Palynology and dinocyst biostratigraphy of ODP Leg 104 holes
Cores from ODP Leg 104 Holes 642A, 642B, 642C, 644A, and 644B were sampled at intervals of 40 cm to 100 cm for a detailed study of palynomorphs and palynodebris types in upper Cenozoic sediments of the Vetoing Plateau. Corecatcher samples were also studied from Hole 643A on the seaward flank of the...
