| 摘 要： | 较系统地研究了苏州市铁表至其下３０ｍ的浅层第四系的岩性、岩相、物质成分、古生物类型等特征，将该区浅层第四系划分为８层，除楔层为人工填土外，其余７层自上至下依次对应于湖沼相、河流泛滥沉积、强潮河口堆积、潮汐沉积、滨海浅滩相、浅海相、陆相冲积沉积等积成因类型。

| Abstract: | The shallow Quaternary system in Suzhou urban district above the depth of 300m can be divided into seven beds descendingly including artificial filling earth, limnetic faces, overflow sediments or rivers,macrotidal accumulation of river mouth,tidal sediment,littoral shoal facies,shallow-sea fades and continental alluvial sediments. The origin of shallow Quaternary system are determined as interval oj B. p 300033000a above respectively,according to the data of 14C dating micropaleotology,fossils and stratigraphic correlation. The research result is of great significance for the study of palaeogeographic environmental changes,city planning and engineering design in Suzhou city. |
