Multiproxy reconstruction of Eurasian MEGALAKES connectivity and isolation patterns during Neogene-Quaternary times
This project wants to investigate the geological formations corresponding to the mega-lakes Parathetys and Euxin (currently the Black Sea) through an interdisciplinary approach that integrates high-resolution biostratigraphy, organic geochemistry and geo-echemical proxies (strontium isotopes – Sr), combined with geochronology techniques (paleomagnetism and dating 40Ar/39Ar).
Methods
During the project we will conduct multidisciplinary investigations focused on geochronology (magnetostratigraphy, tephrochronology and stratigraphy), biostratigraphy (micro– and nannofossils), organic and inorganic geochemistry (analyses 87Sr/86Sr and 187Os/188Os, stable isotopes), sedimentology, petrography, paleomagnetism and paleogeographic reconstructions. We will combine the research infrastructure of the GeoEcoMar Institute with the European research network. The project team will be able to use the University of Utrecht’s paleomagnetic laboratory for magnetostratigraphy studies (no cost), the Senckenberg Institute of Climate Research laboratory for organic geochemistry studies.
The project aims to answer the following questions:
- What happens during and after megalakes, due to the disconnection of marginal seas from the planetary ocean?
- What happens during and after the disappearance of the megalakes due to the reconnection with the planetary ocean?
- What is the pace of endemism?
- What were the impacts and implications of the observed paleohyrological changes beyond the Paratethys-Euxinic region?
