The Volcanic History

The Basal Volcanic Complex (ca. 160,000 to 100,000 years)
The Early Caldera Stratovolcano (ca. 100,000 to 30,000 years)
Lakki Pyroclastics and Avlaki Complex
Lacustrine and Pyroclastic Formations
The Melisseri - Evangelistra - Afionas Complex
The Emborios Complex
The Ellinika - Kyra - Lies Pyroclastic Complex
The Argos - Stavros Complex
The Main Caldera Formation (30,000 to 15,000 years ?)
The First Caldera Phase (?30,000 to 20,000 years ?)
The Second Caldera Phase (20,000 to <15,000 years ?)

Lacustrine and Pyroclastic Formations

In the northeastern part of the internal caldera, two volcaniclastic sediments crop out on cliffs, divided by a few meters of basaltic-andesite lava, indicating the presence of an earlier caldera prior to the main caldera formation.

In addition, similar tuffitic sediments also appear in the northwestern part of the island, here interbedded with beach conglomerates. These lacustrine beds represent sedimentation of dominantly volcanic input within an aqueous system (Volentik et al. 2002).

 

 


Methodologies     

Several methodologies are applied in a completely new way to achieve the necessary results.
