| 摘 要： | 上海地区第四纪以来沉积的松散沉积物，地层和沉积环境具有显著的空间差异。本文利用松江地区第四纪钻孔的测年、有孔虫、孢粉等测试资料，研究阐述了过渡沉积区地层发育和沉积环境特征，为地层厘定及全面认识上海地区第四纪地质演化规律提供依据，并为地层的区域对比研究提供参考。

| Abstract: | The Quaternary sediments are about 200~400m thick in Shanghai area, with remarked temporal and spatial variations in strata and corresponding depositional environments. A Quaternary borehole （SG11 core） was drilled in Songjiang area of Shanghai, where the thickness of sediments is about 200m, belong to transitional depositional area. The study of SG11 core includes lithology, grain size of sediments, foraminifera and pollen. Based on these analyses, this paper reconstructs the strata framework and sedimentary environments in the transitional depositional area, to discuss the Quaternary geological evolution of Shanghai area on the basis of previous studies, and further provide theoretical basis for the study of regional hydrogeology and engineering geology in this area. |
