“…The lower tidal flat is disturbed by active crab burrowing . Most of the previous studies carried out in the study area focused on the foraminiferal distribution and the textural, mineralogical, and geochemical characteristics of the Al-Kharrar Lagoon bottom sediments (e.g., Abou-Ouf, 1996;Al-Washmi, 1999;Basaham, 2008;Basaham et al, 2015;Al-Dubai et al, 2017;Hariri and Abu-Zied, 2018). The subsurface stratigraphy of the eastern and southern coastal plain of the Al-Kharrar Lagoon was briefly described (Behairy et al, 1991;El Abd and Awad, 1991).…”

“…The lagoons were previously studied for their sedimentological and micropaleontological attributes [15][16][17][18][19]. The geochemistry of the environmentally sensitive elements in the bottom sediments of the two lagoons were involved to establish a geochemical background for the Red Sea coastal lagoons [11].…”

“…The present study is a part of an ongoing research project on the geochemistry of the Red Sea coastal lagoons. Basaham et al [11] published a part of the data to establish a geochemical background for the Red Sea coastal lagoon sediments. The aims of the present study are to map the elemental distribution in the carbonate dominated Al-Shuaiba and Al-Mejarma lagoons to determine the sources and pathways of the elements in the lagoons and to understand the controlling factors on their spatial distribution.…”

Geochemical and mineralogical analyses of bottom sediments collected from Al-Shuaiba (SHL) and Al-Mejarma (MJL) coastal lagoons, Red Sea were carried out. Mineralogically, the sediments consist mainly of carbonate minerals particularly aragonite, high and low Mg-calcite and traces of dolomite admixed with non-carbonate minerals including quartz, k-feldspars, plagioclase and traces of amphiboles, mica and clay minerals. The spatial distribution of major and trace elements at the bottom of the lagoons indicates two groups of elements. The first, less significant, is of terrigenous origin concentrates mainly in the shoreward direction. This group includes the silicates (Al2O3-Fe2O3-SiO2), Feldspars (K2O-Rb-Ba) and heavy minerals (V-Cr-Zr, TiO2-Y-Nb) related elements. The second most dominant group is the carbonate related elements (CaO-Sr) that concentrates in the seaward direction. The two lagoons are not affected by urbanization or anthropogenic impact, and hence the siliciclastic elements are related to the terrigenous influx mainly by aeolian transportation. The carbonate related elements are mainly of biogenic origin related to calcareous skeletal remains. The elemental distribution in the bottom sediments of the MJL is more homogeneous than those in the SHL reflecting the bottom conditions that are mainly controlled by lagoon morphology, hydrodynamic and the water circulation between the lagoon and the sea. Geochemical data show no obvious enrichment of Al-normalized redox-sensitive trace elements V and Cr suggesting that there is no variation in the bottom redox conditions in contrast with other previous studies. The information in this work is an important tool for biogeochemical and biological research projects in the Red Sea coastal lagoons.
