| Abstract: | The shallow groundwater in Hangzhou area has the characteristics of high mineralization, high salinity and high contents of iron and manganese. Statistical analyses and the experiments of simulation show that the Holocene transgressive strata has a crucial effect on the formation of chemical composition of the shallow groundwater in the plain area of Hanghzhou. The degree of transgression is in consonance with the variation tendency of the thickness of the transgressive strata. The chemical compositions of the subsurface water in the hilly area depend on the lithology of the aquifers. |
