Description :
Laterites and lateritic soils around Madras have been formed in different geomorphic conditions and on various geological deposits. They occur as caprocks. Detailed analysis (micromorphological and chemical) and the bore hole litho-log data reveal the lateritisation was not continuous but occurred in phases. Geoarcheological investigations and Quaternary stratigraphical studies date the lateritic crust surface to the early late Neogene. Neotectonics have played a vital role in shaping the present landscape.
