摘　　要：通过偏光显微镜、电子探针、面扫描等方法手段,对磁铁矿的地球化学特征进行了系统研究,以期对成因研究有所裨益。研究发现,马坑铁矿的4种类型磁铁矿并不是同一种成因类型,也不是简单一次形成的,而是不同地质成矿作用共同作用的产物,综合认为马坑铁矿属海相火山热液沉积—热液叠加改造的变质型铁矿床。By means of polarizing microscope,electronic probe and surface scanning,systematic study on geochemical characteristics of magnetite is carried out in the hope of benefiting genesis study.The study shows that four types of magnetite in Makeng iron ore mine don＇t belong to the same genesis type and they aren＇t simply formed at a time.They are the products of combined actions of different geological mineralization.It＇s concluded from above that Makeng iron ore belongs to marine volcanic hydrothermal sediment-hydrothermal superimposed and transformed metamorphic iron ore deposit.
