Biotite Wikipedia

Biotite is a common group of phyllosilicate minerals within the mica group, with the approximate chemical formula K(Mg,Fe) 3AlSi 3O 10(F,OH) 2. It is primarily a solid-solution series between the iron-endmember annite, and the magnesium-endmember phlogopite; more aluminous end-members include siderophyllite and eastonite. Biotite was regarded as a mineral species by the International Mineralogical Associationuntil 1998, when its status was changed to a mineral group. The term biotite is still used to describe un

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).

Magnetite Earth and Environmental Sciences

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. If enough magnetite is present to give the sample a magnetic character

Difference Between Magnetite and Hematite Definition

31/01/2018· Main Difference Magnetite vs Hematite. A mineral deposit is a naturally occurring deposit that is unusually rich with a particular mineral. If a mineral deposit is composed of a metal that can be extracted using existing technological methods, then it is called an ore. Magnetite and hematite are two forms of iron ores from which iron can be extracted. Magnetite contains iron in the form of
