Distribution of palynomorphs in Miocene sediments of ODP Site 188-1165 in the Prydz Bay, East Antarctica (Table 1) ...
ODP Site 1165 recovered around 1000 m of Early to Late Miocene mixed hemi-pelagic sediments from the Wild Drift, offshore Prydz Bay. Samples from between the bottom of the hole and 110 m below sea floor yielded distinctive palynomorph assemblages, ranging in age from 22.2 Ma at the base to 8 Ma at 1...
