1974年以来,实验硫化物矿物学在多元体系、硫盐体系的研究方面,尤其是对它们在低温时的状态研究方面,又取得了许多引人注目的成就。本文从以下三个方面介绍近几年所取得的新进展。 1.Fe-S体系及磁黄铁矿实验研究的新结果:Fe-S体系高于300℃时的相关系,在60年代业已详细研究。它仅包含黄铁矿(FeS_2)和磁黄铁矿(Fe_(1-x)S)两个相。但随着温度下降,这个体系就变得相当复杂,它至少包含18个矿物相和合成相。其中最有意义的、也是最
Since 1974, experimental sulphide mineralogy has made many remarkable achievements in the study of multivariate systems and sulfur salt systems, especially in the study of their state at low temperatures. This article introduces the new progress made in recent years from the following three aspects. 1. New Results of Fe-S System and Pyrrhotic Experimental Study: The correlation of the Fe-S system above 300 ° C has been studied in detail in the 1960s. It contains only two phases, pyrite (FeS 2) and pyrrhotite (Fe 1-x S). But as the temperature drops, the system becomes quite complex, containing at least 18 mineral and synthetic phases. One of the most significant, but also the most
