摘　　要：在矿物中普遍存在着标型特征,金属矿物中也不例外,本文以磁黄铁矿为例分析下其矿物标型的意义。磁黄铁矿存在于自然界的主要为单斜磁黄铁矿和六方磁黄铁矿,通过对其成分、结构和共生矿物的标型特征的分析,来了解矿物的生成地质环境,并可以根据相图分析以及公式磁黄铁矿形成的温度、逸度等参物理化学数。There are standard characteristics in minerals,and metal minerals are no exception.This paper takes pyrrhotite as an example to analyze the significance of mineral standard.Pyrrhotite exists in nature mainly in monoclinic pyrrhotite and sixparty pyrrhotite,and the characteristics of its composition and structure syngenetic minerals are analyzed,it understand the geological environment of mineral formationThe physical and chemical parameters such as temperature and fugacity of the formation of pyrrhotite can be analyzedaccording to the phase diagram and the formula.

关 键 词：磁黄铁矿 成分标型 结构标型 共生矿物
