The Persian Gulf is the most important aquatic ecosystem in West Asia and the Middle East region. The beach of this Gulf in Bushehr port is one of the most important recreational and commercial beaches in the country. In order to investigate the sedimentology and geochemistry of the Persian Gulf coastline deposits in the area of this port, 28 surface sediment samples were collected and grain size analysis and XRF geochemical analysis was done. The results showed that the sediments of this beach were sand with a small amount of gravel, which indicated continuous energy in this beach and the washing of mud particles. The geochemical results showed that the highest concentration of oxides were SiO2 and Cao. Investigating the source rock and tectonic position of these deposits showed the primary composition of lite arenite and sublite arenite and the tectonic position of the active continental margin. Hydraulic melting also indicated the immature to medium maturity composition of these sediments, which indicate semi-arid weather conditions with medium chemical maturity. In general, the similarity of the tectonic conditions and ancient climate of these deposits with the Zagros sequence indicated the existence of Zagros as the main source of these deposits.
