• Resumen

  • Cretaceous sediments of the Fish Creek test well no. 1 in the North Slope of Alaska were studied for plant microfossils. A total of one hundred-nineteen species of pollen and spores, dinoflagellantes and acritarchs were encountered. The stratigraphic distribution of seventy-one species is summarized in two range charts. Four stratigraphic intervals, based on the recovered species, were established. The geologic age of the Fish Creek sediments was assigned to the Aptian-Maastrichtian stages of the Cretaceous Period. Based on the presence of marine dinoflagellantes and terrestrially derived palynomorphs, the depositional environment is considered to have been predominantly marginal marine.
