Magnetite, ideal formula Fe 3 O 4, is an intriguing mineral not only because it is formula could be written as Fe 2 + Fe 3 + 2 O 4, which more precisely designates one of its contains both ferrous (Fe 2 +) and ferric (Fe 3 +) ions, implying synthesis, growth, and stability within an environment where oxidized and reduced states of iron are present and maintained.

· We identify the abundant presence in the human brain of magnetite nanoparticles that match precisely the hightemperature magnetite nanospheres, formed by combustion and/or frictionderived heating, which are prolific in urban, airborne particulate matter (PM). Because many of the airborne magnetite pollution particles are <200 nm in diameter, they can enter the brain directly .

Magnetite is an iron oxide mineral component of primitive Earth. It is naturally synthesized in different ways, such as magma cooling as well as olivine decomposition under hydrothermal conditions. It is probable magnetite played a significant role in biogenesis. The seawater used in the current work contained high Mg2+, Ca2+ and SO42minus; concentrations, unlike the seawater of today that ...

· The first mineral on our tour was quartz. Most weeks, we''ll only cover one mineral, but there was a very strong push to include magnetite hematite when I polled the blogosphere, so I chose to add both. Both magnetite (Fe3O4) hematite (Fe2O3) are iron oxides. However, the oxidation state of iron.
