本文从岩漿分異作用的观点,探討了蒋庙基性侵入岩的形成过程及其有关的岩石学問題:岩体形态和产状,岩漿多中心結晶分異及其分異过程中揮发組份的动态,鲍溫矿物反应系列和磁缺矿的析离成因,磁鉄矿与黑云母、普通角閃石的反应关系和数量消長关系,斜長石双晶特征与其成份的关系,岩石化学成份的对称分異和主要矿物成份的不对称分異,几种岩石变种的形成条件。
In this paper, from the point of view of magma differentiation, the formation process of the Jiangmian-based intrusive rock and its related petrological problems are discussed: the shape and occurrence of the rock mass, the multi-center crystallization of magma and the volatilization in the differentiation process The relationship between the evolution of the Bowen’s mineral reaction series and magnetite ore, the reaction and the relationship between the quantity and the growth of the magnetite, the biotite and the amphibole, the relationship between the characteristics of the plagioclase and its constituents, Symmetric differentiation and asymmetric differentiation of major mineral components, the formation of several rock variants.
