The relationship between the geology and the lateritic engineering soils in the northern environs of Akure, Nigeria
Abstract Two contiguously occurring brownish to reddish residual soils in the northern environs of Akure, Nigeria, which show definite relationships in their physical and engineering properties to their parent rocks, have been studied. The parent rocks are coarse porphyritic granite and fine, to medium grained basic charnockite respectively. For each soil, the profile development, clay mineralogy, texture, consistency and the compaction characteristics are investigated. The test results show that the differences in physical and engineering properties are conditioned fundamentally by the parent rock, with drainage and other environmental conditions being practically identical. Although the two soils are both usually described as “lateritic”, the engineering properties of the soils considered on a comparative basis have established the coarse granite derived soil as superior to the charnockite derived soil as road base of fill material generally.
