Environmental Implications of Hydro-chemical Characteristics of Gypsum Holes in Salt-gypsum Bed
The typical meaning drip,pool water,atmospheric precipitation and soil water of the gypsum geode under gypsolyte as a research background were choosed.Analysis the hydrochemical feature and forming process of the gypsolyte and draw a conclusion: The content of the main hydrochemical parameter of the gypsolyte within this range,K+ between 0.45~7.22 mg/L,Na+ between 0.4~3.92 mg/L,Mg2+ between 20.27~310.45 mg/L,Ca2+ between 70~338 mg/L,Cl-between 0.38~3.37 mg/L,SO2-4 between 81.31~958.12 mg/L,HCO-3 between 73.2~207.4 mg/L,TDS between 562~1 780 mg/L.The average ion mass concentration shoes that the concentration of the SO2-4、TDS is high and the concentration of the K+、Na+、Cl-is low.On the time series,the hydrochemical type of the researchful area is divided into five categories: heavy calcium carbonate~water,calcium sulfate~water,magnesium sulfate~calcium type water,heavy calcium carbonate~magnesium type water and heavy magnesium carbonate calcium sulfate~water.Among these,the calcium sulfate~water as main type for researching.Meanwhile with the total hardness,TDS,water temperature and pH can be draw a conclusion that the chemical property of the water is weakly alkaline low salinity (micro) hard water.The water's chemical property from rainfall to cave water is heavy calcium carbonate-water to magnesium sulfate-calcium type water.
