Titre : « Neogene-Quaternary volcanism of the Carpathian-Pannonian Region, eastern-central Europe: constraints on the magmagenesis from the source to the surface »
The Neogene to Quaternary volcanism of the Carpathian-Pannonian region is part of the extensive volcanic activity in the Mediterranean and surrounding regions. During the last 18 Myr, eruptions of various magmas have been taking place that are closely related to the formation and evolution of the Pannonian Basin. The primary triggering mechanism of these volcanic eruptions was the major thinning of the lithosphere beneath this area. In this talk, a couple of new results will be presented on the syn-extensional silicic volcanism, on the formation and eruptions of alkaline mafic magmas in a post-extensional setting and finally, I address a question how a seemingly inactive volcano can be reactivated and whether new volcanic eruptions can be expected in this region.
