Aegean Arc
Magmatism in the Aegean Arc is caused by the northward subduction of the African plate underneath the Aegean microplate. This has caused volcanism, which started more than 4 Ma ago. Only the islands of Santorini and Nisyros can be considered to be active nowadays.

Even though many studies have been devoted to magmatism in the Aegean arc, most of the work has been focused on the island of Santorini, and comparatively little on the other, now volcanically inactive, islands. We would like to find out whether there are along-arc differences in the magmatic products, that can be related to geodynamic parameters, such as crustal thickness.

Map of the islands in the Aegean volcanic arc that will be compared to each other: Aegina-Methana-Poros, Santorini and Nisyros.

to the volcano

At least it isn't hard to find out where to find the volcano on the island of Methana.
 
Poros

But it's a lot harder to find anything volcanic on the mini-island of Poros

Aegina Enclave
Both on Methana, and here on Aegina, mafic enclaves are plentiful, indicating the importance of magma mixing in the petrogenetic history of the volcanic deposits

Cape Balos
One of the lesser-known volcanic deposits on Santorini: the basalts at Cape Balos, Akrotori peninsula.
 

REE Santorini

Rare earth element patterns of different deposits on Santorini. The one aberrant pattern (SE234a) is from the oldest deposits on Akrotiri peninsula, which contain hornblende.
