Jan 28, 2012· Magnetite is an iron oxide with the chemical formula Fe3O4. Actually, it is a mixture of two iron oxides, FeO and Fe2O3. Therefore, this can be also shown as FeO·Fe2O3. According to the IUPAC nomenclature, it is named as iron (II, III) oxide. But, commonly we name this as ferrous-ferric oxide.Trace Element Geochemistry of Magnetite from the Fe(‐Cu ...The subtle variations of trace element concentrations within a magnetite grain and between the magnetite grains in the same sample probably indicate local inhomogeneity of ore–forming fluids. The variations of Co in magnetite between samples are probably due to the mineral proportion of magnetite .CARBONATITE DEPOSITS (MODEL 10; Singer, 1986a)Survey, 1991; Haxel, in press).
