Composition:

Name: Zagami - Stone, Achondrite (Martian Basalt)
Location: Katsina Province, Nigeria
Date: 2007
Caption: This meteorite fell in 1962 in Katsina Province, Nigeria. It is believed that it is a fragment of a Martian lava flow. It found its way to Earth when a giant impact on Mars catapulted rock fragments into space. A close look at the black glass veins show they are impact melt that contain Martian gases.

Name: Nakhla - Stone, Achondrite (Martian Calcium-rich Pyroxenite) Meteorite
Location: Alexandria, Egypt
Date: 2007
Caption: This meteorite fell in 1911 in Alexandria, Egypt. It is believed to have formed on Mars based on its dense pyroxene (greenish-gray) and olivine (brown) crystals which are a signature of martian molten rock. It also contains water-bearing minerals.
