Magnetite is often not very abundant, but it can be found in many different types of igneous, metamorphic, and sedimentary rocks. It can even be found in some meteorites. Most igneous rocks that form deep underground contain a small amount of magnetite crystals. Magnetite can also be found in metamorphic rocks that formed from iron-rich .

Regional metamorphism is metamorphism that occurs over broad areas of the crust. Most regionally metamorphosed rocks occur in areas that have undergone deformation during an orogenic event resulting in mountain belts that have since been eroded to expose the metamorphic rocks.

They are often seen in igneous and metamorphic rocks and sometimes seen in sediments near the magnetite source area. The magnetite crystals in this photo are about eight to twelve millimeters in maximum dimension. Magnetite as "Lodestone" Normal magnetite is attracted to a magnet, but some specimens are automagnetized and have the ability to .

. Magnetite is a highly magnetic iron oxide mineral that usually forms octahedral or modified dodecahedron crystals. Magentite is found in high temperature igneous and metamorphic rocks and in sulfide veins. Magnetite has also occurred within pieces of meteorite. Black to Brownish colored Magnetite is similar in appearance to Hematite with a .
Magnetite ore often occurs in metamorphic rocks, which formed from ferruginous sediments in both regional and contact metamorphic settings. It is commonly formed by the reduction of hematite and ferric hydroxide minerals in these rocks. Banded Precambrian iron formations commonly contain magnetite ore. Magnetite is characteristically recognised .
Metamorphic rock - Major features: The most obvious features of metamorphic rocks are certain planar features that are often termed s-surfaces. The simplest planar features may be primary bedding (akin to the layering in sedimentary rocks). As the rock crystallizes or recrystallizes under directed pressure, new crystals may grow in some .
