1 PSRDPSRD Spirit PanCam, NASA/JPL/Cornell http://www.psrd.hawaii.edu/May09/Mars.Basaltic.Crust.html presents Mars Crust: Made of Basalt Compositions from Mars meteorites, rovers, and orbiters reveal that Mars is dominated by basaltic rock TES data indicate that most of the surface has been weathered

2 PSRDPSRD Spirit PanCam, NASA/JPL/Cornell http://www.psrd.hawaii.edu/May09/Mars.Basaltic.Crust.html presents Mars Crust: Made of Basalt Compositional variations are more like those of terrestrial tholeiites than calc- alkaline rocks (which form by partial melting of hydrous mantle) Mars basalts might resemble this typical terrestrial tholeiite from Hawaii

3 PSRDPSRD Spirit PanCam, NASA/JPL/Cornell http://www.psrd.hawaii.edu/May09/Mars.Basaltic.Crust.html presents Mars Crust: Made of Basalt Martian meteorites plot along a separate trend than do basalts on Earth This was taken as a distinctive feature of Martian basalts But complete data indicate that most of the Martian surface is more like the Earth on this diagram
