Magnetite and hematite are common minerals in a range of mineral deposit types. These minerals form partial to complete solid solutions with magnetite, chromite, and spinel series, and ulvospinel as a result of divalent, trivalent, and tetravalent cation substitutions.

Hematite: The mineral hematite information and pictures

Hematite is one of the most common minerals. The color of most red and brown rock, such as sandstone, is caused by small amounts of Hematite. It is also be responsible for the red color of many minerals. Non-crystalline forms of Hematite may be transformations of the mineral Limonite that lost water, possibly due to heat.

Magnetite in the human body: Biogenic vs. anthropogenic | PNAS

Oct 25, 2016 · Magnetite is an iron-oxide mineral that occurs naturally on Earth. Because it is also an important component of many anthropogenic materials (e.g., coal fly ash) and synthetic products (e.g., black toner powders), magnetite can be released to the environment through human activities (1). In PNAS, Maher et al. (2) describe the abundant presence in the human brain of magnetite .

MAGNETITE (Iron Oxide) - Amethyst Galleries Mineral Gallery

Magnetite is an oxide of iron (as is hematite).It is not a component of ordinary rust, although it can form as iron oxidizes in a dry environment. When you see sparks from welding operations or from iron striking a hard surface (as when it is held against a spinning grinder), the sparks are due to the rapid (and exothermic) oxidation of tiny particles of iron into magnetite.

Magnetite - an overview | ScienceDirect Topics

Magnetite is widely distributed usually with octahedral, or spherical, morphology, in igneous and metamorphic rocks. Magnetite is also found in limestones, in fumerolic deposits, and in living forms. For the latter the mineral plays some very important role, which we highlight in Section 8.04.3.3.2.

Serpentinite - Metamorphic Rocks

Serpentinites form as a result of serpentinization.

Different types of this mineral are mined from the iron mines in various parts of the world. Naturally occurring hematite is found in different colors including black, brown, metallic gray, and red. A common characteristic of all these types is the presence of a rust red streak in them. The name 'hematite' in Greek means blood.

Identifying Minerals | Geology

Many minerals in an introductory geology lab do not exhibit their crystal form. If a mineral has space while it grows, it may form natural crystals, with a crystal shape reflecting the geometry of the mineral's internal crystal lattice. The shape of a crystal follows the symmetry of its crystal lattice.
