Weathered meteorites. ~95% of meteorites contain between ~10 and ~20% metallic iron when they fall. This iron begins to rust after landing on Earth: a freshly fallen meteorite won’t be rusty, but ~95% of meteorites will begin to show at least minor oxidation within weeks to months. After a few decades, they’ll be ~thoroughly rusty.

Cassidyite (Ca 2 Ni[PO 4] 2 × 2H 2 O) is a rare mineral from Wolf Creek Crater (found in cracks and cavities in weathered meteorites).
