Volcanism on Mars
Videos
Volcanic activity, or volcanism, has played a significant role in the geologic evolution of Mars. Scientists have known since the Mariner 9 mission in 1972 that volcanic features cover large portions

First X-ray diffraction view of Martian soil – CheMin analysis reveals minerals (including feldspar, pyroxenes and olivine) suggestive of "weathered basaltic soils" of volcanoes in Hawaii (Curiosity rover at "Rocknest", 2012). Each ring is a diffraction peak that corresponds to a specific atom-atom distance, which are unique enough to identify minerals. Smaller rings corresponds to larger features and vice versa.

Alba Mons

Alba Mons is a volcano located in the northern Tharsis region of the planet Mars. It is the biggest volcano on Mars in terms of surface area, with volcanic flow fields that extend for at least 1,350 k

Central caldera complex of Alba Mons. The calderas are shallow compared to those on other Tharsis volcanoes. Within the larger caldera is a small shield capped by a concentric circular feature (near center). Image is about 200 km (120 mi) across (THEMIS daytime IR mosaic).
