The evolution of the West and Central Paratethys
during the early-middle Miocene: chronology, paleogeography and tectonics
age data are of key importance for making paleogeographic reconstructions,
because they allow us to compare and connect different regions
other. In my PhD-research I aim to get a better understanding of
paleogeographic changes that occurred in the West and Central Paratethys during the
Miocene. To do so, I am integrating magnetostratigraphic and
radio-isotopic results with data from other disciplines, such as
biostratigraphy, sedimentology, geochemistry and structural geology.
During the Lower-Middle Miocene, the
evolution of the West and Central Paratethys is controlled by a
complex interplay of regional tectonics and global climate changes. At
times, a sea strait to the Mediterranean opened and the
environments became fully marine. At other times, no connection to the
world oceans existed. In these times, many endemic faunal assemblages
are very difficult to correlate to the global time scale. Therefore,
the use of independent dating techniques is very important if we want
to compare the Paratethys environments to the global record.
My study area stretches from South Germany to West Romania and has
localities in the Molasse Basins (North Alpine Foreland Basin), Pannonian
Basin, Dinaride Lake System and Carpathian Foredeeps. On this page I give you an insight into some ongoing fieldwork projects of my PhD.

Paleogeography of the Paratethys region during the Middle Miocene (~13 Ma). Red box: W. & Central Paratethys
(Bosnia & Herzegovina)
Nearby Ugljevik (Bosnia & Herzegovina) we sampled a 143
sequence of marine deposits from the Badenian (early Middle Miocene).
is a unique section, because it contains a complete, continuous Badenian
succession including the Badenian marine
transgression at its base and
the Badenian/Sarmatian boundary at the top.
With a combination of
and biostratigraphy (Dr. Oleg Mandic) we determined the age of the
(~14.2 Ma) and presented a straightforward relationship with paleogeographic changes in the
Paratethys region ánd with bio-events in the Mediterranean.

Sarajevo-Zenica Basin (Bosnia & Herzegovina)
Although the Sarajevo-Zenica
Basin is the largest lacustrine basin of the Dinaride Lake System, no proper age
constraints are available for its >2000 m thick sedimentary infill. The basin evolution is partly controlled by the same
tectonic and climatic mechanisms that control the Central Paratethys
region. We are carrying out an intensive, integrated magnetostratigraphic,
sedimentologic and structural field study in order to create a chronostratigraphy
and understand the interplay in between sedimentation with tectonics.
results suggest an asymmetric extensional basin system in which sedimentation patterns are
linked with normal fault activity. The Lower-Middle Miocene age of the
infill is probably similar to the other Dinaride Lakes in Bosnia and

Apart from the field projects above, my trips already brought me to cement and underground mines in Serbia, drill core
storages in S-Germany and Hungary and (extremely muddy) river sections in Romania.
