  1. Planetary Geology 102 Planetary Volcanism

  2. Planetary Geology 102 • The Moon • plains volcanism, broad shield volcanoes • Mars • large shield volcanoes, smaller cones, plains volcanism • Venus • large shields, coronae, arachnids(?) • Mercury • pits, intercrater plains, smooth plains • Io • low shields, extensive lava flows, paterae, visible eruptions

  3. The Moon • Extensive lunar “maria” (31% of nearside) • Also evidence of discrete sites of volcanism • Many enigmatic sinuous rilles

  4. The Moon

  5. Mars • Long history of volcanic activity • Three primary sites (provinces) of volcanism • Plains volcanism also appears common

  6. Elysium province Tharsis province Circum-Hellas volcanic province Mars

  13. Venus • 80% of the surface is volcanic plains • Shield volcanoes + pancake domes + “ticks” • Crater counts indicate periodic resurfacing

  14. Venus

  15. Mercury • Extensive plains units, possibly volcanic • Spectroscopic evidence for volcanism • Potential intrusive activity

  16. Mercury • Extensive plains units, possibly volcanic • Spectroscopic evidence for volcanism • Potential intrusive activity

  17. Mercury

  18. Io • Most volcanically active in the Solar System • Heat source from tidal flexing • Shields, pits, lava flows, paterae

  19. Io

  20. What aboutnon-silicate magmatism?

  21. Cryovolcanism

  22. Titan • 50% larger than Earth’s Moon • Active methanological cycle • Putative evidence for cyrovolcanism

  23. Titan
