Gulf of Corinth basin : ウィキペディア英語版 | Gulf of Corinth basin
The Gulf of Corinth is an active extensional marine sedimentary basin thought to have started deforming during the late Miocene - Pleistocene epoch. The dimensions of the Gulf of Corinth are approximately 105 km long and 30 km wide with a basement depth of 3 km at its center. This half graben basin is formed by a N100°E-oriented rift which separates the Peloponnese peninsula from the continental mainland of Greece.〔 Currently the Gulf's rift is opening at rate of 10–15 mm/yr, with respect to the Eurasia Plate.〔〔〔 The basin is bounded by the Peloponnese highlands to the south and the westward-moving Anatolian Fault to the north. Major and minor fault planes make up the north and south margins, and its north-south extension is due to activity along a E-W to NW-SE oriented coastal southern margin. The basin's active and inactive faults create associated syn-rift sediment fill. These aspects provide a unique opportunity for scientists to study the tectonic and stratigraphic development of a rift, while further understanding how a basin is actually made. It is postulated that crustal extension is related to a combination of factors: westward movement of the North Anatolian Fault, gravitational collapse of the thickened Hellenide orogenic crust, subduction, and slab roll back of the African Plate at the Hellinic trench.〔〔 As Africa subducts beneath the Aegean Sea Plate the slab essentially pulls the over-riding plate with it, inducing extension. Rifting occurs as the plate stretches weakening the thickened crust causing its collapse upon itself, creating the basin. ==Fault Activity==
