Magnetite
Magnetite is a naturally occurring iron oxide mineral with the chemical formula Fe3O4. It is known for its strong magnetic properties and is one of the primary ores of iron, playing a significant role in both geology and industrial applications. The crystal structure of magnetite is cubic, which contributes to its magnetic characteristics and its presence in various geological environments.
Magnetite: Meanings, Properties, Facts and More
Magnetite Mineral is a group belonging to the spinel group and its chemical formula is Fe3O4. It has an octahedral crystal system with a hardness of 5.5 – 6 on the Mohs scale. The distinct features of magnetite include being black or brownish-black in color, having metallic luster, opaque transparency, and good cleavage along one direction.
Magnetite
Magnetite (empirical formula Fe 3 O 4) is the oldest magnetic mineral known to man. Being the most abundant magnetic mineral in terrestrial rocks of igneous and metamorphic origin, magnetite has helped paleomagnetists to reconstruct the ancient geomagnetic field from rocks, and with it, the past positions of the continents on the globe.
Formation of magnetite-(apatite) systems by crystallizing …
Magnetite-(apatite) ore deposits are interpreted as being formed by the crystallization of iron-rich ultrabasic melts, dominantly generated by the interaction of silicate melts with oxidized P-F-SO4-bearing sedimentary rocks. This hypothesis is supported by geologic evidence, experimental studies, numerical modeling, stable and radiogenic isotope …

Magnetite
Magnetite is found in igneous, metamorphic, and sedimentary rocks. As its name implies, it is magnetic; it and other inherently magnetic iron-containing minerals are described as being ferrimagnetic. Magnetite is in the hexoctahedral crystal class; in the 3-D crystal structure, the purple atoms are iron, and the red atoms are oxygen.
