南京市区的全新世沉积物,发育良好,分布广泛,钻孔众多,录井详细,为开展南京市全新世地层的研究创造了有利条件,但是,由于缺乏系统的孢粉、微古分析和完整的~(14)C测年资料,给全新统的划分和对比也带来了一定的困难。本文试图根据已掌握的现有资料,着重对本区河流冲积相的全新统及其在城市供水和工程建设上的意义,作一初步研究,力求把理论探讨同实际应用结合起来。
The Holocene sediments in the Nanjing urban area are well developed, widely distributed, extensively drilled and well-logging, which has created favorable conditions for the Holocene stratigraphy study in Nanjing. However, owing to the lack of systematic sporopollen analysis and micro-paleoanalysis The complete ~ (14) C dating data have also brought certain difficulties to the division and comparison of the Holocene. This paper attempts to make a preliminary study on the Holocene river alluvial facies and its significance in urban water supply and construction in accordance with the available information available and tries to combine theoretical exploration with practical application.
