Abstract

The erubáz soil, a shallow soil influenced by volcanic parent rocks is examined with special emphasis on its clay content and clay-mineral-composition. Several rofiles at 7 study areas and with 4 different parent material types are analysed. Bulk soil mineralogical and clay-mineralogical properties are examined by X-ray diffractometry (XRD). According to the mineralogical analysis the presence of the unstable mafic silicates indicates that the composition of the parent rock is still well reflected in the examined soil profiles. This study revealed that the erubáz soil type is not as homogeneous as it was suggested before. These shallow soils are in the early stage of their pedogenic evolution. Prevalence of illite is suggested followed by kaolinite and smectite. These oils cannot be classified as Andosols by WRB classification but most of them are Phaeozems
