Abstract :

 

Total of 32 samples that collected from seven marine core sediments in the north and Northwest of Arabian Gulf (between Umm Qasir port to Basrah Oil Port) ( Figure 1) were investigated in this study . Silt and sandysilt are the main textures in the cores sediments of study area with share of sand and siltysand texture in some studied area especially in cores 1 and 6. Mica group minerals ( Biotite and Chlorite), Ultra stable group ( Tourmaline , Zircon, and Rutile) , un– stable group mineral ( Pyroxene,  Augite, and Hornblend) , meta– stable group mineral ( Garnet, Kyanite, Epidote, Staurollite, and Cellestite) and Opaque minerals were the main of heavy minerals. Quartz, Feldspar, Calcite and Gypsum are the main light minerals in the marine core sediments. Montmorillonite– Chlorite, Palygoreskite–Illite, Chlorite, Montmorillonite and Kaolinite are the most of clay minerals component, with share small amount of Illite, and Palygoreskite. Hydraulic sorting mechanisms caused to make some relationship between mineral abundances and sediments texture. SEM mapping for light minerals showed some heavy metals that adsorbed on these minerals such as Cr, Ni, Br, Ge, Pb and Fe, Ta, and Ti elements.
