Calculation of unconformity related eroded stratal thicknesses along the Mid-Hungarian mobile belt in the Danube-Tisza interfluve area, Hungary

led seismic surveys and deep drilling indicate that potential hydrocarbon-bearing formations can be assigned to three tectono-stratigraphic megasequences [8]. The Upper Miocene-Quaternary mega-sequence, of 4–6 km maximum thickness, is represented by molasse formations deposited during the early Late Miocene. The Paleogene-Middle Miocene mega-sequence, consists of 3–4 km maximum thickness infill wrench basins, rifts, half grabens and flexural basins. The Mesozoic mega-sequence includes a rather heterogeneous group of tectonic units. The Mid-Hungarian Mobile Belt (MHMB) is situated above the Szolnok-Sava belt and above it shares boundaries with the ALCAPA and Tisza mega-unites [10]. It is the most significant neotectonic zone of the Pannonian Basin [9]. The faults of the Mid-Hungarian Mobile Belt were active through the complete Neogene period. MHMB recorded multiple deformations during Miocene- Quaternary, witnessing an inherited weakness zone [3, 5, 11].
