The presence of extraformational clast within the Enugu Shale indicates that there was fluvial influence during the period ofdeposition of Enugu Shale within the Anambra Basin (Tucker, 1996). The light grey colour of the shale shows that Enugu Shale was deposited on the surface of the basin where oxidation could take place (Dapple, 1974).
