The clinoform architecture from the eastern part of the Drava Basin (Pannonian Basin System) was interpreted to reflect the base-level changes. A major downlap surface interpreted as a flooding event followed by rejuvenation of slope progradation was recognized on 2D seismic sections. Detailed 3D seismic interpretation combined with well data revealed that the large sigmoidal and the overlying small oblique clinoform sets that downlap the large one only apparently produce the geometry of a maximum flooding surface. Instead, the 3D mapping revealed the influence of two competing slope systems arriving from the north and northwest. Lateral switching of sediment input, similar to many recent deltaic systems. e.g., Danube and Po rivers led to the variability of stratigraphic surfaces, lithology, and thickness, which resulted in non-uniform shelf-edge migration. These observations were supported by forward stratigraphic modeling simulating different scenarios, which led to the generation of the depositional architecture with an apparent maximum flooding surface. This study also implies the potential pitfalls in basin analysis based only on scarce 2D seismic and emphasizes the role of lateral variations in sediment input controlling the depositional architecture.

A surface with similar geometric relations, i.e. folded/tilted lacustrine beds overlain by onlaps, can be observed in many places over the Pannonian Basin (PB). The regional nature of this surface led to the conclusion that it can be correlated basin-wide and it is a result of a major lake-level drop related to the Messinian Salinity Crisis (MSC) even though the Lake Pannon had no direct connection to the Mediterranian Sea. In contrast others argue, studying this feature in the eastern part of the PB, that a local interplay of structural events and the superposition of two different sediment feeder systems may have caused the observed geometry. There is still no consensus about the nature or the age of this surface. Prior to the events leading to the formation of this unconformity a significant flooding event took place. Stratal stacking is remarkably different in the Drava Trough compared to the one of the Eastern PB, though large thickness of shallow-water deposits is a common feature. The main goal of this study is to analyze factors controlling stratal geometries and to understand what change of the depositional environments occurred in relation with the above described events. The DionisosFlow stratigraphic modeling software was used constrained by seismic stratigraphy to reveal interactions of controlling factors. The extent of the Pa(n)-4 was traced in 2D seismic sections from the Mecsek Mts. (SW Hungary) to the Papuk Mts. (N Croatia). The model takes into account numerous factors such as sediment supply, tectonic uplift or subsidence rate. With the backstripping method three different scenarios were modeled: a) structural, b) climatic and c) sediment-supply controlled versions. By modifying input parameters, different effects became dominant and the variations in stratal geometries were analyzed. In addition, field observations from the margin of the Papuk Mts. helped to identify similar events in outcrops. A Late Miocene angular unconformity could be studied within the lacustrine succession, between profundal calcareous marls and shallow-water deltaic sands and clays. The hypothesis was tested favoring basin inversion and other factors rather than a major lake-level fall causing the prominent unconformity, with the onlap geometry. Results of the modeling are relevant to the expression of the MSC in the Pannonian Basin. This presentation was supported by MOL Academic Aid Program and NKFIH 116618. LA - English DB - MTMT ER -
