Twenty (20) marble samples from Ubo River area were obtained and subjected to geochemical analysis with the aim of determining the paleo-depositional environment of the original sediments using major elemental composition. The samples were pulverized into powder-form and further subjected to geochemical analysis using Atomic Absorption Spectroscopy (AAS) and Flame Photometer. The results obtained show that CaO ranges between 52.98-82.18%, Al2O3 ranges between 0.01-0.34%, MgO ranges between 1.64-5.32%, Na2O ranges between 0.05-0.43%, SiO2 ranges between 0.01-0.08%, MnO ranges between 0.01-0.03%, FeO ranges between 0.05-1.9% and K2O ranges between 0.02-0.84%. Multivariate statistical analysis was also used to determine the relationship between the variables with CaO vs MgO having fairly high positive correlation indicating fairly high precipitation and Fe2O3 vs CaO having negative correlation indicating low precipitation, respectively. Findings reveal that the carbonate sediments were probably deposited in a quiet shallow marine environment and are very useful in the industrial sector.
