Stratigraphy of coarse grained clastics of the field Obod, Ladislavci and Crnac, Croatia

The stratigraphyc position of the coarse grained breccias is determined as the Upper Oligocene-Miocene (Eggenburgian, Ottnangian, Karpatian and Badennian) after new analyses. Marls or sandy marls and sandstones by progressive gradation or visible sequences are located inside of a laterally to breccia. Very often, there are found kerogen siltites. For instance, it is determined that oil of the Obod field corresponds to the source rocks of the same field.
