Multiproxy reconstruction of Eurasian Megalakes connectivity and isolation patterns during Neogene-Quaternary times
This project aims to investigate the geological formations corresponding to the Parathetys and Euxine mega-lakes (currently the Black Sea), through an interdisciplinary approach that integrates high-resolution biostratigraphy, organic geochemistry and geochemical proxies (strontium isotopes – Sr), combined with geochronology techniques (paleomagnetism and 40Ar/39Ar dating).
Methods
During the project we will carry out multidisciplinary investigations focused on geochronology (magnetostratigraphy, tephrochronology and stratigraphy), biostratigraphy (micro- and nannofossils), organic and inorganic geochemistry (87Sr/86Sr and 187Os/188Os analyses, 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 paleomagnetic laboratory of Utrecht University for magnetostratigraphy studies (free of charge), the laboratory of the Senckenberg Climate Research Institute for organic geochemistry studies.
The project aims to answer the following questions:
- What happens during and after megalake formation, due to the disconnection of marginal seas from the planetary ocean?
- What happens during and after the disappearance of megalakes due to the reconnection with the planetary ocean?
- What is the rate of endemism?
- What were the impacts and implications of the observed paleohydrological changes, beyond the Paratethys-Euxinic region?
