city. A wide undersea canyon extends to the south of the area where these rivers flow into the Antalya Gulf. Offshore from the Aksu's mouth, there is no canyon; there is instead a shallow marine shelf where the river deposits sediments in a broad area. West of the Aksu basin is a 30x40 km-wide area of tufa and travertine deposits that mark the SW boundary of the basin; the city of Antalya is built on top of this area. These deposits were formed from prehistoric cold springs in the early Pleistocene. They are deepest at the west end, where they are 250 m deep; they get shallower towards the east and are 30 m deep at the easternmost part. A narrow band of limestone deposits stretch from Gebiz in the north to the Küçük Asar Tepe hills in the south. This is known as the Gebiz limestone and was likely deposited from shallow coral reefs on the east side of the Aksu basin. There are abundant gastropod and bivalve fossils in these deposits.
