英文摘要	The Ordos Cretaceous Groundwater Basin,located in an arid-semiarid area in northwestern China,is a large-style groundwater basin.SO~(2-)_4 is one of the major harmful components ingroundwater.Dissolved SO~(2-)_4 concentrations,and delta~(34)S-SO~(2-)_4 and delta~(18)SO-SO~(2-)_4 in groundwater from 14 boreholes and in gypsum from aquifer were analyzed.Results show that SO~(2-)_4 in shallow groundwaters originates from precipitation,sulfide oxidation,and dissolution of stratum sulphate,with a big range of delta~(34)S values,from-10.7 to 9.2,and addition of SO~(2-)_4 in deep groundwater results from dissolution of stratum sulphate,with bigger delta~(34)S values,from 7.8 to 18.5,compared with those in shallow groundwater.This research also indicates that three types of sulphate are present in the strata,and characterized by high delta~(34)S values and high delta~(18)SO values-style,high delta~(34)S values and middle delta~(18)O values-style,middle delta~(34)S values and low delta~(18)O values-style,respectively.The delta~(34)S-SO~(2-)_4 and delta~(18)O-SO~(2-)_4 in groundwater have a good perspective for application in distinguishing different groundwater systems and determining groundwater circulation and evolution in this area.
