  1. MARS-rover

  2. February 11th 2014 the day we became Research scientists ...and were asked to provide hints in order to study Martian geology

  3. the “research questions” • What are the probable causes of volcanic activity? • Whatis the originofMartianvolcanoes? • Could it be an evidence of some present tectonic activities?

  4. analysing sources interpreting data Communicating results

  5. Shield type Cone type VoLCANo CLASSIFICAtION

  6. VoLCANo CLASSIFICAtION shield v. basalt Mauna Loa, Hawaii andesite rhyolite cone v. Stromboli, Italy

  7. evaLuating and interpreting results All Martian volcanoes are mid–plate located Similar SF similar composition SF = d/h

  8. Let us consider a property of a fluid related to its resistence in flowing… what does the volcano shape depend on? A hotter lava flows more quickly than a colder one … and depending on fluid chemical composition and temperature.

  9. v(t)=v0+gt VISCOSITy v(t)=vf(1-e-tβ/m)

  10. ExPERIMENTs: fluids behaviour In our group we tested chocolate cream… … but it was almost still, so we warmed it up. • As a class we tested the effects of • Nature • Temperature • The slanted board angle The high viscosity of chocolate is a model of a Peléan eruption.

  11. Peléan eruption Peléan eruption is named after the volcano Mount Pelée… …that destroyed the whole city of Saint-Pierre, Martinique, on May 8th 1902 After the eruption, a “spine” of solidified lava grew and then collapsed.

  12. More research We simulated two different eruptions… …and the presence of crystals in lavas • effusive (Hawaiian) eruption • explosive (Peléan) eruption

  13. … and we proved that The shape of each volcano depends on lava viscosity

  14. Where are earth VoLCANoes located? At subduction zones • Along oceanridges • At hot spots

  15. The most famous hot spot on Earth …

  16. What’s up on Mars?

  17. Martian VoLCANoes • Ancient super volcanoes • More recent activity

  18. MARs-ology

  19. conclusions and SUGGEstions • All Martian volcanoes belong to the shield type and are mid-plate located • Collecting rock samples from the surroundings of various volcanoes • There is no more tectonic activity on Mars 2. Setting up a network of seismographs

  20. CUrIOsity inquiry discovery Fun! A team effort

  21. Chain Reaction International Express Yourself Conference Sheffield, May 13th 2014 thanks to…
