Summary:
This paper presents general data and characteristics that
govern hydrothermal systems and in particular the characteristics that
present the hydrothermal system of Thermopylae. Hydrothermal systems
of Thermopylae and the wider area, are the surface event
of the active hydrothermal field that formed around the volcanic
center of Lichades. The volcanic islands of Lichades are located in the main
part of the Northern Gulf of Evia and consist of trachyandesitic lavas
aged 0.5 Ma. The intense tectonism and fault systems of the area
have contributed significantly to the circulation of hydrothermal fluids. The
Thermopylae hot springs are powered by a deeper motherboard
hydrothermal fluid in which groundwater has been mixed. The deepest
hydrothermal fluid is a mixture of local groundwater (⁓26.3%), marine water (⁓56%) and magmatic water (⁓17.7%). The magmatic contribution is between 1.5% and 3.8%.
