphy and biostratigraphy and chronostratigraphy. Among nearly 300 stratigraphic units,105 lithostratigraphic units and 4 informal lithostratigraphic units were determined and adopted after clearance. Stratigraphic time table was recompiled and stratigraphic database was set up, developing the stratigraphic classification of a united method into a stage of polyclassification.
