本文吸收了一般岩石化学换算法的合理部分,根据稳定矿物组合与化学成分之间的规律性联系,确定了前者的岩石化学特征值.以简单联立方程解出某元素不同矿物中的配比.根据不同岩石化学条件确定成分多变矿物中元素组合和分配方式;并考虑了钾钠长石之间的常见类质同象范围,以确定符合自然实际的矿物组合和含量.计算结果投影于Qu-A-P1三角图,确定矿物成分的岩石命名.本文对各种常见的酸性深成-火山岩都建立了系统的自然矿物换算法和命名系统,其中深成岩系统包括各种含锂的云母类花岗岩、碱性花岗岩、堇青石花岗岩、萤石黑云母花岗岩、榍石角闪石黑云母花岗岩以及黑云母白云母花岗岩等.本换算法改进
In this paper, the reasonable part of general petrochemical conversion method is absorbed, and the petrochemical characteristic value of the former is determined according to the regular relation between stable mineral composition and chemical composition.A simple simultaneous equation is used to solve the ratio of different minerals in a certain element .According to different petrochemical conditions, the composition and distribution of elements in the variable minerals are determined, and the common isomorphic range between potassium and sodium feldspar is taken into account to determine the mineral assemblage and content which accords with the natural reality.The results are projected on Qu-A-P1 triangular map to determine the mineral composition of the rock named.In this paper, a variety of common acidic deep volcanic rocks have established a system of natural mineral conversion algorithm and naming system, including deep diagenetic system, including a variety of lithium-containing mica Granite, alkaline granite, cordierite granite, fluorite biotite granite, hornblende amphibolite granite and biotite mica granite, etc. The conversion method to improve
