Distribution and type of volcanic vents on Milos. Simplified from Fytikas and others (1986).
Milos is a Pliocene to Holocene stratovolcano with no historic eruptions. Effusive rocks (domes and lava flows) make up most of the island. Solfataras and fumeroles, some with temperatures up to 100 degrees C, are active on the island. There are sulfur mines on the southeast coast.
Chemical composition of rhyolite lava from Milos (from Georgalas, 1962):
SiO2 TiO2 Al2O3 FeO MnO MgO CaO Na2O K2O P2O5
75.6 0.42 12.81 1.78 - 0.12 1.68 3.30 3.32 -
- = not measured.
FeO = FeO total.
Milos has the potential to produce geothermal energy but the residents have voted against development.
