Mean 206Pb/238U ages of ophiolites (blue error bars) and associated granitoids and their volcanic equivalents (red error bars) of the East Vardar ophiolites between Greece and Romania (chronostratigraphy after Cohen et al. 2013). The data is sorted geographically from north to south. 206Pb/238U ages for the South Apuseni ophiolites and the Săvârşin, Cerbia and Căzăneşti granitoids and one rhyolite are from this study. U–Pb ages of the Sithonia, Metamorphosis, Guevgueli and Thessaloniki ophiolites (Greece) are from Zachariadis (2007) and Bonev et al. (2015). U–Pb ages of the Samothraki and Evros ophiolites (Greece) are from Koglin et al. (2007, 2009). U–Pb age of the Demir Kapija ophiolite (FYROM) and Ar–Ar Fsp age of a calc-alkaline rock associated with the Demir Kapija ophiolite are from (Božović et al. 2013). Re–Os ages for the Cerbia and Săvârşin granitoids are from Zimmerman et al. (2008). U–Pb ages of the Fanos granite and the Mikro Dassos rhyolite (Greece) are from Anders et al. (2005), that of the Monopigadon granite (Greece) is from Meinhold et al. (2009). U–Pb age for the Chortiatis diorite (Greece) is from Zachariadis (2007), and that of the Gerakini diorite, interpreted to belong to ophiolites although enclosed within the Chortiatis island-arc suite, is from Bonev et al. (2015). A maximum age of obduction (~153 Ma) of the South Apuseni ophiolitic unit can be inferred from the youngest calc-alkaline intrusive body (sample DG072). Note that the errors reported for literature data are standard-errors-of-the-mean, whereas the errors calculated for the Apuseni ophiolitic rocks and granitoids also include systematic external errors. This leads to seemingly larger errors of samples from this study
