The clays vary in thickness from 10 feet to some 38 feet, depending on the lithology of the underlying rock and the topography of the area. Laterite was encountered in a good number of holes and thicknesses up to 8 feet were recorded. Thin horizons of variable plastic clays were encountered suggesting apparently a banded argillaceous parent rock. In some hotes the clay was of low plasticity towards bedrock and it is thought that such zones represent the weathered bedrock ER -
