Abstract Williams, G.L. and Brideaux, W.W., 1975; Palynologic analyses of Upper Mesozoic and Cenozoic rocks of the Grans Banks, Atlantic continental margin. Canada, Geol. Surv., Bull. 236: 1-163 Rocks ranging in age from Late Albian to Pleistocene were penetrated in a series of shallow coreholes drilled in 1965 on the Grand Banks, Atlantic Continental Margin. Palynologic analyses of 104 samples from 8 of these coreholes permit the recognition of diagnostic biostratigraphic divisions. These "divisions" are defined on their spore, pollen, and/or dinoflagellate and acritarch assemblages. Informal taxonomic units are used for many of the pollen and spore species and for some of the dinoflagellate and acritarch species. The geologic history and paleoecology can be deduced, in part, from the palynomorph assemblages. The Late Albian was a time of terrestrial deposilion. The Cenomanian-Turonian marked the onset of marine deposition, which was relatively continuous throughout the Late Cretaceous and Tertiary. A climatic cooling first indicated in the lower Miocene strata extended into the Pleistocene.
