the day we became

Research scientists

...and were asked to provide hints in order to study Martian geology

Class II E SL A.Diaz Caserta(Italy) Mars-rover Stromboli Team

• What are the probable causes of volcanic activity?

• What is the origin of Martian volcanoes?

• What is the origin of Martian volcanoes?

• Could it be an evidence of some present tectonic activities?

evaLuating and interpreting results

All Martian volcanoes are mid–plate locatedSimilar SF similar composition

SF = d/h

what does the volcano shape depend on?

A hotter lava flows more quickly than a colder one

Let us consider a property of a fluid related to its resistence in flowing…

… and depending on fluid chemical composition and

temperature.

ExPERIMENTs: fluids behaviour

The high viscosity of chocolate is a model of a Peléan eruption.

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

Peléan eruption

After the eruption, a “spine” of solidified lava grew and then collapsed.

Peléan eruption is named after

the volcano Mount Pelée …

…that destroyed the whole city of Saint-Pierre, Martinique, on May 8th 1902

Class II E SL A.Diaz Caserta(Italy) Mars-rover Stromboli Team

More researchWe simulated two different eruptions…

…and the presence of crystals in lavas

• effusive (Hawaiian) eruption

• explosive (Peléan) eruption

Class II E SL A.Diaz Caserta(Italy) Mars-rover Stromboli Team

… and we proved that

The shape of each volcano depends on lava viscosity

Where are earth VoLCANoes located?

•At subduction zones• At hot spots• Along ocean ridges

The most famous hot spot on Earth …

What’s up on Mars?

Class II E SL A.Diaz Caserta(Italy) Mars-rover Stromboli Team

Martian VoLCANoes

• Ancient super volcanoes

• More recent activity

conclusions and SUGGEstions

1. Collecting rock samples from the surroundings of various volcanoes

2. Setting up a network of seismographs

• All Martian volcanoes belong to the shield type and are mid-plate located

• There is no more tectonic activity on Mars
