Abstract For many decades, the Red Sea has attracted the attention of many scientists. Badr and Grossland (1939) described the reefal formations and outlinedthe topographic nature of the Red Sea. Subsequent studies have been made by Shukri and Higazy (1944 a,b); Mohamed (1949), Said (1950, 1951 & 1990)and Shukri (1953). Recent studies have been confined to the Red Sea coralreefs and their depositional environments (Friedman, 1959, 1968; Loya andSlobodkin, 1971). In his study, Aylon (1976) divided the western coast of theGulf of Aqaba according to heavy minerals distribution into four provinces. The origin, genesis and nature of the reef sediments of the northern Red Sea wasstudied by EI-SaI1U11ak(1992). Geochemical study of the bottom and beach sediments of Jubal strait, Red Sea, was made by El-Askry et al. (1988). Sedimentological and mineralogical compositions of unconsolidated sediments in the Jubal strait region were studied by Moussa et al. (1991). Geomorphologically, both alms of the Red Sea; Gulf of Aqaba and Gulf of Suez, are relatively small marine elongated embayments bifurcating from the northem end of the Red Sea enclosing Sinai Peninsula. The interior of the Gulf of Aqaba is occupied by three Deeps and elongated basins. TI1e basins are striking N (200 - 250 ) E and separated by low sills. Generally the Gulf is divided into three distinct parts. The northern part has a relatively simple bathymetry, and is dominated by the flat bottomed Elate Deep. This Deep is of about 50 km length, 3-8 km width and is considered as the largest Deep in the Gulf, although it is the shallowest one (900 m depth). The central part of the Gulf is of about 35 km length and 6 km width. This part includes the deepest regions in the Gulf; the Aragonise (1850 111depth). |
