Hydrogeochemical Evolution of Groundwater in Guanzhong Basin
摘要
Abstract
Based on the hydrogeological condit ions ofthe Guangzhong Basin and the hydrochemical characteristics ofgroundw a-ter, the formation mechanism ofunconfined groundw ater was analyzed. The results showed that(1) the types ofgroundw ater chemisty and groundw ater dynamic have horizont alzoning characteristics, and groundwater dynamic field controls the distribu-tion ofgroundw ater chemistry;(2) Cl- concentration and TDS can reflect the intensity ofevaporat ion in the study area;and(3) the ion exchange occurs mainly n groundwater with high salinity in study area. The results ofPHREEQC simulat ion showed that along groundw ater flow direction, the precipitat ion ofcalcite and gypsum and the exchange ofNa+ and Ca2+ occur at paths 1 and 2;w hereas the precipitat ion ofcalcite and dissolution ofgypsum and dolomite, and the exchange ofMg 2+ and Ca2+ in addi-tion to Na+ and Ca2+ occur at path 3.关键词
