If subduction carries hydrous minerals deep into Earth’s mantle, they may “rust” the iron outer core, forming vast sinks of oxygen that can later be returned to the atmosphere.
The magnetic and color properties of the mineral hematite give clues to past environmental conditions and is being used for paleoclimatic reconstruction.
A comparative study of urban, semi-urban, and rural sites reveals that the species of atmospheric iron varies depending on location.
New high-pressure experiments on fluid iron suggest thermal convection without compositional buoyancy is sufficient to drive the dynamo generating Earth’s magnetic field.
Water pressure on mid-ocean ridges may affect magma production kilometers beneath the ocean floor.
In a cave accessible only by daredevil divers, extraordinary microbial colonies metabolize nitrogen and iron nutrients and possibly remove pollutants from water.
A new study explores the possibility of cubic iron alloy structure at our planet's core.
Fungi and bacteria deposit metal ions on steel objects left behind by miners. These metals form strange clam-like shells on the steel surfaces.
