Sažetak
The Transylvanian Basin (TB) in Romania accommodates a several-hundred-meter thick upper Miocene (Pannonian) sedimentary sequence. Data on its fossils are sparse and scattered in the literature. Consequently, the biostratigraphic subdivision and chronostratigraphic assessment of this sequence, representing about 2.5 Ma, are relatively poorly developed with much uncertainty (Lubenescu 1981). The mollusc and ostracod biostratigraphy were largely based on the biozonations established for the shallow-water deposits of the Vienna Basin many decades ago (Papp 1953). The magnetostratigraphic correlation of some recent polarity measurements partly remained disputable (Vasiliev et al. 2010, de Leeuw et al. 2013). Radiometric age measurements have never been published from these formations. To improve the stratigraphic resolution and the reliability of correlations in the Pannonian of the TB, we investigated outcrops of mostly deep- water formations across the TB. Beside the thoroughly investigated Sarmatian/Pannonian section in Oarba de Mureş(Sütő & Szegő 2008, Vasiliev et al. 2010, Filipescu et al. 2011), we focused our research on the highly fossiliferous sequence of the Guşteriţa outcrop, representing younger Pannonian sediments.
