Stratigraphy
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the coralligneous and nummulitic limestone (unknown lithostratigraphic unit) of the Early Oligocene age that overlies the uppermost part "Marne a briozoi" of the Marna di Priabona Fm. AGE: Early Oligocene. Age justified on the basis of calcareous nannoplankton. STRATIGRAPHIC POSITION: From an outcrop of approximately 5 m thickness at the base (immediately above underlying Late Eocene marl), within 40 m thick local section. | |||||
