Abstract

A geochemical study of Tse-Kucha limestone of the middle Benue Trough as exposed at Dangote Cement Company was carried out. The study aims at reconstructing the depositional history of the deposit using major and trace elements composition. The chemical compositions of the limestone exposed in the quarry were determined using inductively Coupled Plasma -Emission Spectrometry (ICP-ES) and Inductively Coupled Plasma – Mass Spectrometry (ICPMS) respectively. Petrographic study was also carried out to enhance the determination of biogenic contents of the deposit. Results of fifteen (15) samples collected for analysis put the range of major elements as follow: CaO (43.83-53.32), Al2O3 (0.49-4.02), Fe2O3(t) (0.66-2.13), SiO2 (2.11-10.00), MgO (0.44-1.06), and MnO (0.04- 0.97) respectively. Also the trace elements contents expressed in ppm were found to be Sr (340 – 656), Ba (14-3821), Zr (8-232) Rb (5-49), Ce (5-121), Pb (2-15), Zn (7-72). Interpretation of these results suggest a shallow marine possibly an off- shelf depositional model for the deposit.
