Summary: With the exception of a brief (2 m.y.) Late Miocene-Early Pliocene hiatus, an essentially complete Neogene record was recovered on the Kerguelen Plateau in a calcareous biofacies. The stratigraphic distribution of about 30 taxa of Neogene planktonic foraminifers recovered at Sites 747, 748, and 751 (central and southern Kerguelen Plateau) is recorded. Faunas are characterized by low diversity and high dominance and exhibit a gradual decline in species numbers (reflecting a concomitant increase in biosiliceous forms, particularly diatoms) from about 10 in the Early Miocene to 5-8 in the Middle Miocene, 3-4 in the Late Miocene, to essentially a lone (Neogloboquadrina pachyderma) form in the Pliocene-Pleistocene. A provisional sevenfold biostratigraphic zonation has been formulated that, together with the recovery of a representative Neogene magnetostratigraphic record, may ultimately lead to a correlation with low-latitude magnetobiostratigraphies. The initial appearance of N. pachyderma is associated with magnetic polarity Chron (MPC)4 (7 Ma) and MPC 4A (8 Ma) at Sites 747 and 751, respectively. (Auth.)
