Abstract

Gölsel çökel istifler geçmişte olmuş iklimsel,
tektonik, volkanik, su seviyesi değişimleri ve sedimantasyon hızı gibi
değişikliklerin kayıtlarının tutulduğu önemli arşivlerdir ve Van Gölü dip
çökelleri karasal olarak uzun bir geçmişi simgelemesi nedeni ile bu tip
çalışmalar için karakteristik bir örneği temsil etmektedir. Gölsel çökel
istifler farklı alanlarda çalışılırken kronolojik olarak yaşlandırılması
gerekmektedir. Bu açıdan farklı birçok yaşlandırma metodu mevcuttur. Bu çalışma
kapsamında, Van Gölü’nün farklı fizyografik bölgelerinden alınan altı adet kısa
karot üzerinde dengeüstü 210Pb aktiviteleri hesaplanmış ve CRS
modeline göre ortalama sedimantasyon hızı belirlenmiştir. 137Cs
aktivitesi bu çalışma kapsamında kronostratigrafik belirteç (1963, 1986) olarak
kabul edilmiş ve hesaplanan sedimantasyon oranları ile uyumlu bulunmuştur. Elde
edilen sedimantasyon oranları 0.5 mm/yıl ile 1.3 mm/yıl arasında değişmektedir.  Sedimantasyon oranlarındaki farklılığın
sadece su derinliği ve drenaj havzası kontrollü olmadığı bununla birlikte göl
tabanındaki morfolojik unsurların kontrolü altında olduğu ortaya
konmuştur.
