Ümitli Yaylasý’nýn (Gündoðmuþ, Antalya) jeolojik ve jeomorfolojik özellikleri

Çözünme yoluyla oluþan maðaralar yerbilimcilere arazide karþýlaþtýklarý problemlerin çözümünde önemli katkýlar saðlar. Manaloðlu ve Karaçal Daðlarý arasýnda kalan Ümitli Yaylasý’nda yüzey ve yeraltý karst süreçleri yoðun olarak gözlenmektedir. Orta Toroslarda yer alan Ümitli Yaylasý, Antalya ilinin Gündoðmuþ ilçesine baðlýdýr. Yaylada, 2011 yýlýnda yapýlan araþtýrmalar sonucunda yaklaþýk 2 km2’lik alan içerisinde 18 adet yeni maðara keþfedilmiþtir. Bu çalýþmada inceleme alanýnýn sayýsal yükseklik modeli oluþturularak, maðaralarýn konumlarý bu haritaya iþlenmiþtir. Havza kenarlarýndaki faylara paralel olarak geliþen çalýþma alanýndaki maðaralarýn oluþum ve geliþim süreçlerinde çatlak ve kýrýk sistemlerinin etkili olduðu gözlenmiþtir. Ayrýca, profilleri çýkarýlan maðaralar oluþum modellerine göre incelenerek, Ümitli Yaylasý’nýn karst taban seviye deðiþimleri ve çalýþma alanýnýn lito-stratigrafik özellikleri hakkýnda bilgiler edinilmeye çalýþýlmýþtýr.

Geological and geomorphological characteristics of the Ümitli Plateau (Gündoðmuþ, Antalya)

Solution caves provide important contributions to geologists in solving the problem in the field. In the Umitli Plateau, between Manaloglu and Karaçal Mountains, intensive terrain and underground karst processes are observed. The Ümitli Plateau is situated in the Central Taurus which is located at the Gündoðmuþ district, province of Antalya. 18 caves were discovered in a 2 km2 area with the research performed in 2011. In this study, digital elevation model of the study area was plotted and the locations of the caves were processed in the digital elevation model. It has been observed that cracks and fractures are effective in the formation and development of caves that are parallel to the faults on the side of the basin. In addition to that, the profiles of the caves has been plotted and they were examined according to the cave formation models to obtain information about the karst base level changes of the Ümitli Plateau and the litho-stratigraphic characteristics of the study area.
