A single 40 pound stone was observed to fall near Zagami Rock, Katsina Province, Nigeria on October 3, 1962. A SNC meteorite, Zagami is believed to have originated on the planet Mars and to be a sample of the Martian crust that was in some way ejected from the surface through asteroid impact. Classified as a calcium-rich eucrite achondrite with a young crystallization age relative to other meteorites of 1.3 billion years, Zagami represents an extremely rare class of meteorite.

Zagami is a basalt composed primarily of the pyroxene, augite. The photos show the shiny black fusion crust and granular augite crystals that are the classic hallmarks of this meteorite.
