| Description | The locality Nové Syrovice represents the most western outcrop of Neogene marine deposits in SW Moravia. Neogene sands are interpreted as shoreface-foreshore deposits. Sediment supply from the local sources predominates, but material from relative distant sources can be also recognized. Origin of clasts of ferruginous sandstones is connected both with oxidic processes during paleoweathering (in tropic or subtropic climate) and presence of organic material. The exact stratigraphy (Eggenburgian, Lower Badenian?) of the deposits remains unsolved. The paleoecological interpretation brought results about water depth, dynamics, salinity, lighting, aeration and climate. Quartz rich gravels recognised in superposition of Neogene marine sands and in the closest surroundings of the locality represent younger and highly probably fluvial deposits. |
