We present the first apatite and zircon fission-track results coupled with new muscovite and biotite 40Ar/39Ar analysis on samples from the pre-Mesozoic granitic basement and the Upper Cretaceous to Danian volcano-sedimentary cover, which allowed us to reveal the Alpine thermal and tectonic evolution of the central parts of Sredna Gora Zone. Our new results disclosed the existence of several heating and cooling episodes related to distinct tectonic and magmatic events in the studied area.
