In the southern part of the Tokaj-Mountains the kaolin and -bentonite deposits are embedded in rhyolite-tuff-rhyolite of Tortonian-Sarmatian age. These have formed partly due to endogenic and partly exogenic process from orthohypomagmatites, pyroclastics and tuffits. While, in the case of the kaolinization of Végardó — Sárospatak and Mád may also be ranged here — the greater part of the basic rock is tuffit, at Bodrogszegi true pyroclasticum occurs. Here the action of the hydrothermae was the slightest, lasted the shortest time and the exogenic processes exerted their effect to the greatest extent. Usually the formation-sequence of the mineral associations of the different deposits can be traced well. The changes of the pH can be well observed also in the occurrence of some of the characteristic minerals. The formation — sequence of the minerals corresponds to the observed one and it may also be characterised by the decreasing cornpound potentials.
