| 中文摘要:文章对第四纪滨海相地下卤水资源的赋存条件、空间分布等卤水地质特征和成矿规律进行了系统的分析和研究。研究表明,浅层地下卤水含水层为1层，赋存在第四系全新统，承压地下卤水含水层为4层，赋存于第四系更新统中；地下卤水来源于海水，系蒸发浓缩成卤，是一种复杂的水盐体系；其中含有Na+、Mg2+、Ca2+、K+、Li+、Rb+、Br-、Cl-、O2-、SO2-4、BO-2、I-等离子，并组合形成多种可溶盐类；主要有益组分为NaCl、Br、MgCl2、MgSO4、CaSO4、KCl、I 、LiCl、Rb2O、B2O3等；达到工业指标的矿种有5种，分别为NaCl、Br、MgCl2、MgSO4、CaSO4；估算的卤水总储量为59.92×10.8 m3。 |

| Abstract:This paper has systematically discussed geological characteristics and ore_forming processes of Quaternary littoral facies underground brine, including its burial conditions and aerial distribution. The results indicate that the water_bearing layer of shadow underground brine is No.1 layer existing in Quaternary Holocene, whereas the water_bearing layers of pressurized underground brine are No.1_4 layers in Quaternary Pleistocene. The underground brine is a complex water-salt system derived from seawater and subjected to intense evaporation and concentration in Quaternary sediments. It is rich in such components as Na+，Mg2+，Ca2+，K+, Li+, Rb+, Br-, Cl-, O2-, SO2-4, BO-2 and I-, forming many kinds of soluble salts. The beneficial components are NaCl, Br, MgCl2, MgSO4, CaSO4, KCl, I, LiCl, Rb2O and B2O3, among which NaCl, Br, MgCl2, MgSO4, CaSO4 have reached their industrial indexes. Total reserves are estimated to be 59.92×10.8 m3. |
