近几年来,作者比较系统地研究了在5Kbar压力下的霞石(Ne)-六方钾霞石(Ks)-石英(Qz)三元系和霞石-六方钾霞石二元系;在一个大气压和过冷却条件下的透辉石-钙契尔马克分子体系及透辉石-钠长石-钙长石体系,同时根据相图中物相的特征,结合岩浆的形成作用,开展岩石成因的研究,取得了一些进展。 1.实验方法;高压实验在内加热高压釜中进行,高温炉由白金丝或钼丝制成,利用氩气作压力介质,样品座的两端均有热电偶
In recent years, the authors systematically studied the nepheline (Ne) -hexagonal Ks-quartz (Qz) ternary system and the nepheline-hexagonal potash nepheline binary system under the pressure of 5Kbar. In one Diopside-Cazier molecular system and diopside-albite-cadavellite system under atmospheric pressure and overcooling conditions, and according to the characteristics of phase facies and magma formation, rock genesis The research has made some progress. 1. Experimental methods; high-pressure experiments were carried out within a heated autoclave, high-temperature furnace made of platinum wire or molybdenum wire, the use of argon as a pressure medium, the sample holder has a thermocouple
