Abstract: 

Introduction: Lakes are very interesting sedimentary environments for study of ancient climate changes in the environments and lake level changes. Lake Zeribar is situated in the province of Kurdistan, in the Zagros Mountains in three kilometers north-west of Marivan. The main purpose of this research is to study grain-size sediments accumulated in Zeribar lakes in order to check the water level fluctuations, climatic and environmental changes during the Holocene. Grain-size of the lake sediments is mainly controlled by the distance of the core site from the shoreline, the kinetic energy of the lake circulation and the source of the sediments (Lerman, 1978). The sediments sorting principle states that the grain size of lake sediments becomes finer and finer from the shore to the center, and sediment belts of different grain-size can be distinguished. Lake Zeribar sediments, providing a record of climatic variations more than 40, 000 years long, have been the subject of multidisciplinary investigations reported in several publications (among others: plant macrofossils by Wasylikowa, 1967, 2005; diatoms by Snyder et al., 2001; stable isotopes by Stevens et al., 2001). However, sediments of the lake have not yet been analyzed for grain-size, whereas it could reveal important information about the lake history and sedimentary process-geomorphology.
