根据涂光炽教授的定义,改造成矿作用系指地层、基底或深部的某些成矿元素在后期地质作用或地壳运动中受到活化迁移,然后在构造软弱部位富集成矿的过程。他把改造与岩浆、沉积、变质四种矿床类型并列作为矿床的分类基础。因此改造作用是一种重要的成矿作用。 改造矿床也是金矿的重要矿床类型,按照成矿物质来源还可进一步将改造型金矿床分为下述亚型:
According to Professor Tu Guangchi, the remolding of mineralization refers to the activation and migration of some metallogenic elements in the strata, basement or deep during the later geology or crustal movement, and then the enrichment of mineralization in the weak parts of the structure. He put the transformation and magmatic, sedimentary, metamorphic deposits of the four types of juxtaposition as the basis for the classification of the deposit. Therefore, the role of transformation is an important mineralization. Mine alteration is also an important gold deposit type, according to the source of ore-forming material can be further transformed gold deposits are divided into the following subtypes:
