摘要

This study investigates the geochemistry of Al-Lith coastal sediments using the spatial distributions of grain size and ofsome environmentally sensitive chemical elements and their geochemical zonation. The results show that the sediments arecharacterized by a wide range of grain sizes and consist mainly of terrigenous and biogenic carbonate materials. Statisticalanalyses of the data show three main factors controlling the distribution of elements. They are grain size, mineralogicalcomposition, and organic carbon content. According to the elemental associations and distributions, four geochemical zonesare identified. Zones A and C are dominated by carbonate-rich sediments and high concentrations of Ca and Sr and lesserMg. Zones B and D consist of sandy and muddy sediments with low carbonate contents and significant concentrations ofFe, Al, Mn, Ni, Co, Zn, Cr, and Cu. Elements show differences in partitioning trends, indicating varied elemental behaviorswith environmental and sedimentological significance.
