Bu çalışmada, Orta Anadolu Volkanik Bölgesi (OAVB) içerisinde yer alan Salanda Fay Zonu (SFZ) ile ilişkili Balkayası ve Sarıhıdır traverten oluşumlarının U-serisi yaşları küresel ve bölgesel paleoiklim kayıtları ile karşılaştırılmıştır. İnceleme alanında yüzeyleyen travertenlerin yaşları, U serisi yaş analizi verilerine göre 9-55 bin yıl arasında değiştiği gözlenmiştir. Bunun yanında δ13CPDB 10.97 ile 13.16 arasında ve δ18OPDB değerleri ise -12.01 ile -8.66 arasında belirlenmiştir. Travertenlerden elde edilen yaş tarihleri, çok soğuk (kuru) dönemleri temsil eden MIS (deniz izotop tabakası) 3'te ve MIS 2'de ve MIS 1'in başlangıç periyodunda oluştuklarını ortaya koymaktadır. Traverten oluşumlarından elde edilen yaş verileriyle bağlantılı olarak, SFZ üzerindeki doğrultu atımlı geçişin Geç Pleyistosen'e kadar uzandığı yorumlanmaktadır.
