Geochemical and sedimentary characteristics of the coast sediments between Lipar and Pozm Gulf in Southeastern of Iran have been investigated by taking 23 sediment samples. Samples of sediment were collected using of coring Euger in the tidal zones. On the basis of this research, 12 sedimentary types are identified that the dominant type are muddy sand, sand and sandy mud. Clastic components in sedimentary types, a collection of minerals, quartz, calcite, feldspar, iron oxides, clay minerals and are Ooid. Non-clastic components include fossil shell fragments. Geochemical study of coast sediments such as correlation coefficient, cluster diagram and factor analysis indicate four classification of elements enrichment base on source. (I) Elements such as Cr, Zn, Mn, Co, Mg, Ti, Fe, Sc and Ba, that the highest correlation and the origin of outside the basin (Geogenetic). (II) This group of chemical elements are biological in origin (Biogenetic) and include Sr, Ca and P. (III) The third group of this elements are Pb and Cu that anthropogenic source and known as environmental pollutants. (IV) Finally, the fourth group includes elements Na and Li are related to evaporate sediments.
