| Popis: |
Sedimentological investigations of the 6500-m-thick Neogene and younger section of the Bekes basin reveal multiple sedimentary processes related to deltaic progradation in a deep lacustrine basin. Cores, well logs and seismic profiles were used to investigate the sedimentologic processes, the paleoenvironments of deposition, and the history of basin filling. A gradual termination of middle Miocene (Badenian-Sarmatian) shallow-marine bioclastic deposition marks the time of accelerated basin subsidence and the onset of lacustrine sedimentation(Pannonian sensu-lato). Three major stages of lacustrine sedimentation are identified. These stages (in ascending order) are represented by: (1) basal calcareous to silty organic-rich marl; (2) prodelta turbidites; and (3) delta-slope deposits. |
