Magnetite is a relatively abundant mineral, for it is a minor constituent of many different types of rocks. Where it is sparser disseminated as large grains in some rocks, the characteristic octahedral crystal form of magnetite is often identifiable. However, the grains are most commonly irregular in shape. Being an oxide, magnetite is highly ...
The textural relationships of minerals and the new data set of mineral compositions enable us to examine the occurrence of magnetite and the variation of mineral compositions along a stratigraphic column and to discuss the fractionation processes of magmas and the origin of magnetite in different occurrences. 2. Geological background
Magnetite is very easy to identify. It is one of just a few minerals that are attracted to a common magnet. It is a black, opaque, submetallic to metallic mineral with a Mohs hardness between 5 and 6.5. It is often found in the form of isometric crystals. It is the most strongly magnetic mineral ...
Magnetite is a common mineral with thousands of localities worldwide. It is "a common accessory mineral in igneous and metamorphic rocks in which magmatic segregations or contact metamorphism may produce economically viable deposits [as well as] in sedimentary banded iron formations, [as] a biogenic product, [and in] important detrital ...

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 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, called lodestone, will attract small pieces of ...
Jacobsite-Magnetite Series. Magnesioferrite-Magnetite 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 200-nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007).
