| Abstract: | Hydrochemistry of underground brines along south coast of Laizhou Bay, Shandong, China has been analyzed. Brine samples were collected from 43 wells in this area. It was considered that the brines were originated from seawater. However, whether they were formed by seawater evaporation or seawater freezing was not fully sure. We created a simple method by plotting Na/Cl vs. seawater concen-tration factor (SCF) and Ca/Mg vs. SCF to determine the brine formation geochemically. Comparison of our results to previous seawater freezing and evaporation experiments indicated that the brines were formed by seawater evaporation. The ratios of HCO3/Cl of some low salinity brines in the study area were relatively higher, indicating that the brines may have mixed with other waters after the generation. The Br/Cl ratios of the brines decreased annually in the past 20 to 30 years of exploitation, indicating down-ward permeation of the brine from which bromine was extracted. |
