The mineralogical form of green rust is a recently discovered fougerite.

Fougèrite is a relatively recently described naturally-occurring green rust mineral.

Particular minerals that can be used include green rust, magnetite, pyrite, and glauconite.

Another, more alert animal had just bolted away, recognizing the green rust bucket that serves as the cow catcher's truck.

It was based on the novel The Green Rust by Edgar Wallace.

All forms of green rust (including fougerite) are more complex and variable than the ideal iron(II) hydroxide compound.

However, a short exposure of green rust to atmospheric oxygen is sufficient to oxidize it back to ferrihydrite, making it a very elusive compound.

The reactive surface of ZVI in alkaline waters is a ferrous coating such as green rust.

The anaerobic corrosion of iron leads first to the formation of ferrous hydroxide (green rust) and can be described by the following reaction:

At low temperature, the anaerobic corrosion of iron can give rise to the formation of "green rust" (fougerite) an unstable layered double hydroxide (LDH).

Scientists have also found that certain iron minerals, like green rust, magnetite, and pyrite, also have reductive capabilities although they contain ferrous iron rather than ZVI.

Green rust is a powerful reducing agent and also a layer double hydroxide (LDH) capable to sorb anions because of the presence of positive electrical charges borne on its surface.

This precipitate is also known as "green rust" in the crystal lattice of which iron(II) ions are easily substituted by iron(III) ions produced by its progressive oxidation.

Other forms of rust exist, like the result of reactions between iron and chloride in an environment deprived of oxygen - rebar used in underwater concrete pillars is an example - which generates green rust.

Under reducing conditions as those found in gley soils, or in deep environments depleted in oxygen, and often with the assistance of microbial activity, ferrihydrite can be transformed in green rust, a layered double hydroxide (LDH), also known as the mineral fougerite.

Indeed, a gas pressure build-up could occur if the rate of hydrogen production by the anaerobic corrosion of carbon-steel and by the subsequent transformation of green rust into magnetite should exceed the rate of diffusion of dissolved H in the pore water of the formation.

Wallace's other science fiction works include The Green Rust, a story of bio-terrorists who threaten to release an agent that will destroy the world's corn crops, 1925, which accurately predicted that a short peace would be followed by a German attack on England, and The Black Grippe, about a disease that renders everyone in the world blind.
