“…Dóniz-Páez (2015) found that sometimes volcanic cones are composed of pyroclastic rocks such as scoria, ash, and bombs, without a visible crater. Jabal Kudumbul Island is controlled by multiple complex geological factors operating on a large scale during the Pleistocene along the southern Red Sea coast, accompanied by widespread volcanic activity occupying the NW-trending main tectonic zones (Jado and Zotl, 1984; Prinz, 1984). The age of the basalt flow rocks in the Al Birk basalts defines an older group dated along the coastal plain as 11.8 ± 1.5 Ma and a younger group of basaltic flow with ages ranging from 0.3 and 5.0 Ma (Coleman et al ., 1977; Prinz, 1984).…”

“…This volcanic field has resulted in rift shoulder uplift, basin subsidence, and deposition of shallow to deep marine facies (As-Saruri, Sorkhabi, and Baraba, 2010;Coleman et al, 1977;Nabhan and Yang, 2018;Prinz, 1984). In the Paleogene and Neogene periods, tectonic movements along the southern Red Sea coast were accompanied by widespread volcanic activity, which resulted in layered gabbro, granophyre, and rhyolitic dikes occupying the NW-trending faults (Jado and Zotl, 1984). Proterozoic metamorphic and igneous rocks constitute the basement exposed behind the basaltic escarpment farther to the east of the coast (Hadley, 1981).…”

A marine geological survey of the Quaternary volcanic island of Jabal Kudumbul in the rifted southeastern Red Sea in Saudi Arabia has been conducted for the first time. The survey aimed to document sedimentological and geomorphological characteristics from sample collection and interpretation of high-resolution satellite images taken in the last decade. Beach, sand dune, and sand sheet sedimentary facies types were identified. The volcanic mountain in the western zone of the island and the low-lying sandy shorelines in the eastern zone represent the main geomorphic landforms related to wave and current processes in the study area. The volcanic cone showed three volcano-stratigraphic facies units: basalt rocks, phreatomagmatic lapilli tuff, and vesicular basalt/scoria, indicating that they might have been formed during eruption and interaction between rising magma and shallow seas. The coastline constantly changes over time due to longshore processes and spring tides. A suite of complex wind, wave diffraction, longshore current, and biological processes and episodic synrifting in the area played dominant roles in facies and landscape creation and the overall development of Jabal Kudumbul Island. These findings provide important information for future studies on the arid islands in the Red Sea region beyond modern surficial deposits.

“…Its salinity ranges between ~ 36‰ (3.6% on the Practical Salinity Scale or PSU, meaning actual dissolved salts) in the southern region and ~ 41‰ (4.0% PSU) in the northern region. The world average is ~ 35‰ or 3.5% PSU [26]. Mangroves, seagrasses, coastal vegetation and associated flora, and terrestrial mammals are common around the coastal zones.…”

Palynomorph assemblages and mineral microfossils from five southern Red Sea coastal environments were studied to demonstrate their distribution pattern and suggest their source. The environments studied were 1. mangrove swamp 2. middle Holocene paleochannel 3. algal mat, 4. Sabia Island coral reef, and intertidal zone. The samples studied were from the top 3 cm semi-consolidated sediments from various environments. Standard palynological maceration technique was used to isolate palynomorphs. These sediment samples are mainly clay and fine sand and yielded low numbers but high diversity of palynomorph assemblages. They are grouped into pollen and spores, dinoflagellate cysts, and algal remains, fungal spores, hyphae and fruit bodies, protists, and invertebrates. A few Ascidian and sponge spicules, and phytoliths (mineral microfossils) occur in the Sabia Island coral reef environment. The protists and invertebrate remain include microforaminifera, thecamoebians, tintinnomorphs, crustacean and annelid palynomorphs. The assemblage also includes six form taxa belonging to the form genera Katora and Mangrovia. These palynomorphs belong to both marine and terrestrial environments and are of autochthonous and allochthonous origins. The source and genetic relationship of each palynomorphs is discussed.

“…The Fatimah catchment's entire surface area is approximately 4,650 km 2 , and it almost perfectly parallels the Red Sea from east to west. Jado and Zotl (1984) claimed that following the intense rains that fall on the higher portions of the Arabian Shield, the deeply cut gorges serve as the gathering pathways for greater floods. In the southwest corner of this wadi, these chasms (deep fissures) rise to elevations of more than 2,000 m above sea level.…”

The Wadi Fatimah area suffers from a lack of freshwater resources, so this study aimed to analyze the groundwater in this region and evaluate its quality for irrigation and drinking purposes. Eleven water quality parameters, including pH, total dissolved solids (TDS), Ca2+, HCO−3, NO−3, F−, Cl−, K+, Mg2+, SO2−4, and Na+, were utilized to evaluate the quality of the water and produce a water quality index (WQI). These parameters were measured at 100 different chosen locations. The spatial distribution map revealed that all parameters are high in the southern part except K+. Using the correlation matrix, a high positive correlation is obtained among TDS, Cl−, Mg2+, and Ca2+ in addition to a high correlation among TDS with Cl− and Na+. From PCA analysis, PCA1, PCA2, and PCA3 represent about 52%, 12%, and 10% of all components along the study area, respectively. PCA1 has low variance than PCA2 and PCA3. The majority of the Southern region’s sites went from having extremely poor to poor water classifications and from poor to unsuitable water. However, the center part possesses exceptionally high-quality groundwater. According to the results from the current study’s water quality index, the presence of nitrate and fluoride in the groundwater samples was primarily responsible for their high WQI values. The statistics showed that a higher percentage of the population had poor drinking water due to direct pollutant release, agricultural effects, and excessive groundwater resource use. The study offers a groundwater quality modeling technique that is both affordable and replicable in other areas.
