Geochemical evolution of deep saline and brackish waters in coastal zone of the Primorye region (Far East Russia)

摘要：

The deep saline and brackish waters in coastal zone of the Primorye region have been studied in this investigation. Two types of groundwater are disclosed in wells of studied area: saline water with mineralization (TDS)-4.5-13.7 g/l and brackish water with TDS-2.5-6.0 g/l. Based on δ18O and δ2H isotopic ratios, Na/Cl,Cl/Br ratios, origin and evolution saline and brackish waters have been recognized. Received data indicate that saline waters are result of mixing of ancient seawater with infiltrate waters and brackish water has a meteoric origin and mineralization is forming as a result of water-rock interaction. Mass balance calculation proves that the albite dissolution, with or without deep-seated mantle origin of CO2, is a dominant factor controlling the chemical composition of groundwater.
