Abstract

Twenty marble samples were geochemically analysed using the Inductively Coupled Plasma-mass spectrometry (ICP-MS) analytical method. Major oxides resulting from the analyses are used to calculate the Log ratios of SiO2/Al2O3 and Fe2O3/k2O and which are subsequently used to plot on sand class system adopted by schlumberger. An interpretation of the plottings show that most sediments are classified into the sand class group belonging to greywackes, litharenite and arkose and falling within the range of 0.643-0.89 under SiO2/Al2O3 and of -0.5-0.6 under Fe2O3/k2O respectively. The textural maturity of sandstone and clay matrix reflects the environment of deposition. Lithic greywackes are associated with shallow marine basal deposition. The occurrence of low matrix and high carbonate (CaCO3) content admixed with the greywacke, Litharenite/arkose sediments are evidences of a probable deposition of the parent marble in a marine environment.
