    (Indonesian Journal of Chemistry, 2019) Iya, N.I.D.; Assim, Z.B.; Ipor, I.B.; Omorinoye, O.A.; Umaru, I.J.; Jume, B.H.
    This study was to investigate survival, growth and accumulation potential of Acalypha wilkesiana in phytoextraction of heavy metals contaminated soil. Acalypha wilkesiana was tested to evaluate its tolerance and phytoextraction capacity in soils contaminated with metals. It was tested under 10 mL of 100 mg/kg of As, Cr, Cd, Co, Cu, Fe, Mn, Ni, Pb, and Zn solution, along 240 days in greenhouse experiment with harvesting period of 60 days interval. Twenty four cuttings from Acalypha wilkesiana were subjected to the same treatment. Plants roots stem and leaves were dry-digested and analyzed using Atomic Absorption Spectrophotometer (AAS). Results show that Fe was the most accumulated metal followed by Cu, Mn, As and Zn with 5002.4, 542.7, 492.2, 396.7 and 308.2 mg/kg, respectively. The concentration of Cr, Ni, and Co was 101.2, 99.09, and 89.63mg/kg respectively. The highest concentration of Pb was 46.44 mg/kg, Cd was not detected by the plant. Bioconcentration Factor (BCF) of metals were above unity in root, stem, and leaf except for Fe which showed a value below the unity, and Pb shows highest BF value of 7.79. The Translocation Factor (TF) of Cr, Co, Fe, Ni, and Pb were higher, while that of As, Cu, Mn, and Zn were below the unity, Co showed the highest value of 15.93. Furthermore, Extraction Coefficient (EC) of Cr, Co, Ni, and Pb were greater than 1, while for remaining metals were lower than unity, the highest EC was observed from Pb with a value 17.21.

    Geochemical and Mineralogical Investigation of Iron Mineralization in Ardogu and its Environment, Central Nigeria: Implications for Origin and Resource Potential
    (Journal of the Geological Society of Sri Lanka, 2023) Bamigboye, O.S.; Adepoju, S.A.; Omorinoye, O.A.; Bamidele, T.E.; Adefila, I
    Geochemical and mineralogical studies of iron ores in Ardogu and its environments, in central Nigeria were done to characterize it for iron mineralization and resource potential. Thirty core ironstone samples were selected from ten drilled boreholes for geochemical and mineralogical analyses. Geochemical results of selected samples reveal higher concentrations of Fe2O3 with low contents of SiO2, Al2O3, P2O5, CaO and MnO. The geochemical based ternary plot classified the iron ores as ironstone. A petrographical investigation of 10 selected samples reveals the composition of oolites and pisolites with the presence of few quartz grains within the iron rich mineral grains. Qualitative and quantitative mineralogical study using x-ray diffraction shows mineral assemblages including; iron oxides, silicates and carbonates. Mineralogical compositions and textural characteristics of the ironstones suggest genesis related to syngenetic and diagenetic processes. The paleoenvironment during deposition of the Fe-rich sediments is suggested to be an anoxic, organic rich and reducing condition during early diagenesis but with the development of the oolitic and pisolitic textures, there were prevalent oxidizing and dehydrating conditions. The similarity between the chemical data of the studied ironstones with some published data within Bida Basin shows economically viable market values.

    Geochemistry and Origin of Fe-Mn Oxide Mineralization in Kaoje-Derena and Their Environs, Northwestern Nigeria
    (Arabian Journal of Geosciences, 2018) Bamigboye, O.S.; Adekeye, J.I.D.; Kadioglu, Y.K.; Adedoyin, A.D.; Omorinoye, O.A.
    The mineralogy and origin of the schist hosted manganite and sandstone hosted goethite mineralizations west of Zuru schist belt Nigeria was investigated. A total of five goethite and ten manganite samples were selected. Half of each samples were pulverized and subjected to geochemical analysis for the major oxides, trace and rare earth elemental compositions using X-ray fluorescence while the other halves were polished for their mineralogical analyses through Raman spectroscopy. The result of the Raman spectroscopy showed that the manganites were made up essentially of psilomelane, todorokite and brookite, while the goethites were dominantly goethite, rutile and ilmenite. The result of the elemental analysis was subjected to Principal Component Analysis (PCA) using SPSS 22 software and discriminating plots using TriPlot software. The results of the discriminating plots showed that the goethites were related to hydrothermal processes whereas the manganite ores related to detrital-diagenetic processes. The conclusion drawn from the integration of field evidences, geochemical results, mineralogy, cluster analysis and discriminating plots was that the manganite ores were products of supergene enrichment, while in contrast, the goethites were formed primarily from hydrothermal processes but have been remobilized to its present position as a result of changing Eh-pH conditions in Kaoje and its environs.

    Hydrogeochemical profiling and suitability evaluation of groundwater for industrial and municipal applications in the Southern Anambra Basin, Nigeria
    (University of Technology Sarawak, Malaysia., 2026) Iheme, K.O.,; Akakuru, O.C.,; Abubakar, H.O.,; Usman, A.O.,; Alebiosu, M.T.,; Obaro, R.I.,; Olelewe, M.C.,; Omorinoye, O.A.
    Groundwater’s hydrogeochemical properties play a crucial role in determining its suitability for industrial and municipal applications. This study assessed groundwater in the Southern Anambra Basin, Nigeria, by analyzing its physicochemical characteristics and applying hydrogeochemical and industrial water quality indices. A total of fifty-five (55) groundwater samples were systematically collected from boreholes across the study area. Samples were analyzed for key physicochemical parameters, including pH, EC, TDS, major cations (Ca²⁺, Mg²⁺, Na⁺, K⁺) and anions (HCO₃⁻, Cl⁻, SO₄²⁻, NO₃⁻). Data were interpreted using Piper, Gibbs, and Gaillardet diagrams, along with saturation indices and chloro-alkaline indices, to identify hydrogeochemical facies and dominant processes. Industrial suitability was evaluated using the Langelier Saturation Index (LSI), Aggressive Index (AI), and Puckorius Index (PI). The study aimed to (1) characterize the hydrogeochemical facies of groundwater in the Southern Anambra Basin; (2) determine the dominant geochemical processes influencing groundwater chemistry; and (3) assess the suitability of groundwater for industrial and municipal systems based on its scaling and corrosive tendencies. The results reveal that groundwater is mainly of the Ca²⁺+Mg²⁺–HCO₃⁻ and Ca²⁺+Mg²⁺–SO₄²⁻–Cl⁻ facies, dominated by rock–water interactions. Saturation index values for minerals such as calcite, dolomite, and gypsum were <0, indicating undersaturation and a tendency toward dissolution. LSI, AI, and PI values ranged from −3.22 to −0.03, 8.61 to 11.89, and 3.84 to 8.31, respectively implying a high corrosivity and low scaling potential of groundwater within the study area. These findings suggest that the water poses a corrosion risk to metallic industrial and municipal infrastructure. Mitigation measures such as corrosion-resistant materials and pH adjustment are recommended to preserve system integrity.

    PETROGRAPHY, GEOCHEMISTRY AND PETROGENESIS OF GREY GNEISSES OF PART OF OKE-ODE AREA, SOUTH-WESTERN NIGERIA
    (Published by Faculty of Physical Sciences, Chukwuemeka Odumegwu Ojukwu University, Anambra State, Nigeria., 2022) Adedoyin, A.D.; Alebiosu, M.T.; Bamigboye, O.S.; Olobaniyi, S.B.; Omorinoye, O.A.; Iheme, K.O.
    Oke-Ode area, northeast of Ilorin, is part of the Precambrian Basement Complex of southwestern Nigeria. There are no published data on the gneisses, which are well exposed, unlike the adjacent terrains. The area was mapped in order to determine the petrographic, geochemical and petrogenetic attributes of the grey gneisses. The acquired sets of field, mineralogical, and geochemical data indicated that the medium-to coarse-grained gneisses are of igneous origin, and have witnessed multiple tectono-thermal readjustments. Occurrence of xenoliths in the rocks points to magmatic origin. The range of anorthite molecular contents of the plagioclase (An26-34) suggests an andesine to oligoclase composition, indicating derivation from granodioritic to tonalitic progenitors. Petrographic studies showed that the rocks witnessed complex interplay between metamorphism, deformation, and migmatization, which culminated in grain-boundary migration under a relatively stable, low-strain, high temperature conditions involving mechanical rotation, during grain-scale dynamic recrystallization. Geochemically, plots of Ni vs Zr/TiO₂ and K₂O/Al₂O₃ vs Na₂O₃/Al₂O₃ also constrained the the gneisses to the igneous field while the TiO2 - K2O - P₂O₅ ternary plot further indicated a continental tectonic setting prior to the widespread Pan African magmatism. The rocks are essentially peraluminous calc-alkaline rocks, which are moderately saturated with respect to silica. They are products of fractional crystallization of a basaltic magma in a continental setting but later reworked during the Pan African time. The grey gneises have similar geo-chemical characteristics with some gneisses from other parts of the Basement Complex of Nigeria, but at distinct variance with others.

    Shear Sense Analyses of Basement Complex Rocks in Parts of SW Nigeria
    (International Journal of Earth Sciences Knowledge and Applications, 2022) Bamigboye, O.S.; Bamidele, T.E.; Adedoyin, A.D.; Issa, T.A.; Omorinoye, O.A.
    The study area, Oko/Olla is part of Osi sheet 224 southwest and falls within the Basement Complex of South-Western Nigeria. Field and petrological studies revealed that the area is underlain by metamorphic complexes and late intrusives which include: migmatite, granite gneiss, porphyroblastic gneiss, banded gneiss, fine grain granite, diorite with aplite and pegmatite occurring as intrusions. Migmatite is the dominant rock within the study area. The petrogenetic affiliation of the rocks as indicated by the rocks and mineral assemblage represented by plagioclase +alkali feldspar +biotite ±muscovite ±hornblende in the quartzo-feldpartic rocks of the area, are suggestive of amphibolites facies of metamorphism. Kinematic markers which include folds, boudins, σ– and δ–type porphyroclasts, and strike-slip and dip-slip faults were used as shear sense indicators. Detailed analysis of folds revealed asymmetric fold shapes with preponderance of Z– shape folds. The dominant Z–shape drag folds are consistent with the ductile and brittle dextral shear sense indicated by asymmetric boudins and porphyroclasts geometry. Structural analysis from this study indicates that the ductile fabric was overprinted by brittle deformations resulting from the uplift of the area to a low temperature-pressure conditions which is more favorable for brittle deformations. This over printing relationship is suggestive of continued movement of Olla and Oko areas after uplift of the areas during Pan African thermo-tectogenesis. It is therefore concluded on the basis of petrological evidences as well as clear overprinting relationships as revealed by decisive kinematic markers that although there are some sinistral and conflicting shear sense indicators in the area, dominant network of dextral ductile and brittle shear sense in the study area is consistent with the N-S regional structure in the Basement Complex of Nigeria.

    Vertical Profile of Heavy Metal Concentration in Sediments from Sadong River, Sarawak, Malaysia
    (Indian Journal of Environmental Protection, 2019) Omorinoye, O.A.; Assim, Z.B.; Jusoh, I.B.; Durumin-Iya, N.I; Asare, E.A.
    Several sources of heavy metals in the environment include biological, geochemical, geological and anthropogenic sources. A total of eighteen core sediments were taken form Sadong river, Sarawak, Malaysia. These samples were digested by acid extraction and thereafter subjected to Atomic Absorption Spectrometry (AAS). This paper aims to determine the vertical profile of heavy metals in core sediments, infer the accumulation history and assess the possible sources of pollution. The result showed that Fe was the most abundant element wile Cd had the lowest concentration. Sediment pollution assessment was carried out for the top layer using geoaccumulation index (Igeo), enrichment factor and contamination factor. EF values showed moderate to significant enrichment of heavy metals.
