A detailed palynological examination was made of Tertiary pollen and spore assemblages from six exploratory wells located along the continental margins of the Labrador Sea. From north to south, the study wells are Kangamiut 1, Hekja 0-71, Karlsefni A-13, Herjolf M-92, Roberval K-92 and Cartier D-70. Using local extinction events of zonally diagnostic species to define the tops of intervals, eight provisional pollen and spore zones were established. The zones and their relative ages are as follows: Tsuga igniculus (middle to late Miocene); Fagus granulata (early to middle Miocene); Parviprojectus sp. A (early Oligocene); Araliaceoipollenites megaporifer (latest Eocene/earliest Oligocene); Rhoipites latus (middle to late Eocene); Pistillipollenites mcgregorii (early to middle Eocene); Tricolpites sp. A (middle to late Paleocene); and Paraalnipollenites alterniporus (early to middle Paleocene). The middle and upper Oligocene is apparently absent in the study welIs. When used in conjunction with dinoflagellate ...
