摘要
离子电位是影响溶液中元素存在形式和迁移能力的重要控制因素,大多数元素的富集成矿都会经过流体介质的搬运迁移过程,在此过程中,元素大多是以离子或络离子形式存在;而离子电位影响着金属阳离子的活动性和络合物形式,同时制约离子或络离子的性质和迁移能力。作者通过分析离子电位与元素丰度、巨型矿床数目和离子绝对硬度以及离子绝对电负性之间的关系,探讨了离子电位对金属元素成矿的作用和影响。
Ionic potential is an important factor controlling occurrence and migration of elements in the solution. The ore-formings of most elements in strata are controlled by migration processes of fluids. In this process, elements present themselves as ions or complex ions, and ionic potential impacts the activities and the complexation forms of metal ions, and such determines the properties and migration ability of ion or complex ion. In this article, the au- thor discussed the role of ionic potential in the mineralization of metal elements by elucidating the interrelations a- mong ionic potential, elemental abundances, the number of giant deposits, ion absolute hardness, and ion absolute electronegativity
