Palynological Zonation of Cretaceous and Early Tertiary Rocks of the Bonnet Plume Formation Northeastern Yukon, Canada
Siltstones, shales, and coals from sections of the Bonnet Plume Formation at the confluence of the Peel and Wind Rivers were analyzed for plant microfossils. Assemblages recovered indicate the presence of 3 pollen-biostratigraphic zones belonging to 3 distinct time intervals. The oldest (zone 1) con...
