| 摘 要： | Underground brine samples were collected along the southern coast of the Laizhou Bay, Shangdong, China in two field investigations in 2003. The brines are confined in the Quaternary sediment and underwent a series of geochemical changes. The redox states of these brines were assessed qualitatively based on the measurements of Eh and redox-sensitive species such as DO, NO NO~, Mn2＋, Fe2＋, SO4^2- in the brines. The redox condition of the underground brine is anoxic, and the redox reactions that controlled the redox potential of brines should be Fe（Ⅲ） reduction and sulfate reduction.

| Abstract: | Underground brine samples were collected along the southern coast of the Laizhou Bay,Shangdong,China in two field investigations in 2003.The brines are confined in the Quaternary sediment and underwent a series of geochemical changes.The redox states of these brines were assessed qualitatively based on the measurements of Eh and redox-sensitive species such as DO,NO NO3,Mn2 ,Fe2 ,SO2-4 in the brines.The redox condition of the underground brine is anoxic,and the redox reactions that controlled the redox potential of brines should be Fe (Ⅲ) reduction and sulfate reduction. |
