The extraction method of lineaments from remote sensing data required some pre-processing of the Landsat satellite image spectral bands to reduce the effect of the atmosphere and geometric distortions during data acquisition. The automatic lineament extraction was performed with the PCI Geomatica 2016 software for Landsat images and manually for SRTM on ArcGIS. Automatic lineament extraction was applied to the PC1 and PC2 bands of the Landsat-8 OLI image and each of the four shaded relief images of the SRTM images (N0°, N45°, N90°, and N135°). The results reveal 909 lineaments ranging from 21 m to 10.1 km, with an average length of 1.98 km and a standard deviation of 1.27. The lineaments on directional maps and rose diagrams show 8 directions with the predominance NE-SW. The secondary directions are NW–SE and WNW-ESE. The results are validated by the structural data measured in the field, the geological map of Cameroon, the hydrographic network, and the slope map.

In this research, the western part of the Kopet-dagh Orogen, as the southern boundary of the Turan Plate, is selected as a case study for investigation on tectonic development and deformation patterns, using surface–subsurface structural studies together with complementary remote sensing and GIS environmental capability as a multi-disciplinary approach. The results of this research determined two sets of faults, consisting of (a) first-stage longitudinal reverse faults with a structural trend of N90–100 to N50–70 (Tangrah, Takal-Kuh, Marave-Tappe, and Golijeh faults), and (b) transversal right-hand strike-slip faults with a trend of N130–150 (Kalaleh, Ughcheh, and Sarighamish faults). These two sets of faults formed the structural framework of this zone and played an important role in the tectonic evolution (initiation, shaping, evolution of sedimentary basins, and forming a fold-thrust belt) of this orogen. A change in the mechanism of the first-stage longitudinal faults, as tectonic inversion, at the onset of the Late Alpine Orogeny caused the re-arrangement of P-axes and thus formed bi-vergent reverse faulting in the northern and southern edges of this zone. Subsequently, fault propagation folds were established due to this event. Finally, an extensive V-shaped compressional pop-up structure with bi-vergent thrusting and fold axial surfaces (as fault-related folds) was formed in the Kopet-dagh fold-thrust belt. Also, the mechanism of the second-stage transversal faults changed to right-hand strike-slip faults with some normal components at the onset of the Late Alpine Orogeny. The normal component of these faults (especially the Kalaleh fault) caused the settlement of the western part of this zone along them and formed the Gorgan-Gonbad plain.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":476,"journal":{"name":"Arabian Journal of Geosciences","volume":"18 5","pages":""},"PeriodicalIF":1.827,"publicationDate":"2025-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143821779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study utilized monthly data of rainfall, temperature, evaporation, and streamflow for the latest month (Q_t-1) and the preceding 2 months (Q_t-2) in the Hamoon Helmand catchment. Five scenarios were employed in M5 and the linear and nonlinear models of GA and LSTM. The models’ performance was assessed using statistical parameters such as RMSE, MAE, R, and NSE. In the initial scenario where all five parameters were considered, M5, the linear and nonlinear GA models and LSTM produced the most accurate results, with RMSE values of 9.27, 6.87, 5.54, and 5.55, respectively. The second scenario (rainfall; maximum, minimum, and average temperatures; Q_t-1 (discharge for 1 month before) and evaporation) revealed that the linear and nonlinear GA models, with RMSE values of 7.21 and 6.55, respectively, were more accurate than M5 and LSTM with an RMSE value of 8.58 and 6.78, respectively. In Scenarios 3 (rainfall; average temperatures; evaporation; and Q_t-1, Q_t-2 (discharge for 1, 2 months before)) and 4 (rainfall; average temperatures; Q_t-1, Q_t-2 (discharge for 1, 2 months before)), LSTM demonstrated superior performance. The results obtained from Scenario 5 (rainfall; maximum, minimum, and average temperatures and evaporation) indicate that in the absence of sufficient runoff data in a basin, there is no necessity to employ a nonlinear model; instead, modeling with an M5 model tree yields sufficiently accurate results.

Listwaenite is gaining worldwide interest due to their possible economic value as gold bearing rocks and assessing the global carbon sequestration and flux. This work presents new petrographic and geochemical data of listwaenite from Fanja and Islam Abad area and estimates the physical and chemical conditions of their formation. Three types of listwaenite are known to occur within ophiolites worldwide, and these include silica-, carbonate-, and silica-carbonate. Typical minerals which are usually known to occur in these listwaenite include dolomite, ankerite, calcite, magnesite, quartz, iron oxides, relict chromite grains ± talc and serpentine. Calcite- and magnesite-dolomite listwaenite is more abundant in the Fanja area, while dolomite listwaenite is more abundant in Islam Abad area. The major element chemistry of the different types of listwaenite in both Fanja and Islam Abad area is largely similar to that of altered ultramafic rocks and listwaenites from other ophiolites occurrences. In comparison to the primary mantle and chondrite spider diagrams, the Islam Abad listwaenite shows higher trace and REE elements abundance than those from the Fanja area. The variable and high abundances of Ca, Mg, Ba, Zr, Sr, Pb, Zn, Mo, and W in the carbonate- and silica-carbonate listwaenite indicate a hydrothermal source from the sedimentary and metamorphic units of the Arabian Platform underlaying the listwaenite. Depletion and enrichment of major and trace elements in the listwaenite are indicative of large fluctuations in major and trace element mobility, where listwaenite preserves different stages of gradual alteration of their ultramafic protoliths. The listwaenite content of CaO, SiO₂, and MgO depends on the stage of listwaenite formation, in which carbonate listwaenite is formed in the first stage, progressing to silica-carbonate listwaenite in the final stage. The listwaenite in Islam Abad and Fanja area was altered to different stages by hydrothermal alteration of serpentinite and harzburgite along Late Cretaceous thrust and Paleocene-Miocene extensional faults and shear zones, which acted as pathway for trace elements and Ca and/or Si rich fluids at different times probably during subduction and/or post obduction stages.</p></div>","PeriodicalId":476,"journal":{"name":"Arabian Journal of Geosciences","volume":"18 4","pages":""},"PeriodicalIF":1.827,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, blending is done manually by mineral researchers who analyze samples, set blending specifications, and create blends, often compromising the overall quality. This study proposes the use of an artificial neural network (ANN) model, specifically the radial basis function neural network (RBFNN), to classify blend quality in Egypt’s Aswan region. The model, powered by the radial basis function (RBF), efficiently handles large datasets and reduces the costs of achieving optimal blending. Using expert-judged “best blend” data for analysis and prediction, the RBFNN model demonstrates superior performance in terms of accuracy, precision, recall, and F1 score compared to traditional methods.

Thus, the present study investigated elemental impurities in kaolin and talc and their source apportionment pattern. For this concern, a total of 50 kaolin samples from the Bhuj area of the Kutch basin (Gujarat, India) and 30 talc samples from the Mahi-Banas basin of Rajasthan (Bhilwara, Udaipur, and Dungarpur) were analyzed. The major trace element impurities such as lead (Pb), chromium (Cr), copper (Cu), nickel (Ni), arsenic (As), manganese (Mn), and zinc (Zn) were detected in kaolin-talc clays from inductively coupled plasma optical emission spectrometry (ICP-OES) technique. Further, the source apportionment study was carried out by using multivariate analyses such as principal component analysis (PCA), hierarchical cluster analysis (HCA), and Pearson correlation matrix (PCM). The results indicated that the mean concentrations of trace elements Cr, Pb, Mn, Ni, Zn, Cu, and As in kaolin were 114, 57.82, 33.31, 20.36, 16.51, 10.98, and 0.05 mg/kg, respectively, whereas 2.53, 0.63, 159, 5.05, 20.11, 1.22, and 11.23 mg/kg, correspondingly, in talc samples.
