В.И.斯米尔诺夫在最近发表的文章(见苏刊《金属矿床地质》1975年第4期)中,把内生金属的矿质来源划分为三大类:1)与玄武岩岩浆有关的地壳下初生型;2)与花岗岩类岩浆有关的地壳中同化型;3)非岩浆淋滤型.在地壳演化过程中,各种矿质来源所占的比重有明显的变异.太古代以二、三类占绝对主导地位;元古代起主导作用的是同化
In a recent article by Smirnov (see SOL Journal, Geological Geology of Minerals, No. 4, 1975), the mineral origin of endogenous metals is divided into three categories: 1) basaltic magma Crustal primary anomaly; 2) crustal assimilation associated with granitic magmatism; 3) non-magmatic leaching type.During the evolution of the crust, the proportions of various mineral sources have obvious variations, Three types accounted for the absolute dominance; Proterozoic played a leading role in assimilation
