Hématite — Wikipédia

Hématite sur Mars. On a trouvé, sur la planète Mars, en 2004, des sphères qui pourraient être intégralement ou en partie composées d'hématite. L'hématite se forme habituellement par l'action érosive de l'eau, ce qui suppose la présence, à une époque, d'eau sur Mars.

EtymologyCharacteristicsChemistryPropertiesDistributionSignificanceResourcesSourcesMagnetite is an iron oxide with the chemical formula Fe3O4. Actually, it is a mixture of two iron oxides, FeO and Fe2O3. Therefore, we can show it as FeOFe2O3. According to the IUPAC nomenclature, its name is iron (II, III) oxide. But, commonly we name this as ferrous-ferric oxide. Magnetite got its name because it is a magnet.
