Les sols rouges de l’Inde péninsulaire méridionale. Pédogenèse fersiallitique sur socle cristallin en milieu tropical
by G. Bourgeon

characterization of the "red soils" occurring in Peninsular India and the study of their genesis. The "red soils" which are located to the East of the study area, i.e. in the driest zone, generally show carbonate concretions at medium depth. Under this calcium carbonate level, weathering processes are quite limited. Silicates hydrolysis and soil material desilication finally concern only the top layers. To the West, under a slightly more humid climate, soils profiles are generally deeper, carbonates accumulation is no more effective and the weathering processes are more developed. These soils were considered as fersiallitic according to old taxonomic criteria.
