From the exhibit

Nakhla is 1.3 billion years old, but a meteoroid impact blasted it from the surface of Mars only about 10 million years ago.

From the exhibit

Nakhla formed on Mars when dense pyroxene (greenish gray) and olivine (brown) crystals settled out of molten rock. It contains water bearing minerals, supporting the idea that the Martian valleys shown here once carried water.
