| Abstract: | During the investigation process of the environmental and geological problems in Caofeidian area,the chemical components and compounding characters of samples in Caofeidian area are used to research the groundwater chemical formatting mechanism combined with the hydrogeology conditions.It is suggested that the dissolution-precipitation process of the halite,carbonate minerals,and silicate mineral in the aquifer is the main effect of the shallow groundwater,while the poor-Magnesium calcite and gypsum have little effect.Meanwhile,the intense evaporation-concentration has important influence on the hydrochemical features of the shallow groundwater.The dissolution-precipitation process of silica-alumina salt,sodic soil and halite effects the deep groundwater heavily.Besides,the mixinng action and the cation exchange happen along the flow path.The evaporation effects the river water besides dissolving the halite,silica-alumina salt and sulfate salt. |
