Abstract

Palaeomagnetic direction and K-Ar ages of the youngest volcanics from the Transdanubian Central Mountains are compiled. K-Ar ages indicate that the basalt volcanism took place between 6.0-2.8Ma, and also fix the succession of the individual flows. Magnetic polarity serves as a control in reference to the standard polarity time scale. Although no major mismatch is observed, the results of the 2 different disciplines are not in perfect harmony. The K-Ar ages indicate that the main paroxism took place between 5.0-3.4Ma with minimum 2 distinct phases. During this interval the magnetic field changed the polarity several times and was not biassed either to the normal or the reversed side. On the other hand, the monotonously reversed magnetizations of the rocks belonging to the above mentioned age group seem to point to a single, short-lived violent explosion phase. -from Author
