The Paleogene and early Neogene stratigraphy of the Beskid Sądecki Range and Lubovnianska Vrchovina (Magura Nappe, Western Outer Carpathians)

Abstract

The lithostratigraphy and biostratigraphy of the Bystrica/Tylicz and Krynica facies zones of the Magura Nappe have been studied in the Beskid Sadecki Range and Lubovnianska Vrchovina (Polish and Slovak parts of the Western Outer Carpathians respectively). The new, Tylicz Zone is established, and the Szczawnica, Zarzecze, Magura and Kremna formations are redefined and described. These formations, spanning over 35 myrs, represent a synorogenic deep-water turbidites depositional system that dominated the southern part of the Magura Basin after the collision of the Alcapa Mega Unit with the Czorsztyn/Oravic ridge. The calcareous nannoplankton zones NP14–NP25 (Middle Eocene to Late Oligocene) and NN1–NN2 (Early Miocene) were recognized.
