Toe-of-slope megabreccia deposits of an Upper Cretaceous rudist platform were studied in the Bakony Mountains. During the Turonian-early Senonian tectogenesis an articulated basin came into being in the area of the Bakony; depressions and highs were formed roughly parallel with the structural strike of the mountains. Inundation of the highs led to the evolution of carbonate platforms. The investigated platform shows an asymmetric architecture. In contrast to its gentle northern slope a steep erosional slope bounded the platform to the south with large, low-angle aprons, the site of deposition of megabreccias. The breccia accumulation occurred within a single 3rd-order cycle commencing in the early highstand and reaching its climax in the late highstand.
