柳林泉域岩溶水化学演化及地球化学模拟
Hydrochemical evolution and geochemical simulation of karst groundwater in Liulin springs
摘要
Abstract
To reveal the evolution mechanism of groundwater quality in Liulin karst system in northern China,we used the major ions and saturation indices to analyze the hydrochemical characteristics and geochemical processes.Meanwhile,we established a reverse geochemical model to quantitatively simulate the water-rock interactions in karst aquifers.The results showed that the hydrochemical type changed from HCO3-Ca·Mg in the recharge area to HCO3·SO4-Ca·Mg in the runoff area and to HCO3·SO4-Ca·Na in the discharge area.The ge-ochemical processes of hydrochemical evolution in karst water were the dissolution of carbonate minerals and gypsum.Along the flow path, the processes were evolved from the simultaneous dissolution of calcite and dolomite in the recharge area to the dissolution of dolomite and gypsum in the runoff area,and the dissolution of halite was added in the discharge area.Besides,the dedolomitization and cation exchange between Na+and Ca2+in the runoff and discharge areas affected the hydrochemical types of karst groundwater in Liulin.关键词
