“…The heavy metal pollution in marine sediments, beaches, and seashells along the Red Sea coast was investigated using numerous authors (Abdelkader et al, 2018 ; Attia & Ghrefat, 2013 ; El-Metwally et al, 2019 ; El-Sorogy et al, 2012 ; Madkour, 2005 ; Madkour et al, 2012 ; Mansour et al, 2011 ; Philobbos et al, 1983 ; Ramadan & Zaid, 2013 ; Redwan & Rammlmair, 2017 ; Salem et al, 2014 ; Temraz & El-Sawey, 2017 ). The overall contamination came from lithologic nature and anthropogenic activities such as land filling, oil pollution, and utilizing antifouling and anticorrosive paints from the fishing and shipping processes of phosphate ore.…”

Globally, the environmental contamination of stream sediments due to geogenic and anthropogenic sources is of growing concern. In this study, the heavy metals (Cd, Co, Cr, Cu, Ni, Pb, and Zn) in 22 superficial sediments in Wadi Asal, Red Sea, Egypt, were explored to assess sediment sources, the mobility of chemical species, and the degree of contamination in sediments. Therefore, the total heavy metal values in the fine fraction (< 63 μm), a five-step sequential extraction on selective samples, risk assessment, and principal component analysis (PCA) were applied. The mobility of heavy metals in Wadi Asal sediments, according to non-residual fraction percent, declines in the following order: Cd (90.9%) > Pb (85.2%) > Co (84.4%) > Cu (80.8%) > Zn (75.9%) > Ni (48.4%) > Cr (39.6%); indicating the high mobility of Cd, Zn, Pb, Cu, and Co. The mean metal contamination factor (CF) order is Cd (10.96) > Ni (3.91) > Cr (2.77) > Zn (2.18) > Pb (2.10) > Co (1.12) > Cu (0.70). The Geo-accumulation Index (Igeo) is decreased in the following order: Cd (2.19) > Ni (0.78) > Cr (0.55) > Zn (0.44) > Pb (0.42) > Co (0.22) > Cu (0.14). The risk assessment code (RAC) revealed very high to high risk for Cd, Co, and Pb. The results pointed out that the metals Cr, Co, Cu, and Ni are from geogenic sources, while Zn, Cd, and Pb are from anthropogenic sources due to Pb–Zn mining activities. Based on the threshold effect level (TEL), Cd, Cr, Ni, and Pb have adverse effects on living organisms. According to these findings, the area along Wadi Asal and the downstream regions on the beach are highly polluted and heavy metal monitoring in sediments and aquatic organisms is recommended.

“…The concentration of barium in beach sediments between Marsa Alam and Shuqeir (El-Mamoney and Rifaat, 2001), the environmental characterization and radio-ecological impacts of non-nuclear industries (El Mamoney and Khater, 2004), the geochemistry and sedimentology of core sediments and the influence of human activities (Ahmed, 2005), the provenance of recent sediments along the Red Sea coast (Ramadan and Zaid 2016) and the provenance of recent sediments and the radiological aspects of water, soil and shore sediments resources (Arafat et al, 2017) were studied. Grain size parameters of the study beach sediments between Marsa Alam and Wadi El-Jimal is presented here as an approach to evaluate the textural parameters and the heavy mineral concentrations to understand the mineral distribution in relation to source rocks.…”

“…Generally, the chemical composition of sediments can be used to draw a clear picture indicating the characteristics of the sediment source (Roser & Korsch, ). For example, the chemical composition of sedimentary rocks has been used to infer the potential provenance, constrain the tectonic settings of sedimentary basins, and reveal possible paleosedimentary conditions (Armstrong‐Altrin et al, ; Cullers, ; Liu et al, ; Ramadan & Zaid, ; Young, Pitawala, & Ishiga, ; Zhang, Wang, Yan, & Wan, ). Recently, sedimentary geochemistry has been used to study orogenic belts (Kasanzu, Maboko, & Manya, ; Lambeck, Huston, & Maidment, ; Long, Sun, & Yuan, ).…”

“…However, the sediments implying important information about the growth history between the basin and the orogenic belts may provide an effective method to reveal the covered history (Hofmann, ; McLennan, Hemming, McDaniel, & Hanson, ; Mu, Wang, & Wang, ; Rudnick & Gao, ; Xu, Du, & Yang, ; Yan, Xiao, Liu, et al, ). Many scholars employed lithogeochemistry, petrography, heavy mineral compositions, and geochronology of ancient clastic deposits to infer the provenance and the tectonic settings (Bhatia, ; Bock, McLennan, & Hanson, ; Herron, ; Ramadan & Zaid, ).…”

Provenance and tectonic setting of the Early and Middle Devonian Xueshan Formation, the North Qilian Belt, China

The North Qilian orogenic belt is the key in the exploration of the formation and assembly of Asia. The Early–Middle Devonian Xueshan Formation, which is deposited in the north area of North Qilian Orogenic Belt, is the most important for revealing the evolution basin–mountain transition of the North Qilian Belt. In order to reveal the tectonic evolution of the central orogenic belt in China and Paleozoic global plate reconstruction, it is necessary to perform provenance analysis of the Xueshan Formation. Eighteen samples were collected from Yumen and Yongchang profiles in the west of North Qilian Belt (WN), and 16 samples were obtained from Gulang and Jingtai profiles in the east of North Qilian Belt (EN). The compositions of clastic conglomerates and the sandstones suggested that felsic volcanic was the main source of the WN Xueshan Formation deposits and that the sedimentary and metamorphic rocks were the main source of the EN sediments. According to major geochemistry indexes, such as Al2O3/SiO2 ratio ranging from 0.08 to 0.37 and the chemical index of alteration less than 80, the source rocks were moderately weathered and of moderately matured. The samples from the EN were relatively enriched in Cr, Ni, Sc, and V elements and depleted in Hf element. However, those from the WN were enriched in Hf without the enrichment of Cr, Ni, Sc, or V. The samples from WN showed a strong negative Eu anomaly, but the samples from EN showed a weak negative Eu anomaly or a positive Eu anomaly. All the above geochemical characteristics suggested the prominent input of felsic clasts with granitic rocks into the WN. Meanwhile, the discrimination diagrams of trace elements implied that WN rocks were derived from continental island arc and that the EN rocks were derived from orogenic belt and the passive continental margin. The North China Plate subducted southwards and formed subduction‐related arc magmatism along the southern margin of the North Qilian Terrane during the Early–Middle Devonian. In conclusion, the WN is a fore‐arc basin, but EN is a foreland basin.
