2. History
19th century
Mariner 9
Viking
Mars Global Surveyor

3. Location 18.65 °N, 226.2 °W Northwest of Tharsis
23 km tall, km, km
600 km across

5. Timeline
MOC and THEMIS used to find that Noachian period >3.7Ga yielded global volcanism
followed by vent volcanism in Tharsis, Elysium, and Circum-Hellas
later just in Tharsis and Elysium
Activity localized to Tharsis around 1.6Ga
volcanism was active until Ma

6. Effusion
rate of magma supply to Kilauea and Moana Loa averages .01 km3/yr
Volume is estimated to be 2.6*10^6 km^3
Using rate accumulation values given in Hawaii, it would take 130 million years to construct shield volcano

7. Gravity

9. Aureole Deposits Northwest East Flank failure-induced landslides
Ice-Lubricated Gravity Spreading
Glacial Interactions

10. Escarpment 8 km Assymetry Northwest=shallow, southeast=steep Water
Mass movement
Faults

11. Caldera
SiO2 content
Lava fountain  cinders

13. Magma Chamber d<16 km Estimated depth of Martian primary melts

14. Atmospheric Effect Constant column density
~5 decrease in mass from bottom
Low atmospheric density

15. Water
Deep within volcano
Shielded from radiation
East flank- faults

16. Future Landings Difficult to study via rover 8km escarpment Parachute
Dust
