Minerals, Rocks Rock Forming Processes

Minerals in the Earth's Crust. There are more than 3000 known minerals (the number is still growing), but of these only about 20 are very common, and only 9 of these constitute 95% of the crust.These 9 minerals are all silicates, and are also called the rock forming minerals.They can be subdivided into two groups, the mafic and felsic minerals according to the principal rocks types they mainly

Magnetite (Fe3O4) Fe3O4 PubChem

A compound can have many different names. For example, acetone (CH3C(=O)CH3) is also known as propanone, propan-2-one, or dimethyl ketone. The brand name of a product is commonly used to indicate the primary chemical ingredient(s) in the product (e.g., Tylenol, a common pain killer, is often used for acetaminophen, its active ingredient).

Resolution of a Big Argument About Tiny Magnetic Minerals

Tiny grains of magnetite, an iron oxide mineral, from a Martian meteorite are markedly similar in size, shape, and composition to the little oxide magnets used by bacteria on Earth and different from other naturally formed magnetites.Is this good evidence for life on Mars? Or did the Martian magnetite grains form by another process? Our studies reveal that the planes of atoms in the Martian

Because magnetite is the only known biogenic mineral in higher organisms which is ferromagnetic at room temperature [Lowenstam, 1981 ; Lowenstam and Kirschvink, 1985), it is important to review briefly the history of its discovery in animals and what is known of its phyletic distribution and biological function.

Magnetite in the human body Biogenic vs. anthropogenic PNAS

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 nanoparticles
