一、概述地質学家早已知曉內生金屬矿床与岩漿岩有着空间上和时間上的成因关系,在这些岩漿岩中佔有主要地位的是花崗岩类。换句话说百分之九十以上的花崗岩类与內生金屬矿床有关。摆在地質学家面前的問題是如何理解与內生金屬矿床有关的这种花崗岩类。因为这个问题是有用矿产的新的找矿和勘探标誌。近几十年来岩石学家对这个问题进行了專門性的研究。关于該类岩石成因方面的問题已刊登于“花崗岩問題”的兩卷集中,作者不于重述。这里着重指出的是組成該类岩石矿物相对含量方面的問題。
I. Overview Geologists have long known that there is a spatial and temporal genetic relationship between endogenous metallogenic deposits and magmatic rocks. Granite rocks dominate these magmatic rocks. In other words, more than 90% of the granite and endogenous metal deposits related. The issue before geologists is how to understand this type of granite associated with endogenous metallogenic deposits. Because this issue is a new prospecting and exploration symbol of useful minerals. In recent decades, petrographers have conducted a special study on this issue. Questions about the genesis of this type of rock have been published in the two volumes of Granite Problems, and the author will not repeat them. It is highlighted here that the composition of the relative content of rock minerals in question.
