在复杂的Fe—S矿物系列中,磁黄铁矿是主要的矿物之一。它广泛分布在不同地质作用下形成的硫化物矿床中。本世纪四十年代前后,国外已开始了磁黄铁矿的矿物学研究;六十年代以来,有关资料大增。不少研究者通过对人工合成的磁黄铁矿进行热力学和相平衡的实验研究,获得了磁黄铁矿矿物学、结晶学等方面的丰富资料,指出磁黄铁矿存在着六方相和单斜相两种结构型式,它们之间除具有共同的基本结构型式外,在不同温度条件下,其成分和超结构等又显示出一系列差异。在对比中发现天然产出的磁黄铁矿同样存在这两个相,其成分范围、形成温度及超结构型式与人工合成磁黄铁矿极相近似。磁黄铁 Pyrrhotite is one of the major minerals in the complex Fe-S mineral series. It is widely distributed in different geological formation of sulfide deposits. Around the 1940s of this century, foreign countries started the mineralogy study of pyrrhotite. Since the 1960s, the relevant information has greatly increased. Many researchers through pyrology and phase equilibrium experimental study of synthetic pyrrhotic pyrrhotic obtained pyrrhotite mineralogy, crystallography and other aspects of the rich information that the existence of pyrrhotite hexagonal and single In addition to having a common basic structure between them, under different temperature conditions, the composition and structure of the structure show a series of differences again. In comparison, it is found that natural pyrrhotite also exists in these two phases, and its composition range, formation temperature and super-structure type are very similar to that of synthetic pyrrhotite.
