(1)研究阐明了贵州热矿水若干组分(特别是氟与钙)的相关特征及其形成机理;并与北方高氟地下水做了比较。进行了自然界可能形成的硫酸水(pH4)和碳酸水(pH4)对碳酸盐岩的溶蚀作用研究。研究表明,硫酸水(pH4)体系对碳酸盐岩的溶蚀能力比碳酸水(pH4)的要弱得多。阐明了强酸(硫酸)和弱酸(碳酸)对碳酸盐岩的不同的作用机理。(2)运用热力学分析的计算的方法,近似地计算了给定条件下,辰砂溶解度达成矿意义的浓度时的Eh下限。
(1) The study clarified the relevant characteristics and formation mechanism of several components of Guizhou thermal mineral water (especially fluorine and calcium); compared with the North China high fluoride groundwater. A study was conducted on the dissolution of carbonate rocks by sulfuric acid (pH 4) and carbonated water (pH 4) that may form in nature. Studies have shown that the sulfuric acid (pH 4) system is much less corrosive to carbonate rocks than carbonated water (pH 4). The different mechanism of action of strong acid (sulfuric acid) and weak acid (carbonic acid) on carbonate rock is elucidated. (2) Using the calculation method of thermodynamic analysis, the lower limit of Eh is obtained when the concentration of cinnabar dissolution reaches the significance of mineralization under a given condition.
