摘要
"地质界面"是地壳内各类地质单元的边界,它明确了地质体之间的相互关系,通常也是形成矿床的有利地质空间和载体;"成矿界面"是指地质界面上发生成矿作用的地质记录,记载有成矿作用发生的"地质界面"称它为"成矿界面";讨论"地质界面"上发生成矿作用过程、成矿物质富集条件和矿床形成后保存过程的这一系列完整内容的成矿学理论,称为"界面成矿"理论。在前人研究基础上,匹配相应成矿作用种类,"成矿界面"可以概括分成9个成矿界面组;每类"成矿界面"上发生的成矿作用,都标定了矿床形成的地质位置,均对找矿有指示性意义;界面成矿理论是矿产预测和矿床勘查成矿学的重要依据,是总结成矿规律的基本内容之一,并且可以作为支撑境内外实施科学找矿的有效理论依据。
"Geological interface"is the boundary of various geological units in the earth's crust.It clarifies the contact relationship between geological bodies,and usually also a geological space where the deposit is formed."Metallogenic interface"refers to the place where mineralization occurs and geological interface with the deposit."Marginal metallogenesis"clarifies the occurrence of mineralization at the metallogenic interface and its evolution process,ore-forming material enrichment and post-mineralization preservation process.According to the differences in geological and metallogenic processes,the metallogenic interface can be divided into 9 groups.Metallogenic interfaces are the most easily recognizable and direct indications for prospecting,and constitute one of the theoretical bases of scientific prospecting,and summarize the law of mineralization.
