钒钛磁铁矿石检测分析

Detection and Analysis of Vanadium Titanium Magnetite Ore

钒钛磁铁矿因为氧化、偏析或蚀变等作用,所产生的次生矿物与微组织很小(小于1μm),若以光学显微镜与扫瞄式电子显微镜的分辨率无法确定钒钛磁铁矿的超威组织时,则进一步利用穿透式电子显微镜来观察其超威组织。并可利用择区电子绕射和EDS分析来获得极微小矿物的结构和成份数据。因此利用SEM可进一步确认矿物相的结构、化学成分与共生关系。文章研究的目的是要了解岩石中的钒钛磁铁矿是如何演变、磁性矿物的特征与成因,希望能进一步了解磁化的过程。

The secondary minerals and microstructures of vanadium-titanium magnetite are very small(less than1μm)due to oxidation,segregation(exsolution)or alteration.If the resolution of optical microscope and scanning electron microscope is not used to determine vanadium When the ultra-wei structure of titanomagnetite,the transmission electron microscope is further used to observe the ultrawei structure,and the selected area electron diffraction and EDS analysis can be used to obtain the structure and composition data of the extremely small minerals,so the SEM is used The structure,chemical composition and symbiotic relationship of the mineral phase can be further conf irmed.The purpose of this research is to understand how the vanadium-titanium magnetite in the rock evolves,the characteristics and genesis of magnetic minerals,and hope to further understand the process of magnetization.
