| dc.description.abstract | The limestone facies of the Gongila Formation constitute an important sedimentary unit in the Gongola Basin. At Ashaka Cement quarry, where the limestone is well exposed and being worked for cement manufacturing, logging and sampling of the limestone beds were carried out and samples selected for geochemical analysis. The chemical composition of ten limestone samples provides insight into the industrial quality of the limestone and environmental effects of some of the associated elements in the study area. Chemical analysis of the limestone shows high CaO (43.06%) content but low MgO (0.70 %) indicating that calcite is the principal carbonate mineral. The low MgO suggests lack of dolomitization process. The limestone saturation factor L.S.F, A.R and S.R values indicate a moderate purity limestone that is suitable for the manufacture of Portland cement. Fe2O3 with average of 2.01% indicates low oxidizing conditions and that the pH of the water was not favourable for formation of Iron III oxides. Low alumina (Al2O3 4.36%) probably reflects low energy environment. The concentration of level of some toxic Trace elements and heavy metals were evaluated and their mean values (ppm); Pb (4.92), Ti (0.94), Cu (8.41), Rb (36.03), Ni (6.70), As (5.87), Cd (0.1), Sn (1.23), and Zn (15.9) are considered not too high to cause health hazard in the environment. | |
