Thrace Basin Thrace Basin The European side of Turkey is called the Thrace Basin. It is the largest and thickest Cenozoic sedimentary basin in Turkey. The basin is triangular shaped, trends WNW-ESE and was formed by extension in late Middle Eocene to latest Oligocene times. This gas prone basin is located northwest of Istanbul, Turkey. About 9,000 meters of Eocene-Miocene marine clastics and continental sediments were deposited. Several basement faults were reactivated and underwent strike-slip motion in late Miocene times where the famous North Anatolian Fault bounds the southern part of the basin. The Cenozoic sedimentary succession, overlying Paleozoic to Mesozoic metamorphic
East Thrace be Mediterranean in character. It can descend to about 12°C and can rise to about 32°C, similar to Asian Turkey. East Thrace has an area of 23,764 km (3 percent of the country), slightly smaller than Sardinia, and a population of about 11 million people or about 14 percent of the total population (in 2015); the population density is around 430 people/km, compared to about 80 people/km for Asiatic Turkey, which is also called Anatolia or Asia Minor. However, densities are skewed by the metropolis of Istanbul. The two continents are separated by the Dardanelles, the Bosphorus (collectively known as
