Mineralogy of clay fractions and characteristics of Groundnut growing soils developed from granite-gneiss parent material in Srikalahasti division in Chittoor district of Andhra Pradesh were studied. The clay fraction of these soils exhibited the characteristic peaks of smectite, illite and kaolinite. Semi-quantification of clay fractions based on relative areas under corresponding peaks indicated that the pedon 3 and 6 was dominated by kaolinite followed by illite, smectite and Quartz. Pedons 1 and 2 were dominated by smectite followed by kaolinite, illite and Quartz whereas Pedon 5 was dominated by smectite followed illite, kaolinite and Quartz. Pedon 4 dominated by illite followed by kaolinite, smectite and feldspars.
