Abstract: Conspicuous differences in both particle size classes, morphological and chemical properties of soils was attributed to the underlying diversified geological materials which were the parent materials of the soils as it was confirmed by the total elemental analysis of soils, molar ratio and CEC/Clay ratio. Intermediately siliceous grey shale and pink shale derived pedon-2 and 3 registered moderately deeper solum depth, finer texture and well developed soil structure as compared to the high siliceous sandstone derived pedon-7. The soil reaction, CEC, total exchangeable basic cations as well as percent base saturation were comparatively low in highly siliceous sandstone derived pedon-7 than in the soils derived from intermediately siliceous grey shale and pink shale. Soil depth of calcareous limestone derived pedon-4 was shallow, while soil texture and structure and CEC were in between shale and sand stone derived pedons. Pedon-4 was calcareous unlike other pedons. Positive correlation of SiO2 with sand (0.015), coarse fragments (0.045) and negative correlation with clay (-0.134) suggested the influence of parent materials on soil properties. Soils under study were keyed out at subgroup level as Vertic Haplustepts (Pedon-2), Typic Haplustepts (Pedon-3), Lithic Usthorthent (Pedon-4) and Lithic Haplustalf (Pedon-7).
