Abstract

Upper Cretaceous rudist platform and slope deposits 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 mountain. Inundation of the highs led to the evolution of carbonate platforms. The studied platform was located in the inner part of the basin separating a southern and a northern sub-basin. Facies studies revealed that the architecture and evolution of the southern and the northern slope of the asymmetrical platform were fundamentally different. A steep erosional slope bounded the platform to the south with lithoclast accumulation at the toe of the slope, whereas a gentle accretional slope was developed northward. Evolution of the platform and the slopes was controlled mainly by two 3(rd)-order relative sea level changes on which higher order oscillation of the sea level was superimposed.
