Abstract:
The occurrence of Quaternary and Oligocene silicoflagellates at two Ocean Drilling Program (ODP) Leg 119 Holes (736A and 744A) on the Kerguelen Plateau in the Southern Ocean was investigated to compare species distributions to Northern Hemisphere floras. This abstract gives the data determined (Tables 1 and 2) for 24 samples and few preliminary remarks. Quaternary assemblages of Hole 736A are noteworthy for the absences of key North Pacific zonal guide species such as Bachmannocena quadrangula, Dictyocha aculeata, Dictyocha subarctios, and Distephanus octangulatus (Bukry and Monechi, 1985). Other species such as Distephanus floridus, Distephanus speculum elongatus, and Mesocena octagona show limited ranges in Hole 736A and may help to subdivide the Quaternary locally.
The late Oligocene assemblages of Hole 744A contain widely distributed species of Distephanus and Naviculopsis, which permit correlation to lower latitude assemblages. They also contain the high-latitude acme of Distephanus raupii which was first noted at Deep Sea Drilling Project (DSDP) Hole 278 (56°3.42'S, 160°04.29'E, water depth 3689 m) by Perch-Nielsen (1975) and Bukry (1975). Study of Hole 744A assemblages suggests that D. raupii developed from pentagonal Dictyocha deflandrei deflandrei. A final note on the Hole 744A assemblages is the brief late Oligocene acme (25%) of Dictyocha sp. aff. D. spinosa in Sample 119-744A-13H-4, 65-67 cm, which provides a direct correlation to the acme (16%) in DSDP Sample 29-278-31R-CC (Perch-Nielsen, 1975) in the Southern Ocean.
Most of the taxonomy used in the tables is documented in earlier publications of the DSDP Initial Reports (see Bukry in Volumes 16, 35, 37, 40, 44, 49, 54, 67, 68, 69, 81, and 95). Also, see Loeblich et al. (1968) and Perch-Nielsen (1985) for extensive taxonomy and illustrations.
