Schrambach Formation in the Eastern Alps area is conceived from the lithological and stratigraphical point of view rather non-uniform. Therefore a 200 m thick section in the type locality of the Schrambach Formation, situated south of Salzburg, is documented in this study. The studied sequence in the Schrambachgraben seems to be in the prevailing part of section in simple, monoclinal mode of deposition. The opposite is true. The section studied begins with the Oberalm Formation, passes gradually into the Schrambach Formation and ends with the lower part of the Rossfeld Formation. According to our detail results, deposits of the Schrambach Formation in this type of section occur in a minimum of three tectonic slices. The first tectonic slice is composed of a transitional sequence of the Oberalm Formation to the Schrambach Formation. The uppermost part of the Oberalm Formation is dated as the Middle Berriasian Calpionella Zone (Elliptica Subzone).
