摘要
介绍一种新的元素地球化学分类。根据元素与O^(2-),S^(2-),(S_2)^(2-)的亲合程度或相似程度,可将元素分为呈气元素、类铂元素、喜氧元素、喜硫元素、类铁元素、类氧元素和类硫元素等七大类。该分类的特点是:有利于掌握地壳中元素的主要存在形式、共生组合规律和分布特点,利于正确判断物理化学坏境,深入研究元素的类质同象关系,指导找矿。
A new geochemical classification of elements is introduced. According to to affinity or elements to O^(2-), S^(2-) and (S_2)^(2-), they may be dividedinto seven major types: gaseous, platinum-analogous, oxygen-liking, sul-phur-liking, iron-analogous, oxygen-analogous and sulphur-analogous. Thisclassification is favourable for knowing well the main shape of existence,paragenetic association and distribution characteristics of elements in thecrust, judging correctly the physico-chemical environment, studing thorou-ghly isomorphism and guiding the search for ore deposit.
