Abstract：This work attempts to better understanding the enrichment environment and sources of strontium in groundwater in Xintian county,Hunan Province.Groundwater and rocks on geological profiles were sam-pled and analyzed.The results showed that,(1)Rich-strontium groundwater is present in the strata of D3 s , with contents in order for strata,D3 s >C1 y >D3 x 1 >D2 q ;(2)The average contents of strontium element of springs and shafts are 376.57μg·L-1 and 2,756.87 μg·L-1 ,respectively,1.88 times and 13.78 times the natural mineral water,respectively.Strontium element contents of shafts are much higher than that of de-scending springs,7.32 times the descending spring;(3)The lithology of D3 s is medium-thick or thin layers of light grey marls,intercalated with limestone and shale,in which strontium contents are generally more than 300 mg · kg-1 ,with the highest was 838 mg · kg-1 ,which is the primary source of strontium in groundwater;(4)Many conditions have contributed to the formation of rich strontium in groundwater,such as gentle strata,the low coefficient of precipitation infiltration,planar supplies,and scattered seepage.
