The lower miocene deposits of the Raca Subunit near Nowy Sacz (Magura Nappe, Polish Outer Carpathians)

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 Subuni t of the Magura Nappe. These deposits belong to the Zawada Fm., which proba bly overlaps the Malcov Fm. (Upper Eocene-Oligocene) with an erosional hiat us. These folded deposits are represented by medium- to thick-bedded glauco nitic sandstones with intercalations of thick-bedded marls. Facies litholog ical development of the Zawada Fm. displays features characteristic for the northern part of the Magura Basin (Siary facies zone). During the Early Bu rdigalian the partly folded Magura Nappe was flooded from the residual flys ch basin located in the north. At that time the seaway connection between t his basin and the Vienna Basin via the Orava area was probable established.
