Magnetite: The mineral Magnetite information and pictures

Magnetite is an important ore of iron. Well formed crystals are popular among mineral collectors, and the magnetic Lodestone variety is frequently sold in hobby shops to amateur collectors. Magnetite is also of significant interest to the science community due to its strong magnetic properties.

Magnetite mineral Britannica

Magnetite, also called lodestone, or magnetic iron ore, iron oxide mineral (FeFe 2 O 4, or Fe 3 O 4) that is the chief member of one of the series of the spinel (q.v.) group.Minerals in this series form black to brownish, metallic, moderately hard octahedrons and masses in igneous and metamorphic rocks and in granite pegmatites, stony meteorites, and high-temperature sulfide veins.

Magnetite: Mineral information, data and localities.

Jacobsite-Magnetite Series. Magnesioferrite-Magnetite Series. Magnetite is an important iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007). Extremely thin layers of 200-nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007).

The magnetite at Auen was found in one of these pegmatites in 1996. The actual pegmatite was severly altered, with a clay mineral, albite covered microcline and magnetite as main minerals. Small zircon, molybdenite sheets and a yellow, transparent mineral was present as accessory minerals. Most of the magnetite was partly altered to hematite

Magnetite Wikipedia

Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite

Mineral Gallery The Magnetic Minerals

The Magnetic Minerals are few, but the property is important because of this fact. Once a specimen is established as magnetic, identification becomes a rather routine exercise. The mineral magnetite is named after this characteristic.. Magnetism occurs (most often) when there is an imbalance in the structural arrangement of the iron ions.

Why Is There Magnetite in the Human Brain? RealClearScience

Jun 11, 2019· That iron mineral is magnetite (Fe3O4), and its name is an obvious clue to its most intriguing property: magnetite is the most magnetic of Earth's naturally-occurring minerals. So what is a magnetic mineral doing inside our brains? Caltech geobiologist Joseph Kirschvink thinks he might have the answer: Magnetite allows us to sense Earth's

University of Minnesota’s Mineral Pages: Calcite

Magnetite resembles a number of other metal ores, but it is the only common mineral that exhibits magnetism. So magnetism alone is sufficient to distinguish relatively pure magnetite samples. It is more difficult to distinguish cases where magnetite is mixed with other dark colored minerals, such as hematite and ilmenite.
