| The definition of laterite or lateritic soils is discussed on a climatic condition of tropical and semitropical regions, and the weathering index is indicated by the chemical composition. The chemical composition of$(Fe_2O_3+Al_2O_3)$ of the weathered granite residual soils in tropical and the temperate regions which shelus laterization usually ranges from 0.2 to 0.5. This study shows that the chemical ratio of the Chonju Ajung site is about 0.2U, and that of the regions along the shore of the western sea of Hongsong and Taechon is about 0.33. The chemical ratio of the non-laterite is less than 0.2, and the Kyougju Pulguksa site confirmed about 0.17, The X-Ray diffraction test shows that the clay mineral of the laterite soils is made of kaolinite, this X -Ray result indicates the same characteristics compared with the wrathered granite residual soils of other sites. |
