Forced or normal regression signals in a lacustrine basin? Insights from 3D stratigraphic forward modeling in the SW Pannonian Basin

The overall geometry of sedimentary basins is driven by a complex interplay between subsidence, water-level variations, sedimentation rates and basin-margin topography. Seaward movement the shoreline either high sediment input or base-level drop. influence specific driving mechanisms often overwritten subsequent burial compaction effects it below resolution observational data. Our main aim to describe discuss these internal external forcing factors demonstrate their response, particularly related unconformities clinoform geometries in deep lacustrine setting. To this aim, 3D numerical simulations were performed using DionisosFlow stratigraphic forward modeling software. Models are constrained seismic well data from Drava Basin part SW Pannonian Basin, Central Europe. A wide range parameters, such as subsidence rates, lake-level curves compared analyzed. Post-rift inversion basin have been simulated together with transport routes. calculation infers that paleo-water depth could reached ca. 1300 m deepest parts basin. Furthermore, our models show differential compaction, lateral variations supply result apparently descending shelf-edge trajectories onlapping surfaces misinterpreted drops. By analyzing response different climatic we argue there no direct indication major drop which was much larger than resolution, i.e. 40–50 m. Modeling also autoretreat autocyclic more effective at low higher amplitude variations.
