“…It is the cumulative impact on the water and on the soil. These higher values are mainly recorded in specific areas such as the cities of Tebessa, Souk Ahras, Annaba, Jendouba, El Kef, and Beja, which are associated with the mining and ore industry and also with the presence of the diapiric and the metamorphic rocks in the high altitude (1,500 -2,800 m) [18,19,20,21,22].…”

Natural radioactivity of 238U, 232Th and 40K for water and sediment samples collected from Sidi Salem dam (Tunisia) and Aïn Dalia dam (Algeria) were measured using TERRA detector of rays (gamma, beta, and alpha), Gamma-ray spectrometry and atomic absorption spectroscopy were used to analyze the levels of radionuclides and heavy metals, respectively. Heavy metals (Fe, Pb, Zn, Ni, Cu, Cr and Cd) and associated health risks in surface water and sediment of dams have been investigated in this study. The mean activity concentrations in the water samples were 1.72±0.01, 0.068±0.01 and 94.6±1.04 Bql-1 for 238U, 232Th and 40K respectively (Tunisia dam) and were 1.9± 0.24, 0.09±0.01 and 131.43±1.03 Bql-1 for 238U, 232Th and 40K respectively (Algeria dam). The mean activity concentration of 238U, 232Th and 40K measured in the sediment samples were 2.67±0.01, 0.18±0.012 and 197.87±2.01 Bqkg-1 respectively (Tunisian dam) and were 4.34±0.05, 0.27±0.05 and 287.61±3.34 Bqkg-1 respectively (Algeria dam). The activity concentration of 40K was higher than that of 238U and 232Th for the water and sediment samples. The mean activity concentrations follow the order 40K &gt; 238U &gt; 232Th. The mean concentrations of the heavy metals decreased in this order Fe &gt; Pb &gt; Zn &gt; Ni &gt; Cr &gt; Cu &gt; Cd. All measured activity concentrations and estimated radiological parameters were below world permissible limit values. Therefore, there may be no serious immediate radiological health burden on the environment and the people using the damage.

“…The sustainability of modern human civilization depends heavily on the availability and management of Earth's natural resources (Kallel et al 2017;Besser et al 2021;Ncibi et al 2021;Bagwan et al 2023). Nearly every industry requires minerals as essential inputs for their operations (Zeqiri et al 2019;Fredj et al 2020;Kerbati et al 2020;Zerzour et al 2020Zerzour et al , 2021. Valuable chemical elements and useful minerals can be found in rocks, soils, and water (Nekkoub et al 2020;Benmarce et al 2021;Orabi et al 2023;Sankar et al 2023).…”

The characterization of phosphorite features within specific North African sedimentary series remains incomplete. Hence, the primary aim of this research is to determine the composition of powder patterns and phosphatic allochem fragments within the Jebel Dhyr syncline, situated in northeastern Algeria. By focusing on this region, the study endeavors to investigate the mineralogical properties and geochemical aspects of Paleocene-Eocene phosphorites in the broader context of North Africa. The methodology employed encompasses geological, petrographic, geochemical, and mineralogical analyses of the rocks. To achieve this objective, we have employed various techniques including thin section analysis, atomic absorption spectrometry, and X-ray diffraction (XRD). The geological section across the Jebel Dhyr area has revealed a succession of horizontally layered rocks. These rocks consist of eight prominent phosphorite layers interspersed with carbonate formations. Additionally, occasional thin layers of flint can be observed within these carbonate layers. XRD analysis of the whole rock established the presence of apatite group minerals such as hydroxylapatite, fluroapatite, francolite, and dahllite. Other minerals identified include carbonates, quartz, zeolites, feldspar, clays, sulphides, and gypsum. XRD recordings on the phosphatic allochem grains (pellets, coprolites, intraclasts, and shark teeth) identified different mineral phases, with coprolites and pellets showing hydroxylapatite and fluorapatite, sometimes associated with dahllite, while granules of different forms revealed hydroxylapatite associated with fluorapatite or francolite. Teeth from the Jebel Dhyr phosphate beam showed the systematic presence of fluorapatite. This study provides valuable information for the comprehensive utilization of phosphorus resources in the Algeria-Tunisia border.

“…They play essential roles in socioeconomic development, industrial processes, manufacturing of modern technologies, and construction of modern transportation systems [2][3][4][5]. A mineral resource is commonly defined as "a concentration of naturally occurring material in or on the Earth's crust in such form and amount that economic extraction of a commodity from the concentration is currently or potentially feasible" [6][7][8]. Evaluation of these resources (mineral resource estimation) is a crucial and challenging task in every mineral exploration and mining project, irrespective of size, commodity, and deposit type [9,10].…”

“…Mineral resources are subdivided into inferred, indicated, and measured categories based on increasing geological confidence and knowledge, as illustrated in Figure 1 [8]. The estimation of a mineral resource is followed by a mineral reserve estimation, which is carried out to determine the tonnage and average grade of a mineral deposit that is economically and technologically feasible to mine [12].…”

Mineral resource estimation involves the determination of the grade and tonnage of a mineral deposit based on its geological characteristics using various estimation methods. Conventional estimation methods, such as geometric and geostatistical techniques, remain the most widely used methods for resource estimation. However, recent advances in computer algorithms have allowed researchers to explore the potential of machine learning techniques in mineral resource estimation. This study presents a comprehensive review of papers that have employed machine learning to estimate mineral resources. The review covers popular machine learning techniques and their implementation and limitations. Papers that performed a comparative analysis of both conventional and machine learning techniques were also considered. The literature shows that the machine learning models can accommodate several geological parameters and effectively approximate complex nonlinear relationships among them, exhibiting superior performance over the conventional techniques.
