Active volcanos


Kos has solfatara fields and hot springs. Most of the rocks are Pleistocene in age. There have not been any eruptions in the last 10,000 years. The solfataras have feeble hydrogen sulfide emanations and thin sulfur deposits.

GYALI (Small island) NISSYROS



Official pages


The island's geological formation, as in most of the Cycladic islands, is composed of sedimentary rocks, formed on the sea bed some ten million years ago. The subsoil consists almost entirely of schists. A small percentage of marble (6 - 7%) can be found mainly on the island's eastern coastline.


  Millions of years ago, Syros, along with all the other islands of this group, formed part of the sea bed. A series of mighty earthquakes lifted the rocks above the sea-level. In the course of countless millenniums, the island progressively took on its actual shape.
  Today, it has a mountainous structure, especially in its northern part (Pano Meria), with Pirgos (442 m) as its highest peak. Here, the hills slope down abruptly, particularly towards the eastern side of the island, where erosion has gouged out medium to large sized holes on the slopes and in the gorges.
  The edge to the right of one of such gorges constitutes a natural border between the northern and southern part of the island, leading down to the bay of Kini and its shallow, sandy beach.
  On the opposite side of Pano Meria, the largest part of northern Syros presents wide and relatively fertile large valleys such as Vari, Possidonia etc.
  The rocky layers that prevail on the island consist of marble and slate, in great diversity. They are the source of important historical information.

  The highest peak of the island is Tsiknias (725 m.). It is situated in the eastern part of Tinos and towers above a channel which bears its name. Here starts the Ikarean Sea. Strong winds often whip through the channel and buffet the mountain. That is why, according to ancient mythology, it was the home of Eol, "the king of winds". The steep and rocky mountain of Xompourgou ( 640 m.) dominates the central part of Tinos.
  The surroundings of the village of Volax are especially beautiful, with round granite rocks cropping out of the infertile soil. Slate prevails on the island, while limestone exists only in the form of marble.
  The island counts several quarries providing an abundance of white and green marble (used in the construction of Buckingham palace and of the Louvre). Minerals are also mined on Tinos, where one finds deposits of chromium, lead, ferrous and manganese minerals, etc.
