What rocks contain magnetite?
Magnetite is found in igneous, metamorphic and sedimentary rocks.
Where is magnetite most commonly found?
Distribution of deposits Magnetite is sometimes found in large quantities in beach sand. Such black sands (mineral sands or iron sands) are found in various places, such as Lung Kwu Tan of Hong Kong; California, United States; and the west coast of the North Island of New Zealand.
How is magnetite formed?
Magnetite is formed by the reaction between ferric iron mats and Fe(II) anaerobically. Magnetite could precipitate directly in the Archean ocean. The high temperature and high Fe(II) seafloor vents fluids favors magnetite deposition.
What is the mineral group of magnetite?
magnetite, also called lodestone, or magnetic iron ore, iron oxide mineral (FeFe2O4, or Fe3O4) that is the chief member of one of the series of the spinel (q.v.) group.
What environment does magnetite form in?
Magnetite is a common natural phase, occurring in various geological environments, ranging from igneous (e.g., layered ultrabasic rocks, basalts) to sedimentary (e.g., banded iron formations, beach sands) rocks, and to high-grade metamorphic rocks (e.g., schists, skarns), where it can be produced through a multitude of …
Where does magnetite in sand come from?
As it turns out, the sand is largely composed of an iron ore called magnetite, which, as its name suggests, is highly magnetic. It’s derived from the erosion of igneous rocks in the Sierra Nevadas.

Is magnetite a magnet?
Magnetite is a mineral whose primary component is an iron oxide that contains equal amounts of iron(II) and iron(III). As its name implies, it is magnetic; it and other inherently magnetic iron-containing minerals are described as being ferrimagnetic.
How do you get magnetite?
Magnetite is a raw material found abundantly in the Mountains and Mountains Caves, as well as within the Jellyshroom Cave and Lost River. Magnetite can be found as a large resource deposit.
Does magnetite contain nickel?
Both magnetite and meteorites have high levels of iron, which is one reason they are easily mistaken for each other. Most meteorites contain an iron and nickel alloy, while terrestrial rocks like magnetite most often do not contain nickel.
Is magnetite in a rock?
Magnetite is a very common iron oxide (Fe3O4) mineral that is found in igneous, metamorphic, and sedimentary rocks. It is the most commonly mined ore of iron. It is also the mineral with the highest iron content (72.4%).
