Planktonic Foraminifer Biostratigraphy of Norwegian Sea Sediments: ODP Leg 104
Sites 642, 643, and 644 were investigated for planktonic foraminifers. Frequent occurrences of barren intervals caused by dissolution as well as low- diversity and long-ranging assemblages reduce the stratigraphic resolution of these records. Based on Neogloboquadrina species a local zonation, corre...

Sites 642, 643, and 644 were investigated for planktonic foraminifers. Frequent occurrences of barren intervals caused by dissolution as well as low- diversity and long-ranging assemblages reduce the stratigraphic resolution of these records. Based on Neogloboquadrina species a local zonation, correlated with high-latitude North Atlantic schemes, is proposed for the middle Miocene to Quaternary and correlated with paleomagnetic records. The middle to late Miocene boundary is defined by the last appearance datum of Neogloboquadrina mayeri and the first appearance datum of Neogloboquadrina acostaensis.
