Curiosity finds Earth-like rock on Mars

Curiosity Finds First Evidence For Possible ‘Continental Crust’ on Mars.

Most of Mars’ rocks have been produced through volcanism, so the discovery is a surprising and exciting one, and suggests that Mars’ early history was more similar to Earth’s than previously thought. These granite-like rocks are similar to ones in Earth’s ancient continental crust, quite different from the basalt which composes the seafloor. As also noted by the researchers, the rocks “challenge the simple idea of continuous cooling of the Martian mantle over geologic time, pointing to more complex global or local variation in mantle temperature.”
