“…Numerous researchers have applied XRD technique for the identification of minerals in sediments and sedimentary rocks (Carrol 1970;Deer et al, 1979;Mitra 1989;Kile and Dennis, 2000;Jimenez-Espinosa and Jimenoz-Millan, 2003;Udayanapillai et al, 2015;Perumal and Udayanapillai, 2020;Ramos-Vázquez et al, 2022;Udayanapillai et al, 2022). Based on high angle XRD mineral analysis (2 theta 0-80 degree), d spacing values and their relative intensities of powdered gryphaea limestone samples reveals the presence of minerals of calcite, siderite, witherite, malachite, smithsonite, azurite and rhodochrosite.…”

Sub-surface Kallankurichi gryphaea limestone formation is observed between Archaean and Quaternary outcrops. Petrographic observation reveals that mega fossils are absent and it contains abundant skeletal fragments of pelecypods, gastropods, foraminifera, bryozoa, and symbiotic algae. X-ray diffraction (XRD) analyses reveal the mineralogical components of both carbonate and clay minerals. Carbonate minerals include calcite, siderite, witherite, malachite, smithsonite, and rhodochrosite. Clay minerals detected are kaolin, montmorillonite, and palygorskite. Major element composition represents predominance of CaO, SiO2, Al2O3, and Fe2O3 oxides, while MgO, MnO, Na2O, K2O, TiO2, and P2O5 oxides are depleted. Statistical analyses of correlation coefficient, principal component analysis, and cluster analysis represent the geochemical affinities and aerial distribution similarities among major elements. Palaeoclimate inferred through biotic proxies, major element geochemistry, and clay minerals represents arid and semi-arid climate.

“…The sorting of mineral grains and the degree of both chemical and physical weathering that sediments have undergone can be evaluated by the chemical composition of clastic sediments (McLennan, 1989;Cox and Lowe, 1996;Roddaz et al, 2006;Ramírez-Montoya et al, 2022;Ramos-Vázquez et al, 2022). To determine the impact of weathering and transport, the chemical index of alteration (CIA) values are calculated and are plotted in the Al2O3-(CaO+ Na2O)-K2O (A-CN-K; Fig.…”

Size, shape, degree of sorting, and composition of sediments in the river channels are controlled by climate, lithology, weathering, sorting, and medium of transportation. The present investigation is focused on the grain-size and geochemical analysis of the channel sediments of the Orsang and Hiren river basins. Major outcrops in the study area are Archaean granites, granitic gneisses, Upper Cretaceous to lower Eocene Deccan Volcanic Basalts (DVB), Quaternary sediments and minor proportion of Proterozoic low grade metamorphic rocks. The sediments are poorly to moderately sorted, very finely skewed, suggesting its derivation from heterogenous sources, while the kurtosis value indicates a high-energy depositional environment. The sediments are with gravelly sand texture and the mean grain size is varying from 581.9µm to 1284.2µm. The DVB provenance of the Hiren river basin and granitic provenance of the Orsang river basin is clearly reflected in the texture and geochemical composition of sediments. The TiO2 and Fe2O3 contents of sediments from the Hiren river basin are distinctly higher and are comparable to the basalts of the Saurashtra region of the Deccan Province. Sediments collected after Orsang and Hiren rivers confluence and from Narmada river show higher concentration of felsic sources, indicating that Orsang river's sediment supply significantly outweighs Hiren rivers. The arkosic-litharenite nature points towards less transportation and moderate chemical weathering for the Orsang river sediments. The low Chemical Index of Alteration (CIA) values (Avg. 48.45 and 56.99 for Orsang and Hiren rivers, respectively) and A-CN-K plot also suggest the supply of sediments from minimally weathered detritus under a semi-arid condition.
