Book excerpt: Laterite deposits are known to occur extensively on Indian Peninsula having derived from varied geological formations of different ages. These deposits are derived from khondalite and Charnockite groups of rocks in the Eastern Ghats, granite gneisses in Karnataka, Vindhyan sandstones in Utter Pradesh, Deccan Trap basalts in Madhya Pradesh, Gujarat and Maharastara, Gondwana sand stones in Madhya Pradesh, Sirban lime stones in Jammu and clastic sediments in Gujarat. Laterite deposits associating with all these rock types occur as cappings or blankets. Laterites associated with a particular geological formation show compositional variation with altitude. Enrichment of aluminium generally takes place on the broad topped and gently sloped hills, whereas enrichment of iron on slopes of hills and on plain areas, even though the process of lateritisation has taken place on the same type of rock and in the same climatic zone on mega scale. The iron-rich laterites confined to a specific altitudinal range in the study area has led the author to make thorough investigation on these laterite deposits with reference to their mode of occurrence, mineralogy, mineral alteration, geochemical behavior of elements and various other processes that are in operation during lateritisation.
