摘　　要：通过对国内许多矿床统计发现,斑岩型矿床、矽卡岩矿床、铜镍硫化物矿床中普遍发育大量的磁黄铁矿,因此许多学者选择以磁黄铁矿为切入口对其矿物学特征展开研究,从而以点带面指示出与矿床学相关地质意义。结果表明,通常采用磁性胶法、电子探针分析法、X射线粉晶衍射法、LA-ICP-MS原位微区分析法和Re-Os同位素年代学分析法等对磁黄铁矿展开研究,从而识别磁黄铁矿及其类型、判别矿床成因及成矿物质来源。According to the statistics of many deposits in China,a large number of pyrrhotite are found in porphyry deposits,skarn deposits,copper-nickel sulfide deposits,and syngenetic sedimentary superimposed modified deposits,.Therefore,many scholars choose pyrrhotite as an entry point to study its mineralogical characteristics,so as to indicate the geological significance related to Mineralogy by point belt surface.The results show that the methods of magnetic colloid,electron probe analysis,X-ray powder diffraction,LA-ICP-MS in situ microanalysis and Re-Os isotopic geochronology analysis are usually used to study pyrrhotite,so as to identify the type of pyrrhotite,the genesis of the deposit and the source of mineralizing materials.
