Abstract

In the upper Miocene Rodna-Bârgău subvolcanic district (Eastern Carpathians) four calcalkaline rock groups were identified using a classical petrologic approach: Low-K, High-K, Acid and Sial. These groups have different petrochemical characteristics, which, despite the limited area of outcrop, could be related to different magmatic genesis and evolution processes.
