Karpuz Çay Deltasının (Antalya Doğusu) Paleojeomorfolojisi

Abstract

The costal plain formed by Karpuz Çay and Acısu at the east of Antalya Bay is surrounded by low hilly area. This costal plain, which approximately started to form 4000 years ago, is one of the young plains of Mediterranean coasts. In the area under investigation, the geomorphologic units developed on Miocene aged Karpuz Çay and Early-Late Pliocene aged Yenimahalle. Since the drop of sea level occured in Late Pliocene, the oldest morphologic unit in the area is Early Pleistocene aged denudation surfaces. To determine the paleogeographic evolution of the area, the samples taken from boreholes were analyzed. From the results of laboratory analysis and C14 tests, six different period has been identified. To determine the environmental conditions, the morphologic features of the area and the macro fossils are used. From the analysis of samples containing macro fossils, the Cardium edule from Bivalvia family, Cerithidea insulaemaris, Tegula pulliga, Gyraulus intermixtus and Turritella terebra from Gastropoda family were identified. As the ecologic conditions were considered, it was determined that the area is under the influence of sea, and time to time the area was developed fresh water and salt- water features
