ABSTRACT
There has recently been an increase for the usage of clay minerals. Hence, the driving force for this research work which was carried out to determine the sedimentological properties of Okhoro clay deposits in Edo State, Southern Nigeria. In this study, five (5) fresh clay samples were collected from Okhoro and were subjected to particle size analysis to determine their mineralogy, grain size using hydrometer method. The relative proportion of sand, silt, and clay in soils determines soil texture and affects soil characteristics such as nutrient retention and leaching and water holding capacity and drainage. The hydrometer method of particle size analysis calculates the physical proportions of these soil particles based on their settling rates in an aqueous solution.
