Abstract:
Representative samples were selected for the study from a large number of profiles. Mineralogical, some micromorphological and pedological investigations of typical samples of red clays in Hungary were performed. On the basis of soil and mineral analysis these red clays can be ranked in various groups:

  •  Red clays in Transdanubia: red clays formed on Permian sandstones, bauxitic formations of Transdanubian Hills,
  •  Red clays of Northern Mountains: red clays of Tokaj Foothills, of Aggtelek Karst, of Northern Periphery of the Hungarian Plain.

Concerning micromorphological features, speckled and granostriated b-fabrics of the groundmass, mainly due to swelling and shrinking, were observed in some samples. Clay coatings are mainly interpreted as micromorphological features of illuviation. Red clays investigated are similar to the tropical and sub-tropical ferrallitic soils in respect of their formation and mineral characteristics.
