Abstract

The Bor Plain, which is located in the Middle Kızılırmak subregion of the Central Anatolia Region, extends 14 km toward the west of Niğde. The fan delta deposition system in the southwest of the Bor Plain was formed on the fault-controlled foothills of Mt. Keçiboyduran. The fandelta sequence shows that a paleolake formed during a phase because of the mineralogical content and frequently changing facies. Additionally, clay minerals and herbaceous plants reflecting humid and arid climatic conditions illustrate the lake-level changes. Six changes in the lake level occurred from marine isotope stage (MIS) 7 to (MIS) 5. Three major high stands occurred in the paleolake at the lowest and middle parts of the sequence. The first high stand was a stepwise transgression between ~240 and ~230 ka., and the second high stand was between ~200 and ~195 ka. The third high stand was characterized by a short transgression at 182 ka. After this stage, the lake receded significantly at 127 and 105 ka, indicating climatic control over the water level changes. In the transition from the Middle to Late Pleistocene, a revival of volcanic activity in the Leşkeri monogenic volcanic mass released volcanic material, affecting sedimentation. Volcanic rocks increase dramatically in the upper section of the fandelta during an interval that coincides with low lake-level fluctuations.

Özet

İç Anadolu Bölgesi’nin Orta Kızılırmak bölümünde bulunan Bor Ovası, Niğde’nin batısına doğru 14 km uzanır. Ovanın güneybatısındaki yelpaze deltası, Keçiboyduran Dağı’nın fay kontrollü eteğinde oluşmuştur. Fan delta, mineralojik içerik ve sık sık değişen fasiyes nedeniyle bir faz sırasında eski bir göl ortamında oluştuğunu göstermektedir. Ayrıca nemli ve kurak iklim koşullarını yansıtan kil mineralleri ve otsu bitkiler göl seviyesindeki değişimleri göstermektedir. Deniz izotop aşaması (MIS) 7’den (MIS) 5’e kadar göl seviyesinde altı kez değişiklik meydana geldiği anlaşılmaktadır. İstifin en alt ve orta kısımlarında eski göl ortamında üç büyük yüksek basamak meydana gelmiştir. İlk yüksek basamak, ~240 ile ~230 ka arasında ve İkinci yüksek basamak ~200 ile ~195 ka arasındadır. Üçüncü yüksek basamak 182 ka’da görülmektedir. Bu aşamadan sonra göl 127 ka ve 105 ka da önemli ölçüde gerilemiştir. Bu durum su seviyesi değişiklikleri üzerinde iklim kontrolünün olduğunu göstermektedir. Ayrıca Orta Pleyistosen’den Geç Pleyistosen’e geçişte, Leşkeri volkanik kütlesinden çıkan materyal sedimantasyona etki etmiştir. Bu nedenle volkanik kayaçlar, düşük göl seviyesi dalgalanmalarına denk gelen bir aralıkta fan deltanın üst kesiminde önemli ölçüde artar.
