The tide-influenced Pétervására sandstone, early Miocene, Northern Hungary : sedimentology, palaeogeography and basin development

Abstract

The objectives of this thesis are: - to determine the main sedimentary units, the dominant depositional processes, and to reconstruct the depositional environment of the Lower Miocene Petervasara Sandstone (Chapter 3), - to show the pattern of sediment dispersal in connection with the potential effects of small-scale syntectonic processes (Chapter 4), - to document and interpret the tide-inftuenced system (Chapter 5), - to understand its oceanographical background and the reasons for the development of the tidal inftuence (Chapter 7), - to analyze the potential palaeogeographic connections implied by the tide-inftuenced deposits in the basin, with other Early Miocene basins in the Central Paratethys region (Chapter 6), - to pinpoint stratigraphic markers and to establish chronostratigraphic correlations within the formation and also with coeval deposits (Chapter 4 and 8), - to determine the main controlling factors in the development of the depositional environment of the Petervasara Sandstone, and to distinguish signals of tectonics and eustasy (Chapter 8).
