regression of the Miocene sea, limestone sediments continued to develop especially around the lakes near pit
areas. Volcanic activities started at the end of Pliocene and continued till the end of Pleistocene. Volcanosedimenter
formations occurred at Erdemli Plain. Terrestrial debris belonging to Pleistocene covered the valley
base of Sorgun Stream and Erdemli Plain by drifting as discordant over the formations belonging to Pliocene. The
travertines evolved in between the coastal plain and plateau area.
