Geological framework. (a) The Alpine–Carpathian–Pannonian area [3, 14–16, 18]. Abbreviations: ALCAPA: Alpine–West Carpathian–Pannonian block; M: Mecsek Hills; S: Slavonian Mts; V: Villány Hills; HRV: Croatia; HUN: Hungary; ROU: Romania; and SRB: Serbia. (b) Main Alpine tectonic units of the study area according to a previous interpretation [12] and modified boundaries of the Alpine units based on a new concept [17]. Note that the fragments of the Biharia Nappe System have not been proven in Hungary based on the traditional Hungarian tectonic studies and maps [14–16]. Abbreviation: S: Slavonian Mts.
