One of the effective method in identification of sediment sources and erosion is recognition of erodible formation in drainage basin witch can be performed by using geochemical tracing method. In this research, due to high sediment production of south west part of Zarivar Lake Drainage Basin presence of small dams in this part, fine sediment sample were investigated using geochemical method. The percentage of contribution of lithological units and formation in fine-grained sediment portion was determined and erodibility map of geological materials was prepared using this method. Geochemical studies showed that SK-Hf lithological unit consisting of skarn and small hornfels with relative importance of 82.54% has the highest amount of sediment yield potential in the studied area and Qla lithological unit with relative importance of 8.37% has the lowest of sediment yield potential.
