heal.abstract	Diffusion rings (sphaeroids) in bauxites from Klisoura (Dunionia), Helicon, Greece, are described and are studied mineralogically by X-ray diffraction and ore-microscopically. These diffusion rings are also analysed by X-ray fluorescence spectroscopy. The diffusion rings have Fe-rich and relatively Fe-depleted zones. Element leaching and mobilization under weathering is proposed to be the mechanism responsible for the formation of these diffusion rings. A comparison with similar diffusion rings in granite also suggests element leaching as the process responsible for their formation. © 1980.	en
