Greece is a natural geological laboratory, which allows us to understand the current active geodynamic process of the Greek orogenic arc, which includes earthquakes, volcanoes, coastal movements, and other geological processes of uplift and subsidence in various regions, as well as intense erosion, transportation, and deposition of sediments. At the same time, it is a significant geological museum that reveals the complex history of the region during the last 300 million years of our planet's existence. Through the study of Greece's rocks, ancient oceanic basins can be detected, such as in Northern Pindos and Orthry, ancient crystalline rocks of the Paleozoic era, ancient granitic and volcanic rocks, as well as characteristic phases of limestone and other sedimentary rocks, which contain fossils of both coastal neritic phase and pelagic or abyssal phase. The more recent sediments reveal the continuous change of Greece's paleogeography, with areas of lakes, plateaus, bays that transform into new forms of islands, peninsulas, or high mountains, etc. All of the above are included in the book that describes the tectonic structure of the geological layers and other rocks of Greece, as well as the successive stages of paleogeographic and geodynamic evolution in the wider Mediterranean region.
