    CHARACTERIZATION OF SOME TYPICAL NIGERIAN PORTLAND CEMENTS
    (Department of Geology and Mining, Nasarawa State University, Keffi, 2007-11-23) Jatau, B.S.; Aye, A.E.; Onoja, G.
    This paper presents the results of chemical analyses of Ashaka Portland cement, Burham Portland Cement and Sokoto Portland Cement The results are evaluated with a view of classifying them according to American Standard Testing and Materials (ASTM C150-86) specification and therefore deduce their appropriate uses thereof. The results of the analysis shows that Ashaka Portland Cement constitutes 60.24% CaO, 1.98% Fefi^ 6.73% Al203, 19.45% SiO2, 2.12% S03f 0.78% MgO and 4.6% carbonate carbon. Burham Cement contains 62. 97% CaO, 2.14% Fe203/ 7.28% Al203, 19.07% SO& 1.89% S03 and 1.84% carbonate carbon and Sokoto Portland Cement comprises of 60.18% CaO, 2.69% Fe-fi^ 5.97% Al203, 20.07 SiO% 1.13% MgO, 2.45% S03 and 5.40% carbonate carbon. According to (ASTM C150-86) specification, the result of the analysis shows that Ashaka Portland cement is type I cement which is required for general concrete constructions, Burham Portland cement is type III which usage are suitable for general concrete constructions that require high early strength and Sokoto Portland cement being type IV which is suitable for structural works that require low heat of hydration.

    Evaluation of the processing method of Keana salt deposit, Nasarawa State, North Central Nigeria
    (Department of Geology and Mining, Nasarawa State University Keffi, 2012-10-19) Jatau, B.S.; Aye, A.E.; Abubakar, S.
    The evaluation of the processing method of Keana salt deposit was done by analyzing the salt deposit and the refined salt which was compared with the laboratory refined product obtained by dissolution, filtration, recrvstallization and oven drying processes. In the laboratory process, filter paper was used for the filtration and the residue washed with distilled water before recrystallization. The major elements, sodium (Na) and Chloride (Cl) were determined by flame emission spectrophotometry and mohr's method of titration respectively. Trace elements in the various samples were determined by X-ray fluorescence spectroscopy. The result revealed 32.05%, 3.42% and 33.00% Na in the local processed salt, the deposit and the laboratory refried sT( respectively. The chloride content was determined to be 58.70%, 1.42% and 61.40% Cl " the local refined salt, the deposit and the laboratory refined salt respectively. These 3. e 93 75%. 4.84% and 94.40% NaCI in the local refined salt, the deposit and the Inbora-cfy iefined salt respectively. X-ray fluorescence showed that the following elements are .'resent in the salt deposit. Fe. Zn. Rb, Sr, Zr and Nb. The end-product contained K, Ca, Ti, Cr, Pe. Ni, Cu, Zn, Rb. Sr and Br. The laboratory refined salt contained only Cu, and Cr as trace elements in lower proportion (3.05 x 10'5 and 2.5 x 10'° respectively) compared to their concentrations in the local refined salt (7.93 x 10’5 and 6.54 x 10’6 respectively). Other trace elements associated with the local refined product were totally removed which shows that if modern filtration and evaporation equipment/techniques are used as in industries, it will enhance the quality of the refined product.

    GEOELECTRICAL APPRAISAL OF LOKO GOMA AND ENVIRONS, PART OF JEMAA SHEET 188SW, KOKONA LOCAL GOVERNMENT AREA OF NASARAWA STATE, NIGERIA.
    (Department of Geology and Mining, Nasarawa State University Keffi, 2014-09-11) Jatau, B.S.; Obagu, H.A.; Aye, A.E.
    Geophysical investigation was carried out in Loko Goma and its environs, with the aim of studying the groundwater potential of the study area in Kokona Local Government Area of Nasarawa state, Central Nigeria and lies between latitudes 90 00' 0.00" to 90 02' 45.9" and longitudes 80 06' 17.6" to -80 9' 0.00". The study area covers an area extent of 25km2. The area is underlain by the Basement Complex of the North Central Nigeria. Ten (10) Vertical Electrical Sounding (VES) were carried out in the study area. Interpreted data shows a dominance of A and H type curve. The quantitative and qualitative interpretations revealed some good degree weathered and fracture basement. Iso-resistivity of the true aquifer, depth to basement, basement resistivity and, piezometric maps were delineated. Out of the ten VES, three (VES 1,8 and 10) have been delineated as the most viable locations for good water potentials and moderate at VES7,4,5 and 9, while the least expected yield lies are VES 3,2 and 6. The two types of aquifer, which are weathered basement and fractured basement, have been delineated. This study will serve as useful guide for groundwater exploration in the study area

    GROUNDWATER POTENTIAL OF ANGHIDO AND ENVIRONS, PARTS OF JEMA’A SHEET188 SW, NORTH-CENTRAL NIGERIA.
    (Department of Geology and Mining, Nasarawa State University Keffi, 2015-10-12) Jatau, B.S.; Egga, A. I; Aye, A.E.
    Nine vertical electrical sounding (VES) points were selected out of cultural interferences in Anghido and Environs part of Jema’a sheet 188 SW, Central Nigeria using the Schlumberger array to ascertain the groundwater potentials of the area. The field data curves were typical of KH, A, Q, H and QH types. These were subjected to quantitative interpretations after curve matching using IXID software. The qualitative interpretations from the quantitative result were undertaken using Golden Surfer 8 Computer software. The result of the quantitative analysis gave five to six geoelectric layers consisting of topsoil being clay/sand 300-1500Qm and 0.14-3.2lm, s; lateritic hard pan 216-1615 Qm and 0.8-5.81m, weathered rcgolith43-51' fractured basement 40-902Qm 8.22-53.46m, partially fractured basement 482-1142 Qm and 5.47-11.69m and fresh basement 1142-2048 Qm and infinite depth as their corresponding resisitivities and thicknesses. The main aquifer formations are the sandylateritic, weathered/fracture basement and partially fractured basement. The qualitative results include geoelectric section, piezometric map, true aquifer resisitivity map, depth to basement map, surface elevation map and Basement resistivities map were produce for Anghido and Environs. The groundwater potential ranges from good, moderate and fair categories. The generally groundwater potential varied from location to location. This work is useful for rural water planning and development at Anghido and Environs.

    Physico-chemical appraisal of Agwada chalcopyrite ore, Nasarawa State
    (DEPARTMENT OF GEOLOGY AND MINING FACULTY OF APPLY AND NATURAL SCIENCES NASARAWA STATE UNIVERSITY, KEFFI, 2014-11-24) Jatau, B.S.; Akindele, U. M.; Aye, A.E.
    The physical, petrological and chemical analysis of chalcopyrite ore from Agwada, Kokona Local Government Area of Nasarawa State, Nigeria, was carried out using petrological microscope and XRF spectrophotometer. The physical analysis revealed the following: hardness 3.5, specific gravity 3.8, metallic lustre, light brown greenish colour with reddish brown streak, has an imperfect cleavage and brittle. The petrological analysis also showed that the associated minerals are Biotite, Plagioclase, Muscovite, Quartz, Orthoclase and Sanidine. The chemical analysis results obtained on average is as follows: 5.55% Al203, 19.49% SiOz, 10.63% CaO, 32.91% Fe203, 0-64% MnO, 4.62% CuO, 1.88% ZnO, 4.57% KjO and 16.82% S03. The petrological and chemical analyses of the sample indicate that the chalcopyrite ore is viable for exploitation.
