Neogene sediment deposited after the Alpine cycle outcrops widely. Red line shows the contact between the two plates in the area. Unlike other countries, most of the active faults in Greece are quite visible. Then follows a description of the major sites with archaeological and geological interest. Santorini geology: The present-day crescent shape of the island is a consequence of the activity of the volcano in prehistoric times. Faults are commonly considered to be active if there has been movement observed or evidence of seismic activity during the last 10,000 years. @article{osti_5149399, title = {Geology and geothermics of the Island of Milos (Greece)}, author = {Fytikas, M and Marinelli, G}, abstractNote = {Geothermal research which has been conducted on the island of Milos is reviewed and the island's geology is discussed in terms of the geodynamics of the eastern Mediterranean. Other formations, quite rare, are Asterousia formations and ophiolites (volcanic rocks). Some of the oldest rocks in Greece are from the Paleozoic and are usually metamorphosed with no fossils. Internal and External Zones. Near Corinth, brackish Black Sea water invaded during the Middle Pleistocene, although for the most part, the islands and water area of the Aegean did not change the during the ice ages. Oceanic crust is the part of Earth’s lithosphere that surfaces in the ocean basins, most of the times at depths of thousand meters. Travertine springs often preserve more recent fossil assemblages. Additionally, the Olonos-Pindus Zone extends from Montenegro to Rhodes and is a deep allochthon trough, with clastic Triassic sandstone and the Drymos Limestone. The first writers who have contributed something of geological significance were the ancient Greek philosophers (Adams 1954), such as Thales of Miletus (c.636-546 BC), Anaximander of Miletus (615-547 BC), Pythagoras of Samos (540-510 BC), Xenophanes of Colophon (540-510 BC), Herodotus of Halicarnassu… Feel free to send anything via mail! Peninsular Greece offers stunning scenery and extraordinary sights, including the temple at ancient Delphi, where geology helped produce the oracles' "visions"; Meteora's famed monastaries, perched atop pillars of conglomerate; and the precipitous heights of Mount Olympus. The Prinos Anticline offshore was found to contain oil under Miocene rocks. The Department of Geology offers teaching in many aspects of the broad field of earth sciences. To build the monasteries, the monks had to hoist stone and other materials to the top of these rocks… Mountains in Greece don't soar to the heights of other mountain ranges such as the Andes, Rockies, Alps or Himalayas-but they are extensive. Inland basins preserved numerous mammal fossils such as the Pikermi site north of Athens in continental clay. It consists principally of a number of interconnected plains, floored by alluvium and Pleistocene sediments, and cut off to the north-west by the great mass of Mt Parnes (figure 3.1; Plate 3A). Lavrio, the Secret of Ancient Athens. Geology and Economic Geology of Greece. These areas include Loutra – Samothrakis, Lesvos, Chios, Alexandroupolis, Serres, Thermopyles, Chalkidiki, and many others. The aim of this work is to review all available information on the geology, mineralogy, geochemistry, and fluid characteristics involved in the formation of various gemstones in Greece. The real reason behind the great ancient Greek civilization is the mines of silver, gold, iron and other natural ores. New oceanic crust is forming now in the Atlantic Ocean’s mid-ocean ridge. We now have a Public mailbox! E. Louvari: The Cephalonia Transform Fault and its extension to western Lefkada Island (Greece). In particular the Lavrio silver mine was closely related with the rise and fall of the Athenian Empire (5th – 4th BC). https://en.wikipedia.org/w/index.php?title=Geology_of_Greece&oldid=973619328, Creative Commons Attribution-ShareAlike License, This page was last edited on 18 August 2020, at 07:21. Geology of Greece. The Ionian Zone is thrust westward over the Preapulian Zone and overlain by molasse facies. [4], Herodotus recognized a bitumen well at Limin Keri on the southern end of Zakynthos Island. Greece lies in a geographic position that is favorable to geothermal resources, both high temperature and low temperature. Bauxites indicate a dry time in the Eocene and Oligocene flysch unconformably overlies older carbonates. It includes country boundaries, major cities, major mountains in shaded relief, ocean depth in blue color gradient, along with many other features. A mid-ocean ridge is a general term for an underwater mountain system that consists of various mountain ranges (chains), typically having a valley known as a rift running along its spine, formed by plate tectonics. Geologists subdivide it into the calc-schists, granite, diabase, chert and ophiolite of the Paeonias subzone and the acidic volcanic rocks and limestone of the Triassic-Jurassic Paikon subzone (an old island arc). Greece is a part of the Eurasian plate and in the south the African plate slips under Europe. The Ionian Zone spans much of western Greece with Triassic evaporites overlain by Jurassic neritic limestones. Chapters 3 to 16 are devoted to the geology of different regions of Greece and the Aegean coast of Turkey. Normal faults with four kilometers of displacement are not uncommon although folding is limited—tectonic activity picked up in the Oligocene. Relief and geology provide the basis for describing the Greek landscape in terms of six major regions: central, northeastern, eastern, southern, and western mainland Greece, along with the islands. Greece is one of the few places in Europe you can actually experience the power of earth. The silicified ophiolites of the Almopias subzone, bordering the Pelagonian zone to the northeast represents an old ocean trench. A must see!!! So, after visiting the Acropolis, the Museum and the Ancient Market, you must visit the Lavrio mine and the Temple of Poseidon in Sounio. The central mountain range, the Píndos (ancient Greek: Pindus) Mountains, forms the core of mainland Greece. The Department of Geology, one of the three geology Departments in Greece, was founded in 1977 at the University of Patras, School of Natural Sciences, replancing the pre-existing Chair of Geology. Institute of Geology and Mineral Exploration of Greece (G-IGME) is in fact the Geological Survey of Greece.It was established in 1952 and it operates as a public research institute under the supervision of the Ministry of Environment, Energy and Climate Change. The real reason behind the great ancient Greek civilization is the mines of silver, gold, iron and other natural ores. Geology of Greece. In particular the Lavrio silver mine was closely related with the rise and fall of the Athenian Empire (5. Lavrio mine and the Temple of Poseidon in Sounio. Evolution of the Tethys Alpine System. Greece is one of the few places in Europe you can actually experience the power of earth. High temperature springs, suitable for power generation coupled with heating and cooling, are found at depths of 1-2 kilometers on the Aegean islands of Milos, Santorini, and Nisyros. Quaternary faults are those active faults that have been recognized at the surface and which have evidence of movement in the past 1.6 million years. Beautiful active faults, forming the land, making gorges, valleys, lakes, mountains. Other locations that are promising at depths of 2-3 kilometers are on the islands of Lesvos, Chios, and Samothraki as well as the basins of Central-Eastern Macedonia and Thrace. A hot spring is a spring that is produced by the emergence of geothermally heated groundwater from the Earth’s crust. So, after visiting the Acropolis, the Museum and the Ancient Market, you must visit the Lavrio mine and the Temple of Poseidon in Sounio. Greece mythology and geology. TOURS. Internal zones span between the Serbo-Macedonian Massif and external zones: The Axios Zone, also known as the Vardar Zone, represents the closing of the Axios Ocean and separates the Pelagonian zone from the Serbo-Macedonian Massif. Cave of Pan: next to the ca ve of Zeus . The Geotectonic Zones of Greece. between Eurasia and Africa, opening out to the east. Files are available under licenses specified on their description page. Active faulting is considered to be a geologic hazard and related to earthquakes as a cause. [1]. When you visit Greece, you have a great opportunity to experience some unique geological features: The real reason behind the great ancient Greek civilization is the mines of silver, gold, iron and other natural ores.
