摘要
元素地球化学场揭示了与门捷列夫周期律相适应的、元素在内生过程中的聚散趋势和空间分布规律。在元素地球化学场展示的 3个不同层次的地球化学断面中 ,花岗岩体断面上成矿元素的析出顺序 ,与元素在周期表中的位置有明确的对应关系。为此 ,从元素自身结构变化的角度 ,探讨这种现象的原因。研究结果表明 ,与花岗岩有关的热液成矿元素的析出顺序和分带规律 ,与元素的离子半径和离子电位密切相关。
The geochemical field of elements (GFE) advanced in the recent years unraveled both the concentration_dispersion trends of elements in endogenic process corresponding to the periodic law, and the spatial distribution patterns of elements in the Earth. Among the patterns, one illustrates the mineral zoning of ore_forming elements on the top and in the roof of a granite body and its relation to the position of the elements in the periodic table. On the basis, this paper tries to search for the reason of this relation. The research result indicates that the mineral zoning mentioned above is closely related to the ionic radius and electric potential of those elements.
