A systematic and comprehensive study regarding elemental/trace metal impurities in kaolin and talc is lacking. 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. However, the toxic elemental impurity level was low as compared to Indian and European Union standards for soils. The present study explores the existence of major trace elemental impurities in kaolin-talc clays. Furthermore, the multivariate analyses described that the major sources of existing elemental impurities are attributed as being from different geogenic sources.</p></div>","PeriodicalId":476,"journal":{"name":"Arabian Journal of Geosciences","volume":"18 4","pages":""},"PeriodicalIF":1.827,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143676473","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 analyses were performed using statistical methods. The study found that, on an hourly and daily average, PM₁, PM_2.5, PM₅, and PM₁₀ concentrations, in particular, range 24–127 µg/m³, 44–210 µg/m³, 48–225 µg/m³, and 50–240 µg/m³, respectively. Diffuse concentrations are found at locations with significant concentrations of pollutants, according to spatial mapping (Q3, Carrefour Ndokoti; Q5, Carrefour PK14). PM₁₀ and PM_2.5 particle air quality indices fall into the bad and extremely poor categories. For Q3 and Q5, the PM_2.5 air quality index is 660.86% and 580.46%, respectively. In contrast, Q3 and Q5 PM₁₀ levels are 264.97% and 231.37%, respectively. While Q5’s high concentrations are caused by the phenomenon of re-suspension brought on by the presence of unpaved roads, Q3’s high concentrations are the result of the area’s significant traffic. According to the study, the levels of PM_2.5 and PM₁₀ are five and eleven times higher, respectively, than the most recent WHO limits for daily exposure. This study provides important information on the pollution levels in Douala, which should be considered since they could be a major cause of illness in the area.</p></div>","PeriodicalId":476,"journal":{"name":"Arabian Journal of Geosciences","volume":"18 4","pages":""},"PeriodicalIF":1.827,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655355","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}

Groundwater potential zones (GWPZ) within the Jericho area of Ibadan, Southwestern Nigeria, were investigated using an integrated geophysical (electromagnetic profiling and electrical resistivity) approach. Vertical dipole (VD) and horizontal dipole (HD) surveys for the electromagnetic profiling (EMP) were executed along eleven (11) E-W profile lines 250–400 m long. The electrical resistivity methods included horizontal electrical resistivity profiling (HRP) using a current electrode (AB) spacing of 45 m at a 15 m measurement distance and 2D-multichannel resistivity tomography (MRT) with a minimum 5–7 m dipole length depending on the extent of each traverse line. Sixty-two (62) vertical electrical sounding (VES) were carried out at selected ground points with maximum AB/2 = 100 m. The EMP results reveal conductivity values for VD ranging between − 214 and 336 mS/m (average = 21 mS/m) and HD between − 24 and 56 mS/m (average = 14 mS/m). Furthermore, apparent resistivity values for HRP range between 575 and 14 Ωm (average = 134 Ωm), reflecting a moderately conductive subsurface lithology. The 2D MRT section revealed three to five subsurface layers, with aquifer thickness of 1–30 m. VES results reveal H, AK, HK, HA, QH, and HKH curve types revealing multiple layering systems (3–5 geoelectric subsurface layers) with varying resistivities and thicknesses (topsoil = 14–599 Ωm, 1–2 m; lateritic clay = 13–72 Ωm, 0.44–19 m; quartzitic/pegmatite unit = 288–1070 Ωm, 1–37 m; weathered saprolite = 10–2950 Ωm, 4–18 m; and fractured/fresh basement rock = 472–16,908 Ωm, 1–43 m).

This study focuses on the Middle Paleocene to Early Eocene sedimentary section, using comprehensive whole rock major and trace element geochemical analyses to investigate paleo-oceanic conditions in the Northern Indian Ocean during this critical interval. Examination of redox-sensitive trace elements revealed temporal shifts in paleoclimatic conditions, indicative of warmer climates during the mid-late Paleogene period. Variations in elemental ratios, such as Rb/Sr and Sr/Cu, reflect changes in weathering intensity and terrestrial input, mirroring shifts in precipitation and climatic regimes. Insights from Zr/Rb ratios highlight past hydrodynamic conditions, suggesting deeper water and lower hydro energy environments. Fluctuations in Zr/Rb values, notably in the P/E samples, suggest relatively heightened wave energy during warmer climatic conditions in the tropical northern Indian Ocean. Diverse Paleogene depositional geomorphologies and seismic data point to increased total rare earth element (ΣREE) concentrations at the P/E boundary, attributed to amplified terrestrial input. Shale-normalized REE patterns and positive interelemental relationships further underscore the influence of terrigenous sources on sedimentary REE distributions. Negative Ce anomalies within studied sections suggest oxygenated environments during deposition, with minimal fluctuations in the bottom water oxygen content. Positive correlations between Ce/Ce* ratios and terrigenous materials emphasize the impact of detrital siliciclastic materials on sedimentary redox conditions. Overall, these geochemical findings provide critical evidence for significant shifts in paleoceanic conditions during the Paleocene–Eocene transition. The integration of multiple geochemical proxies elucidates the interplay between climatic fluctuations, hydrodynamic regimes, and terrestrial input, underscoring the Mannar Basin’s role as a valuable archive of past environmental change.</p></div>","PeriodicalId":476,"journal":{"name":"Arabian Journal of Geosciences","volume":"18 4","pages":""},"PeriodicalIF":1.827,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143638154","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}
