1. Fusion crust Meteorites that have fallen recently have a black, glassy or ashy crust on their surface.

It is often black and looks like an eggshell coating the rock.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.
