类质同象普遍存在于矿物中，将发生类质同象置换的元素列于元素周期表中，就是作者所编制的元素的类质同象置换简表，表中同时列出了主要载体矿物及参考工业指标。利用该表可以很快地查到可能替代主元素的其他元素，有助于研究矿物中可能富集的元素及矿床、岩石的元素组合，指导矿产综合评价 Homomorphisms are commonly found in minerals, and elements that undergo homoplasmic homomorphism are listed in the Periodic Table of the Elements, which are the isomorphic substitutions of the elements of the author’s formula. The table also lists the major carrier minerals And reference to industrial indicators. The table can quickly find other elements that may replace the main element, which can help to study the elements that may be enriched in minerals and the elemental assemblage of ore deposits and rocks, and guide the comprehensive evaluation of mineral resources
