Magnetostratigraphic dating of the Badenian-Sarmatian boundary 
The Badenian/Sarmatian boundary in the Central Paratethys corresponds to a major turnover in faunal elements, triggered by strong restriction to the open ocean connections. The aim of this project is to establish a detailed integrated magneto-biostratigraphic correlation between sections in the South Carpathian foredeep of Romania and recently drilled cores from the North Carpathian foredeep in Poland. 
Dating the Badenian-Sarmatian transition in two different domains allows the quantificaton of the potential diachrony between the two regions. Detailed geochemical proxy records may allow the reconstruction of the mode (instantaneous, gradual or stepwise) of salinity increase and to evaluate the contribution of gateway change.
The Badenian evaporites are commonly overlain by a relatively thick series of deep marine to brackish siliciclastic deposits. Very good exposures are found in the Carpathian foreland domain in Romania. In addition, long drill cores through the lower Sarmatian and upper Badenian, reaching the top of the evaporites, were recently obtained in south Poland by our colleagues from Warsaw. We will sample the Badenian-Sarmatian sediments for integrated magneto-bio-stratigraphy (dinoflagelates). The organic rich shales will be studied for high-resolution proxy records (geochemical elements) that may reveal the rates of salinity change and variations in connectivity with the open ocean system.
