Palynological analyses of samples from the Comox Sub-basin, Suquash Sub-basin, and Cretaceous strata of northern Vancouver Island, British Columbia / J.M. Galloway, S.M.S. McLachlan, A. Sproule, S.E. Dashtgard,... : M183-2/9071E-PDF

"This work develops a more comprehensive palynological framework than currently exists for the purpose of improved stratigraphic correlation of Upper Cretaceous strata of northern Vancouver Island. Improved chronostratigraphic control will aid in informing the timing of accretion of exotic terranes to the western Canadian margin as well as to provide new insight into the unique paleovegetation, paleoecology, and depositional environments of northern Vancouver Island during the Late Cretaceous. Pollen, spore, and dinoflagellate cyst-based biostratigraphic analyses are presented on twenty-three samples of Cretaceous age collected from the Comox and Suquash sub-basins of northern Vancouver Island. The samples reveal depauperate dinoflagellate cyst assemblages but diverse and well-preserved pollen and spore assemblages that indicate a Late Cretaceous age for most of the samples. The pollen and spores preserved in the material are representative of the latest Cretaceous Continental Margin floristic province that is characterized by numerous endemic taxa due to geographic isolation from the western interior of North America and a temperate maritime climate"--Foreword, Project summary, page 1.
