Olympus MonsOlympus Mons
Geographic LocationGeographic Location:• Located in the northern part of planet Mars
• Part of the Tharsis Region on Mars
• Which contains several other huge volcanoes
• Olympus Mons is the largest volcano in the solar system
• At 27 km high and 600 km across
Tectonic LocationTectonic Location:• Mars has no tectonic plates that move
horizontally
• There is a possibility of vertical crust movement
• Hot lava would push upward through the crust
AgeAge• Extinct Volcano
• Age determination of some of its lava flows show it is older than 200 million years
• Crater counts show that some regions of he volcano are only 2 million years old.
Force & Rock CycleForce & Rock CycleForceForce• Both a constructive &
destructive force• Constructive: creates igneous
extrusive rock (A)• Destructive: weathering &
erosion of surface over time (B)
Rock CycleRock Cycle• Shield Volcano that creates
igneous extrusive rock (A)• Weathering & erosion while
volcano is dormant (B)

FormationFormationShield VolcanoShield Volcano• Shield Volcano with gradual slopes• like the Hawaiian Island volcanoes• Also formed by a hot spot like Hawaii
Large sizeLarge size• 3 times the size of Mt Everest• due to no tectonic plates on Mars• The hot spot keeps feeding the same
volcano• Mars’ gravity is 1/3 our gravity• Its crust is also thicker and stronger• Therefore the mass of the volcano
doesn’t cause it to sink into the crust
Comparison of Olympus Mons to Mt. Everest
Gradual slopes
CompositionCompositionRock TypeRock Type• Made of igneous extrusive rocks• Probably basalt or basaltic andesite• Likely a similar composition to
Hawaiian volcanoes
Scarp FeatureScarp Feature• Scarp or steep slope surrounds the
edge of the volcano• Scarp is up to 4 miles high. • Lava flows drape over the scarp in
places
Summit CalderaSummit Caldera• a composite of up to 7 circular
depressions• 40-50 miles across• Created from different volcanic
eruptions
The FutureThe Future• Olympus Mons is considered to be extinct
• However, eruptions have occurred as recently as 2 million years
• It is possible that Olympus Mons could erupt in the future
• Weathering & erosion will continue to affect Olympus Mons
• If Olympus Mons became active again over a period of time:– enough gases could be released to warm the atmosphere – This could produce water again on the surface of Mars
