Summary: The biostratigraphic distribution and abundance of Lower Oligocene to Pleistocene diatoms is documented from Holes 747A, 747B, 748B, 749B, and 751A drilled during ODP Leg 120 on the Kerguelen Plateau. The occurrence of Middle and Upper Eocene diatoms is also documented, but these are rare and occur in discrete intervals. The recovery of several Oligocene to Pleistocene sections with minimal coring gaps, relatively good magnetostratigraphic signatures, and mixed assemblages of both calcareous and siliceous microfossils makes the above four Leg 120 sites important biostratigraphic reference sections for the southern ocean and antarctic continent. A high-resolution diatom zonation divides the last 36 m.y. into 45 zones and subzones. This zonation is built upon an existing biostratigraphic framework developed over the past 20 yr of southern ocean/antarctic deep-sea coring and drilling. High-resolution diatom stratigraphy, combined with good to moderately good magnetostratigraphic control, led to the recognition of more than 10 intervals where hiatuses dissect the Oligocene-Pleistocene section on the Kerguelen Plateau. The authors propose 12 new diatom taxa and 6 new combinations in this paper; an additional 41 unknown or poorly documented diatoms are treated with informal nomenclature. (Auth. mod.)
