Olympus Mons
Mars
Geographic 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 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
Age
• 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 Cycle
Force
• Both a constructive &
destructive force
• Constructive: creates igneous
extrusive rock (A)
• Destructive: weathering &
erosion of surface over time
(B)
Rock Cycle
• Shield Volcano that creates
igneous extrusive rock (A)
• Weathering & erosion while
volcano is dormant (B)

Formation
Shield Volcano
•
•
•
Shield Volcano with gradual slopes
like the Hawaiian Island volcanoes
Also formed by a hot spot like Hawaii
Gradual
slopes
Large 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
Composition
Rock Type
•
•
•
Made of igneous extrusive rocks
Probably basalt or basaltic andesite
Likely a similar composition to
Hawaiian volcanoes
Scarp 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 Caldera
•
•
•
a composite of up to 7 circular
depressions
40-50 miles across
Created from different volcanic
eruptions
The 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
