“…Dawood et al (2013) applied whole rock U/Th dating methodology to the coral terrace in the Rabigh area of Saudi Arabia, resulting in ages of 128 ± 0.2 ka at about 3.5 m, 212 ± 1 ka at about 2.5 m, and 235 ± 1 ka at about 0.9 m apsl in the reef terrace. They suggested that deposition occurred during periods of higher sea levels linked to MIS 5 and 7.…”

“…The age of the upper part of the reef terrace reflects MIS 5e of the last interglacial and is consistent with previously mentioned references and the new data presented here. The 212 ka sample from Rabigh provided by Dawood et al (2013) is shown coming from the upper MIS 5e terrace in their figure 2 but from the lower terrace in their figure 3. However our terrace mapping suggests that exposures 100 m inland show that there is only a single terrace at Rabigh and the junction between their terraces actually represents a notch cut during the Holocene high-stand of sea level with the inclusion of beach rock both in this upper notch and in areas between the cliff exposures.…”

“…Dawood et al (2013) applied the alpha-counting U/Th dating method to three whole rock samples within a single terrace 3-4 m high in the Rabigh area, resulting in ages ranging from 235 ± 1 to 128 ± 0.2 ka while Bantan et al (2015) dated a 5 m high reef terrace on the Jeddah coastal plain that revealed a range of Modified from Saifullah (1996) and PERSGA/GEF (2003). ages between 121 and 299 ka representing possible composite MIS 5-MIS 9 reef deposits.…”

Dating Quaternary raised coral terraces along the Saudi Arabian Red Sea coast

Late Pleistocene raised coral reef terraces form extensive outcrops up to 5 km wide along the Saudi coast. Porites coral were dated using U/Th while clastic sediment from Jeddah was dated using thermoluminescence. The pooled mean age for the coral samples is 121.5 ± 0.2 ka suggesting MIS 5e, even for the uplifted 16-20 m high terrace in the north at Haql. In Jeddah the MIS 5e back-reef succession is overlain by fluvial sediment that gave a TL age of 66 ± 13 ka. The structure and faunal composition of the coral terraces suggests that they accumulated in broad shallow embayments following the last interglacial transgression. The consistent elevation of these terraces suggests that the central and southern Saudi coast has been tectonically stable for at least the past 125,000 years and the coral reef terraces (at 3.5-5.5 m elevation) are consistent with the MIS 5e sea level high-stand that peaked at 6-9 m above present sea level. The Saudi coastal coral terrace north of Duba shows progressive uplift to 16-20 m near Haql since 108-120 ka as a result of ongoing transform faulting in the Gulf of Aqaba.

“…Uplifted marine strata and laterite deposits are suggestive of a low‐lying landscape between 50 and 30 Ma. At the coastline, radiometric dating of emergent Plio‐Pleistocene marine terraces implies an uplift rate of 0.02 ±0.01 mm yr −1 [ Dawood et al ., ]. Finally, thermochronometric analyses suggest that rapid cooling and denudation started at 20–25 Ma [ Bohannon et al ., ].…”

It is generally accepted that the Arabian Peninsula has been uplifted by subcrustal processes.Positive residual depth anomalies from oceanic crust in the Red Sea and in the Gulf of Aden suggest that a region surrounding this peninsula is dynamically supported. Admittance calculations, surface wave tomography studies, and receiver function analyses all imply that regional topography is generated and maintained by some combination of mantle convective circulation and lithospheric thickness changes. Despite these significant advances, the spatial and temporal uplift rate history of the Arabian Peninsula is not well known. Here we show that a regional uplift rate history can be obtained by jointly inverting 225 longitudinal river profiles that drain this peninsula. Our strategy assumes that shapes of individual river profiles are controlled by uplift rate history and moderated by erosional processes. We used local measurements of incision rate to calibrate the relevant erosional parameters. In our inverse algorithm, uplift rate is permitted to vary smoothly as a function of space and time but upstream drainage area remains invariant. We also assume that knickzone migration is not lithologically controlled. Implications of these important assumptions have been investigated. Our results suggest that the Arabian Peninsula underwent two phases of asymmetric uplift during the last 20-30 Ma at rates of 0.05-0.1 mm a 21 . The southwestern flank of the peninsula has been uplifted by 1.5-2.5 km. Regional stratigraphic constraints, the age and composition of volcanism, paleosol formation, incised peneplains, emergent marine terraces, and thermochronometric measurements corroborate our calculated patterns of uplift. Progressive development of three domal swells along the western margin of the peninsula is consistent with localized upwelling of hot asthenospheric mantle.

Biofacies and diagenetic alterations of the Pleistocene coral reefs, northwest Red Sea coast, Saudi Arabia

et al. 2019

Middle to Late Pleistocene coral reefs stretch in three discontinuously elevated units above the present sea level between Duba and Sharma along the Red Sea coast, northwest Saudi Arabia. They correspond to MIS 5, MIS 7, and MIS 9 of the deep sea cores. Each unit exhibits prominent terraces as a result of the onlap during different sea levels, erosion during transgression, and tectonic uplift. Framestones, bafflestones, bindstones, packstones, grainstones and floatstones of coral, algal, and other bioclasts are the main microfacies types recorded from these reefal units and their internal sediment. The lower and the upper units exhibited a vertical pattern of a transgressive sequence, starting at the base with a coral assemblage of coral rock zone and graded into the upper reef slope community at the top, while the middle one exhibited a regressive sequence. Corals progressively changed from aragonite in the lower unit to calcite in the upper one by meteoric leaching of the trabeculae, and the cements changed from marine aragonitic needles and peloidal Mg‐calcite in the lower unit to blocky and dog teeth cements and silica in the middle and upper units. The gravel lenses within coral colonies of the upper unit with plagioclase, epidote, and fractured quartz grains are attributed to a granitic province from the hinterland mountains, driven to the reef during rainy periods.
