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

the “research questions”
• What is the origin of Martian volcanoes?
• What are the probable
causes of volcanic activity?
• Could it be an evidence of
some present tectonic activities?

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

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

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.

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

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

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

Where are earth VoLCANoes located?
•Along ocean ridges
•At hot spots
•At subduction zones

Martian VoLCANoes
• Ancient super volcanoes
• More recent activity

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