The studied shales exhibit significant organic matter, with total organic carbon (TOC) between 1 wt % and 12.3 wt %. The Lam and Meem shale facies are also charactersied by hydrogen rich kerogen types II and II/III. The dominance of such hydrogen-rich kerogen was confirmed from the Py-GC and FTIR structures of the kerogen fraction, exhibiting the possibility of producing commercial amounts of paraffinic–naphthenic–aromatic oils with low wax content. The studied shale facies is currently thermally mature, with the Meem shale facies entered the peak-stage of the oil window, based on measured vitrinite reflectance (VRo) values and high oil saturation index (OSI) values. This claim agrees with the bulk kinetic results, which suggest that the commercial amounts of oil can generate by kerogen conversion of up to 50 % during the peak stage of oil window at geological temperature values between 132 °C and 155 °C, consistent with computed vitrinite reflectance values of 0.77–1.07 %Ro. 1-D basin modeling suggests the Meem shale source rock system is more than the Lam shale source rock, entering the main oil generation during the lower Cretaceous to Late Oligocene time, resulting in commercial quantities of oil, having transformation ratio (TR) i.e. up to 55 %. This high maximum oil generation, alongside high brittleness index leads to create non-fabric fracture pores within the Meem shale facies, which may have increased by elevated pressure during the deep burial depths. Therefore, the Meem shale facies is considered for unconventional shale oil reservoir with recommendation of hydraulic fracturing techniques for unconventional production.</div></div>","PeriodicalId":14874,"journal":{"name":"Journal of African Earth Sciences","volume":"233 ","pages":"Article 105848"},"PeriodicalIF":2.2,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145119657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we examine the geological framework alongside the mineralogy and geochemistry of the Tizi-n-Isdid manganese mineralization to provide insights into the interplay between Mn accumulation mechanism during sedimentation, hydrothermal processes, and post-depositional transformations. The Tizi-n-Isdid mineralization is hosted by reddish-brown claystones occurring at the base of the Taroudant Group in the Tabia member, below the Tamjout dolomite. The new stratigraphic framework supports a Lower Cambrian age for the Mn mineralization, estimated at between 529 and 541 Ma. Braunite is the dominant ore-forming mineral alongside piemontite, hollandite, neltnerie, pyrolusite, jacobsite, rhodochrosite and kutnohorite. The gangue consists of claystone fragments, calcite, quartz, and minor barite. The mineralization extends over 6 km in a north-south direction, exhibiting a stratiform and lenticular shape. Three main mineralization facies are identified: massive (F1), banded (dominant) (F2), and brecciated (F3), with thicknesses ranging from a few centimeters to a maximum of 3 m. Geochemical analyses support a hydrothermal Sedex-type origin for the deposit, characterized by exhalative Mn-rich sediments. The Fe/Mn ratios and trace elements indicate that the mineralizing fluids were likely associated with syn-sedimentary hydrothermal activity, possibly linked to rift-related fault systems rather than direct volcanic influence. The deposit has undergone slight metamorphism, as evidenced by the transformation of primary braunite into secondary braunite and piémontite. This model can be applied to other stratiform Mn deposits occurring in the Ouarzazate Manganese Field.</div></div>","PeriodicalId":14874,"journal":{"name":"Journal of African Earth Sciences","volume":"233 ","pages":"Article 105853"},"PeriodicalIF":2.2,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145119659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, their petrographic and geochemical characteristics have not yet been examined. Accordingly, this study aims to reconstruct the provenance of Cambrian-Middle Ordovician sandstones in the Tayma region, northwestern Saudi Arabia, along with the tectonic setting, paleo-weathering, and paleoclimatic conditions of the source area. This is achieved by the integration of both petrographic and geochemical data (major, trace, and rare-earth elements) of the studied sandstones. The sandstones are collected from the stratigraphic successions comprising the Saq Formation (the Risha and Sajir members, in particular) and the middle member of the Qassim Formation (the Kahfah member). Petrographic analysis reveals that the sandstones consist predominantly of quartz arenite, with subordinate sub-arkose arenite and micaceous quartz wacke. The integration of both petrographic and geochemical data indicates that detritus of the studied sandstones was primarily sourced from Neoproterozoic felsic igneous rocks (mainly granites) with a minor contribution from metamorphic source (mainly gneiss). These source rocks were developed in the interior of a craton, situated within a broad passive continental margin, and were intensely weathered due to prevailing warm and humid conditions. Deposition occurred in intra-cratonic basins after the Arabian-Nubian Shield (craton) stabilized following the Neoproterozoic Pan-African Orogeny, which culminated in the assembly of Gondwana. In terms of a regional perspective, findings of this study support earlier research suggesting that, during the Cambro-Ordovician period, North Africa and Arabia formed a broad, tectonically stable continental shelf along the northern margin of the Gondwana supercontinent, adjacent to the Proto-Tethys Ocean.</div></div>","PeriodicalId":14874,"journal":{"name":"Journal of African Earth Sciences","volume":"233 ","pages":"Article 105849"},"PeriodicalIF":2.2,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145100049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several different AE variants can be used for geochemical anomaly detection, that each can potentially lead to the recognition of different anomalous patterns, complicating the selection of a singular best variant. In the present work, we implement and evaluate four AE variants, i.e., AE, sparse AE (SAE), variational AE (VAE), and convolutional AE (CAE), to compare their effectiveness in detecting geochemical anomalies in the Feizabad region, NE Iran. Our analysis, based on prediction-area (P-A) plots, indicates that the AE outperforms the others with a normalized density index score of 2.85, while SAE, VAE, and CAE scored 2.57. Interestingly, although VAE scored lower than AE, it provided more accurate and meaningful spatial zoning than its peers, even surpassing CAE, which is specifically designed to capture spatial patterns.

In this context, the present study aims to assess the hydrogeological potential of the Gaafour and El Aroussa plains and to define the subsurface structure of the deep untapped Eocene aquifer. The use of advanced gravity filters and the seismic data analysis enabled the identification of buried sub-basins separated by a NW-SE horst, named as the “Oued Mihoub high”, which separates the plain of Gaafour from that of El Aroussa. These two basins are bounded by significant NE-SW and NW-SE fault systems, which control the sedimentary infill and the aquifer geometry. The gravity modeling techniques revealed the configuration and the extent of the various basins and horst structures, highlighting the crucial role of the horst in the hydrogeological dynamics by controlling the direction of groundwater flow, as it diverts it from both sides. In addition, the NE-SW and the NW-SE fault systems play a key role in improving the hydrogeological potential of the aquifer by enhancing porosity and permeability, facilitating infiltration and promoting groundwater recharge.

A total of 25 groundwater samples were collected from Wadi Feiran and Wadi El Sheikh and analyzed for major ions, nutrients, and key physicochemical parameters. The results revealed alarmingly high levels of nitrate (mean = 478.1 ppm) and total dissolved solids (TDS, mean = 2093 ppm), far exceeding World Health Organization (WHO) safety standards, and pointing to substantial potential risks to public health in these arid communities. Although the weighted arithmetic Water Quality Index (WQI) classified all samples as “good” to “excellent,” detailed hydrochemical assessment showed that concentrations of Hofmeister ions—particularly calcium and sodium—surpassed safe average daily intake thresholds in many samples (21 and 16, respectively). Such exceedances raise concerns over the potential development of hypercalcemia, hypertension, and the progression of CKDu, particularly among populations with limited access to alternative drinking water sources. Hydrochemical interpretations suggest that rock–water interactions, evaporation, and anthropogenic inputs are likely contributors to the observed ion levels. Predictive modeling using multiple linear regression (MLR) demonstrated excellent performance (R² = 99.71 % for nitrate), highlighting its value in forecasting contamination trends and identifying groundwater vulnerability hotspots in data-scarce arid regions. These findings underscore the urgent need for targeted groundwater quality monitoring, the integration of predictive risk modeling into management frameworks, and the implementation of preventive public health measures.

Therefore, resistivity, time-domain induced polarization (IP) and spontaneous polarization (SP) methods, field geological and hydrogeological data were conducted to realize this study. Accordingly, the lithological identification, water depth and groundwater zonation were determined. A three-dimensional (3D) resistivity modeling and hydrolithological modeling of sediments were designed to determine their types, extent, water content, water quality and sources. Due to ambiguity in resistivity outputs, the IP method was applied. 3D modeling of chargeability was constructed to differentiate between the deposits and their sedimentlogical and water characteristics, such as separating clay layers from non-clay layers and saltwater. The previous two methods were then supported by building 2D and 3D SP modeling to determine the groundwater flow, specific hydraulic conductivity, infiltration, downwelling and upwelling of water. Thus, the combination of the three methods assisted in understanding, determining and visualizing the deposits properties, downwelling, upwelling and flow of water through them.
