Illite deposit of Fiizerradvany is a part of a low sulphidation type epithermal system hosted by an Upper Miocene (Sarmatian) volcanoclastic and sedimentary sequence. Mineable high quality illite bodies were formed along siliceous veins due to interaction of hydrothermal fluids with permeable rock units. In order to get highly reliable K-Ar data for timing of the hydrothermal activity, careful sample preparation and duplicate analyses on illite samples in two independent laboratories (Institute of Nuclear Research, Hungarian Academy of Sciences and Okayama University of Science, Japan) were carried out. On the basis of the results, the most probable age of mineralization is 11.89 ± 0.3 Ma. This result is in agreement with previous data suggesting that hydrothermal mineralization exposed in the Tokaj Mts. took place during the Middle-Upper Miocene (Sarmatian) paroxims of volcanism.
