“…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). Phosphorite is a vital resource that is essential for agriculture, as it is a primary source of phosphorus for fertilizers (Gadri et al 2015;Rais et al 2017;Dahoua et al 2018;Anis et al 2019; Barra et al 2019;Zhang et al 2019).…”

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.

Understanding erosion patterns and drainage conditions is crucial for optimizing agricultural productivity and for addressing the challenges of wastewater treatment. To achieve this, we employed a comprehensive approach, combining the morphometric method with weighted sum and Geospatial techniques. Utilizing a 30-m-wide Digital Elevation Model (DEM), specifically the Aster DEM, and leveraging ArcGIS software, we meticulously delineated drainage systems and watershed boundaries. Through the application of standard formulas, we calculated areal, linear, and relief parameters to effectively rank and prioritize the sub-watersheds. Our examination led to the calculation of a composite factor, determined through an assessment of 18 morphometric criteria employing a weighted summation approach for each subcatchment. The outcomes of our research unveiled a wide range of compound factor values, spanning from − 0.128 to 9.28. This study underscores the pivotal role of the minimal compound factor value in determining the sustainability of sub-watersheds. As a practical illustration, we found that Basin 3 exhibited superior sustainability when compared to Basin 4, primarily attributable to soil erosion issues in the latter. Sub-watersheds were additionally grouped into classes according to their composite factor values, commonly characterized as highly favorable, favorable, intermediate, or unfavorable, providing insights into their vulnerability to erosion. Moreover, our research pinpointed Basin 4 and Basin 7 as highly vulner able to soil erosion, with a combined area of 294.9 km2. The implications for wastewater treatment are significant in these areas, as proper water and soil conservation techniques are imperative not only for the sustainable management of these lands but also for mitigating the environmental impact of the wastewater treatment process.
