The Hydrochemical Characteristics of Underground Brine along the South of Laizhou Bay

Using statistical methods,the hydrochemical characteristics of underground brine was studied in the littoral plain along the south of Laizhou Bay. The results demonstrate that: the main chemistry types of underground brine is Na-Cl and Na-Mg-Cl,and its hydrochemical characteristics consist well with seawater; the coefficients namely rNa/rCl、k/br、rMg/rCa, indicate the underground brines, with greater concentration and weaker metamorphism, originated from seawater.
