Palynostratigraphic investigation of upper maastrichtlan and paleocene strata near Tate Lake, N.W.T.
Sedimentary strata near Tate Lake, south of Norman Wells, N.W.T., were investigated using palynomorph analysis indicating the presence of Upper Maastrichtian and Paleocene beds. The Upper Maastrichtian sections contain tv/o local palynostratigraphic zones correlative with Srivastava's Wodehouse...
