Environmental Applications of Marine Foraminifera and Ostracoda Assemblage in Faw Town, South of Iraq

A study of marine foraminifera and ostracoda assemblages from Faw Town, southern Iraq, reveals distinct depth-related patterns in species distribution along the Arabian Gulf. Analysis of 15 surface and subsurface sediment samples (collected to a depth of 21 meters) identified 24 ostracod species across 21 genera and 50 foraminifera species from 19 genera. Cypreidis, Tanella, Actinocythereis, and Neocytheromorpha dominated shallow depths, while Ammonia, Elphidium, Quingloculina, and Spiroloculina increased with depth, indicating transitions between low-salinity tidal environments and higher-salinity marine conditions. The research highlights the ecological indicators of these microfossils in coastal sediment analysis, offering insights into environmental variability, sea-level changes, and sediment composition.
