Anotation:

The project is focused on the time of distinct perturbations of the Earth’s global systems during the Late Cretaceous and Paleogene. Therefore, its research purpose consists in identification of records of extreme climatic and paleoenvironmental conditions from sedimentary formations of the Western Carpathians, which could correspond to global events of oceanic anoxia, biotic crisis at the K/T boundary, hyperthermal conditions at the end of the Paleocene (55 Ma), climatic deterioration up to onset of more expressive cooling at the Eocene/Oligocene boundary (TEE – 33.7 Ma), synsedimentary volcanic activity and extraterrestrial impact, etc. The research will be realized by multidisciplinary approach and application of high-resolution methods, which provide a highest quality of the data for time control, identification and characterization of the stress condition of paleoenvironments. The research practice implies methods of micropaleontology, stratigraphy, biochronology, sedimentology, isotope geochemistry, clay mineral and heavy study, geochronological dating, etc.
