| 摘 要： | 在评述已有经典分类基础上给予了元素地球化学亲合性的明确概念。强调了阳离子与阴离子或与络阴离子(酸根)之间的选择结合的重要地球化学意义,并以其做为元素地球化学分类的依据,提出了分类的新方案。该分类方案将元素划分为:亲石元素、亲氧元素、亲硫元素、阴离子及两性元素和氢及惰性气体元素五个类。阐述了各类元素亲合规律的基本特征和元素亲合性与地质环境的关系。

| Abstract: | On the basis of reviews of classical geochemical classification of elements, the writer presents a clear definition of geochemical affinity of elements.The geochemical significance of the tendency of selective combination between eation and anion or coplex anion (acid radical) is emphasized, and then, according to the tendency of the selective combination among elements and the existing state of elements, the writer classes elements into litho-phile elements, oxgenophile elements sulphophile elements, anions and am-phiprotic elements hydrogen as well as ineet(gas) elements. |
