Dating endemic Miocene basins in the southern Pannonian region: magnetostratigraphy of Ugljevik (Bosnia & Herzegovina) and Popovac (Serbia)

During my master program I am involved in two magnetostratigraphic projects. Both are focused on dating (partially) endemic environments of the southern Pannonian region in
the Central Paratethys realm. Independent age constraints are of key importance for direct comparison of basin evolution to regional and global climatic and tectonic events.

The Miocene opening and evolution of basins in the Pannonian region are related to the eastward rollback of a Carpathian slab and affected by the rotation of several microplates. The various semi-isolated environments are very endemic, thus cannot be directly correlated to the global record. Therefore the regional Central Paratethys time scale is used locally.

Ugljevik (Bosnia & Herzegovina)

In the Ugljevik open pit mine (Bosnia & Herzegovina) we sampled a 143 m thick sequence of marine deposits from the Badenian (early Middle Miocene). Ugljevik is a unique section since it contains the complete, continuous Badenian succession including the Pannonian marine transgression at its base and the Badenian/Sarmatian boundary at the top. With a combination of paleomagnetism and biostratigraphy (Dr. Oleg Mandic) we determined the age of the marine flooding (~14.2 Ma) and presented a straightforward relationship with other basins in the region ánd nannoplankton fauna of the Mediterranean.

Popovac (Serbia)

In my current project I focus on endemic lacustrine deposits in the Morava corridor. The region is located at the southeastern edge of the extensional Pannonian Basin and lies in between the Dinarides and South Carpathian mountains. The sediments lay stratigraphically below the marine ones of Ugljevik. Correlation of the paleomagnetic data to the Global Polarity Timescale is challenging, since the only available tie points are mammal fauna data of the MN5 Zone (~16.6-14.2 Ma) and preliminary cyclostratigraphy data. The paleomagnetic data suggest ~8° clockwise rotation since the Middle Miocene, which agrees with the clockwise rotation of the South Carpathians.
