Abstract: In the area of Nowy Sacz the Lower Miocene, marine deposits (of the N 5, NN 2–3 biozones) have been discovered in the southern part of the Raca Subunit of the Magura Nappe. These deposits belong to the Zawada Fm., which probably overlaps the Malcov Fm. (Upper Eocene–Oligocene) with an erosional hiatus. These folded deposits are represented by medium- to thick-bedded glauconitic sandstones with intercalations of thick-bedded marls. Facies-lithological development of the Zawada Fm. displays features characteristic for the northern part of the Magura Basin (Siary facies zone). During the Early Burdigalian the partly folded Magura Nappe was flooded from the residual flysch basin located in the north. At that time the seaway connection between this basin and the Vienna Basin via the Orava area was probable established.
