“…The stacking pattern of sedimentary beds shows the progradation of of intertidal to supratidal/sabkha deposits as the Wadi Ash Shaqah al Yamaniyah delta as sea level fell during the Late Holocene. Similar prograding systems were recorded in the sedimentary records of Al-Kharrar Lagoon coastal sediments by Ghandour and Haredy (2019). The decrease of carbonate and increase of siliciclastic materials indicate the influence of the terrestrial sediment influx.…”

“…A similar feature was seen in the Dumaygh Lagoon north of Al-Wajh, Saudi Arabia, where the vertical stacking of intertidal and supratidal facies above a shallow subtidal facies reflects a progradational sequence that may relate to the late Holocene relative sea level fall (Ghandour et al, 2020). These progradational sequence correspond to the progradation seen at Al Kharrar Lagoon (Bantan et al, 2019;Ghandour and Haredy, 2019) and to the occurrences of beach rock up to 1.2 m above MSL formed near Rabigh during the late Holocene phase of falling sea level (Manaa, 2016).…”

“…Similar features of deposits are recorded in several coastal sedimentary cores (Boski et al, 2015;Kumar et al, 2018) and are interpreted as representing a fluvial depositional environment. Likewise, the dominance of terrestrial sediments at the base of sedimentary cores retrieved from intertidal deposits in Al-Kharar Lagoon are explained by Bantan et al (2019) and Ghandour and Haredy (2019) as an increased influx of terrestrial sediments. The thin layers of gray to brownish-gray argillaceous sand indicate a transition of depositional conditions to a supratidal under the initial influence of rising sea level on the very low gradient topography.…”

“…The central and southern Saudi coast has been tectonically stable during the Holocene (Manaa et al, 2016) and changes in accommodation space reflect eustatic changes in sea level (Ghandour and Haredy, 2019;Bantan et al, 2020;Ghandour et al, 2020). These changes vary along the Red Sea coast in the timing and the spatial distribution (Al-Mikhlafi et al, 2021).…”

“…Most of these latter studies dealt with past environmental changes based on micropaleontology (Abu-Zied and Bantan, 2013Bantan, , 2015Pavlopoulos et al, 2018;Bantan et al, 2019), and coral reefs (Moustafa et al, 2000;Manaa et al, 2016). Only a few studies integrated sedimentary characteristics with other paleoenvironmental proxies (Hein et al, 2011;Bantan et al, 2019;Ghandour and Haredy, 2019). These studies mentioned that the mid to Late Holocene climate ranged from humid at the end of the mid-Holocene to fluctuations between semi-arid and arid during the Late Holocene.…”

Late Quaternary paleoenvironments are of particular interest to understand how the Earth System’s climate will respond to the undramatic changes during this period, compared with the broader glacial-interglacial variations. In this study, a shallow sediment core (2.84 m long) retrieved from the Red Sea coastal zone in northern Ghubbat al Mahasin, south of Al-Lith, Saudi Arabia, is used to reconstruct the mid-Late Holocene paleoenvironments and sea level based on a multiproxy approach. Remote sensing data, sedimentary facies, benthic foraminiferal assemblages, δ18O and δ13C stable isotopes, elemental composition and 14C dating were utilized. The stratigraphy of the core shows three distinctive depositional units. The basal pre 6000 year BP unit consists of unfossiliferous fine to medium sand sharply overlain by black carbonaceous mud and peat, suggesting deposition in a coastal/flood plain under a warm and humid climate. The middle unit (6000-3700 year BP) records the start and end of the marine transgression in this area. It consists of gray argillaceous sand containing bivalve and gastropod shell fragments and a benthic foraminiferal assemblage attesting a lagoonal or quiet shallow marine environment. The upper unit (<3700 year BP) consists of unfossiliferous yellowish-brown argillaceous fine-grained sands deposited on an intertidal flat. Both middle-and upper-units stack in a regressive shallowing upward pattern although they may be separated by a hiatus. The overall regressive facies and the stable isotopic data are consistent with a late Holocene sea-level fall and a change to a more arid climate.
