Magnetite Mineral In Different Forms
Magnetite
Magnetite is one of the end members of the ulvospinelmagnetite solid solution series (Fig. ) and is the most common magnetic mineral on is a cubic mineral with inverse spinel structure. The disordering (Curie) temperature varies more or less linearly with Ti content from 150°C for ulvospinel to 580°C for magnetite (Fig. a).
Magnetite: Mineral information, data and localities.
JacobsiteMagnetite Series. MagnesioferriteMagnetite Series. Magnetite is an important, strongly magnetic iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007). Extremely thin layers of 200nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007).

Magnetite ~ Hudson Valley Geologist
· What makes magnetite different from hematite, and strongly magnetic like regular iron, is that it has a different crystalline structure. The ferric iron domains cancel each other out but the ferrous iron domains can be lined up with a magnet making the mineral magnetic (I'm pretty sure that's correct, but don't cite me in a paper if you're a student!).
Magnetite: The mineral Magnetite information and pictures
The mineral Hematite is known to form pseudomorphs over Magnetite. Such pseudomorphs are commonly known as Martite, and their appearance may be very similar to regular Magnetite. However, they differ from Magnetite in that they are only weakly attracted to magnetic fields, and have a reddishbrown streak.
How Magnetite Might Get Into the Brain
· In the early 1990s, biomedical researchers began to notice traces of magnetite — a naturally occurring ferromagnetic mineral and oxide of iron — inside people's brains. That might sound strange, but there has long been evidence that some amount of magnetite might form .
Brain Magnetite
Magnetite is a black mineral form of iron oxide that crystallizes in the cubic or isometric system, namely all crystals which have their crystallographic axes of equal length at 90 degrees to each other. It is a mixed Iron (II) Iron (III) oxide, Fe3O4, and is one of the major ores of iron that is strongly magnetic.

Magnetite
Magnetite is a ferrimagnetic mineral with chemical formula Fe 3 O 4, one of several iron oxides and a member of the spinel group. The chemical IUPAC name is iron(II,III) oxide and the common chemical name ferrousferric formula for magnetite may also be written as 2 O 3, which is one part wüstite (FeO) and one part hematite (Fe 2 O 3).This refers to the different oxidation ...

Magnetite
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
