Late Cretaceous Dinoflagellate Cysts from the Southern Kerguelen Plateau, Site 738

Abstract

Forty-one samples from the lower section (between approximately 370 and 495.5 mbsf) drilled at ODP Site 738 (southern Kerguelen Plateau) were analyzed for their palynomorph content. The majority proved to be palynologically barren. Twenty-one species and subspecies of dinoflagellate cysts were recorded, however, from the eight samples that proved productive. The irregular distribution of the cysts makes accurate age determinations difficult, particularly for the lower part of the succession. However, species recovered from Cores 119-738C-21R to 119-738C-23R indicate a lat-est Maastrichtian age.
