Paleolimnology of Ercek Lake bottom sediments

The aim of this thesis is to study the paleolimnological properties of the bottom sediments of Lake Erçek and to correlate the data with the pas climatic changes. For this purpose within the scope of TUBITAK Project no. 114Y825, a sediment core was taken from Lake Erçek and evaluated with this aim. Chronological (137Cs-210Pb, varve counting), sedimentological (magnetic sensitivity, density, thin section and grain size) and geochemical (TOC-TIC) were performed on this short core. According to the chronological analysis, the age obtained throghout the core covered the last 750 years. Sedimentological and geochemical analysis results are correlated and the supported each other. Accoording to the data obtained during the las 750 years five different periods have been identified between 1260-1405 AD, 1405-1565 AD, 1656-1882 AD, 1882-1958 AD and 1958-2015 AD in different climatic conditions.
