The Sarmatian formations in the Tiszántúl area (East Hungary) and their stratigraphie position
In the hydrocarbon prospecting area of Tiszántúl Upper Miocene formations have been hit by more than houndred bores. The sediments of the Sarmatian stage correspond to the time interval between the Badenian and Pannonian ages. The stage is biostratigraphically bipartite (Kozardian and Tinnyean subst...

| 520 | 3 | |a In the hydrocarbon prospecting area of Tiszántúl Upper Miocene formations have been hit by more than houndred bores. The sediments of the Sarmatian stage correspond to the time interval between the Badenian and Pannonian ages. The stage is biostratigraphically bipartite (Kozardian and Tinnyean substages). In the Tiszántúl area the Sarmatian formations are overlying the Badenian rocks, transgressively near the shore and comformably in the inferior of the basin. They are overlain, on their turn, by different lithostratigraphic members of Pannonian stage. There is a stratigraphic gap of varying importance and at some places a slight angular unconformity to be observed between the Sarmatian and Pannonian stages. The transgressive basal beds of the Kozardian substage are usually overlain by littoral Miliolina limestone. The brackish water Kozardian sediments pass gradually, without any trace of interrupted sedimentation, into the mostly carbonatic sequence of the Tinnyean substage. The formations of this younger substage, however, are missing in the major part of the area, due to erosion, or they are known in some isolated occurrences only. The sediments of the Sarmatian stage are characterized by a brackish water microfauna consisting of a few taxons represented by numerous specimens. Towards the end of Kozardian substage about the half of the forams have become extinct. The Upper Miocene sediments explored in the Tiszántúl area have been deposited in a shallowwater basin of rather complicated shore-line. In the northern part of the area and in the Nyirség at the same time the continental sequence of rhyolitic volcanic formations came into being. The Sarmatian sediments disclosed by hydrocarbon drilling can be correlated biostratigraphically with the sediments of the surrounding basin areas, while the lithostratigraphic units can be traced for short distances only even within the Tiszántúl area. | |
