Can Rocks Get Rusty?

What rocks rust?

The red, maroon to deep red ferric oxide (the most powerful pigment of sedimentary rocks) can accumulate locally to form iron ore deposits of commercial importance.

Humid to semihumid climates readily oxidize metallic iron and iron minerals to limonite (ferric hydroxide), common rust..

Why does stone rust?

When iron-containing rocks are near or at the surface, abundant oxygen from the atmosphere or dissolved in water combines with the iron to oxidize it. That process generates “rust” like on those garden tools carelessly left out in the rain.
