Diatom communities at DSDP Holes 95-612 and 95-613

Samples from Sites 612 and 613 along the New Jersey transect were examined for diatoms, utilizing the processing methods of Abbott (1978) as well as heavy liquid concentrations. The diatom biostratigraphy at these two sites was difficult to interpret because of the apparent frequent reworking into a rare, poorly preserved, indigenous flora and the lack of stratigraphic markers. The actual numbers of specimens found per slide for each species are listed in Tables 1 and 2. Reworked species are indicated with an asterisk and are primarily of Miocene and Eocene age.
