The Nové Syrovice locality is the westernmost outcrop of Neogene marine deposits in SW Moravia. These Neogene sands are interpreted as shoreface-foreshore deposits. The sediments are mostly from local sources, although material from relatively distant ones has also been recognized. The origin of ferruginous sandstone clasts found within this deposit is connected to oxidizing processes during paleoweathering in a tropical or subtropical climate and to the presence of organic material. The exact stratigraphy (Eggenburgian, Lower Badenian?) of the deposits has not been determined, though paleoecological studies have resulted in data concerning the depth, dynamics, and salinity of the water, and indicate that the locality was well lit and aerated during deposition. Quartz rich gravels that overlie the Neogene marine sands in the vicinity probably represent younger fluvial deposits.
