However, its Early Badenian age is known only on biostratigraphical grounds so far. A number of radiometric dating techniques including K-Ar, Ar-Ar and fission-track have been used in order to constrain more precisely its age, allowing the calibration of the Transylvanian Basin's evolutionary models. Although individual dating methods could not provide a unique, reliable and accurate radiometric age, comparison and evaluation of multiple methods gives 14.8-15.1 Ma as the most likely formation age of the Dej Tuff. %K Badenian %K Transylvanian Basin %K radiometric dating %K tephrochronology %K explosive volcanism %K rhyolite tuff %U http://versita.metapress.com/content/n7525750886264g8/?p=6c93371f887c4b44ac59705eaedbff18&pi=3
