Magnetite is found in igneous, metamorphic and sedimentary rocks. It is also the mineral with the highest amount of iron magnetite crystals, which typically occur when the earths magma cools at a slow enough rate for crystals to form and settle outside the magma. Magnetite also occurs in banded iron formations and in lake and marine sediments.

Hematite is one of the most abundant minerals on Earths surface and in the shallow crust. It is an iron oxide with a chemical composition of Fe 2 O 3. It is a common rock-forming mineral found in sedimentary, metamorphic, and igneous rocks at locations throughout the world. Hematite is the most important ore of iron.
magnetite mgntt , lustrous black, magnetic mineral, Fe 3 O 4. It occurs in crystals of the cubic system, in masses, and as a loose sand. It is one of the important ores of iron (magnetic iron ore) and is a common constituent of igneous and metamorphic rocks. It is found in Norway, Sweden, the Urals, and various parts of the United States.
Oct 14, 2020 Magnetite is one of several prominent iron oxide minerals found in Missouri. These minerals are composed of the elements iron and oxygen. Large magnetite deposits in Missouri are found in the southeast part of the state and are related to igneous rocks that are approximately 1.4 billion years old. This magnetite specimen is a rare.
Magnetite has a black or brownish-red color and a black streak. It has a hardness of about 6 on the Mohs hardness scale. It is one of two minerals in the world that is naturally magnetic. Magnetite, also known as lodestone, is found throughout the United States. Magnetite is an important source of iron ore and occurs in many igneous rocks.
You can find them in Norway, Germany and Italy. There are some other places also where you can find magnetite and the places are mostly located in the United States. It can be found it in the states of Oregon, New Jersey, Pennsylvania, North Carolina, Virginia, New Mexico, Utah and Colorado. You can also found the mineral in countries like ...
Jun 21, 2005 Small grains of magnetite occur in almost all igneous rocks and metamorphic rocks as well as many sedimentary rocks. Magnetite is a valuable source of iron ore. It dissolves slowly in hydrochloric acid. Large deposits of magnetite are found in Kiruna, Sweden, and in the Adirondack region of New York in the United States.

Feb 08, 2008 Iron is the most magnetic of the three. The mineral magnetite (Fe3O4) is a naturally occurring metallic mineral that is occasionally found in sufficient quantities to be an ore of iron. The principle ores of iron are Hematite, (70% iron) and Magnetite, (72 % iron). Taconite is a low-grade iron ore, containing up to 30% Magnetite and Hematite.

Sep 27, 2016 Abstract. Biologically formed nanoparticles of the strongly magnetic mineral, magnetite, were first detected in the human brain over 20 y ago Kirschvink JL, Kobayashi-Kirschvink A, Woodford BJ (1992) Proc Natl Acad Sci USA 89(16)76837687. Magnetite can have potentially large impacts on the brain due to its unique combination of redox activity, surface charge, and strongly magnetic behavior.
