PLANKTONIC FORAMINIFERAL BIOSTRATIGRAPHY OF LATE ALBIAN-CENOMANIAN PELAGIC SEQUENCES FROM THE UMBRIA-MARCHE BASIN (CENTRAL ITALY) AND THE MAZAGAN PLATEAU (NORTHEAST ATLANTIC OCEAN)
Planktonic foraminifera were studied in the upper Albian to Cenomanian sedimentary sequence of the Monte Petrano and Le Brecce stratigraphic sections located in the Umbria-Marche Basin (central Italy), and of Hole 547A and Site 545 drilled by the Deep Sea Drilling Project (DSDP) on the Mazagan Plate...

Planktonic foraminifera were studied in the upper Albian to Cenomanian sedimentary sequence of the Monte Petrano and Le Brecce stratigraphic sections located in the Umbria-Marche Basin (central Italy), and of Hole 547A and Site 545 drilled by the Deep Sea Drilling Project (DSDP) on the Mazagan Plateau (offshore Morocco, northeast Atlantic Ocean).
