Magnetic susceptibility is largely depending to mineralogy of materials particularly to Fe- bearing minerals. However, some other inherent and non-inherent properties of sediments such as grain size and shape can impact the measures. This property enables us to classify different types of sediments based on their magnetic behavior. The Hassangholi Bay lies in the eastern flank of the Caspian Sea where the region has been influenced by the level changes. The area receives sediments from different sources with different magnetic properties. Copet Dagh in the east is the main source for detrital carbonate while Alborz Mountain in south could be the main source for Fe bearing minerals. However, the Caspian Sea could bring sediments during sea level rise. This last source could change the magnetic susceptibility behavior of the sediments and could be a potential proxy for tracing the Caspian Sea level fluctuations. This paper tries to make a correlation between the magnetic susceptibility and sea level curves in the eastern flank of the Caspian Sea
