In this research, the assessment of the chemical composition of the Itobe marble deposit for comparison with the general limestone requirements for cement making was investigated. Six pits were dug and carefully studied in the area. The research work is aimed at determining the suitability of the Itobe marble deposit in the manufacturing of cement, establish the nature, size and type of the deposit and to estimate the various impurities present and at what concentrations. The soil samples collected were analysed for their chemical properties. Samples were also obtained from river channels and from outcrops of the deposits. The result showed that an appreciable amount of the marble deposit, with CaO in the range of 32.95% to 50.05% and Silica ranging from 1.40% to 7.20%. From these chemical analyses, Itobe limestone showed a great potential in cement production to augment cement availability for building and civil engineering construction in Nigeria.
