Soils formed on underlying granitic rocks have similar chemical characteristcs of their rocks. In this paper, soil samples (n=196) and rock samples (n=82) were collected around Mt. Hiei and Mt. Hira, and analyzed quantitatively about silicon, calcium, potassium, iron, aluminum, titanium, strontium and rubidium by X-ray Fluorescence Spectrometry. Chemical data were classified into three groups mainly, the Hiei type, the Hira type and the Kurama type by multivariate statistical analysis. Soils of the Hira type are rich in rubidium and potassium, whereas the Kurama type rich in strontium and calcium and the Hiei type was intermediate between the Hira and the Kurama types. Thus, it was revealed that the inorganic chemical features in granitic soils and rocks were different from each district, and it is suggested that it is possible to discriminate the unlocated granitic soils or rocks through anlyzing their diagnostic elements.
