Devonian spores, including I1 new species and 2 new varieties, are described and illustrated from the Kenogami River, Stooping River, Sextant, ICwataboahegan, Moose River, Murray Island, and Williams Island Formations in three wells from the Moose River Basin of
the Hudson Bay region. The upper member of the Kenogami River Formation, long regarded as Upper Silurian, is herein assigned to the Gedinnian and Siegenian stages of the Lower Devonian in the Jaab Lake No. 1 and Puskwuche Point No. 1 wells. The Silurian-Devonian boundary probably lies within the
middle member of the Kenogami River Formation. The nonmarine Sextant Formation in the Kiasko River well is correlative with marine strata high in the Stooping River Formation in the Jaab Lake well. The Lower to Middle Devonian boundary lies about one third the way up the Kwataboahegan Formation in
the Jaab Lake well. Stratigraphic range charts prepared for 66 taxa of spores show that close comparisons exist in the spores and in their stratigraphic ranges between the Moose River Basin, the Welsh Borderland and South Wales, the Eifel region of Germany, and eastern Gaspt. Data from these wells
provide a palynostratigraphic reference section for the Lower and Middle Devonian rocks of the Hudson Bay region.
One large bog and five buried bog deposits were sampled in the Ottawa area. Radiocarbon dales, obtained near the base of four of these sections, ranged from about 7, 650 years B. P. to roughly 8 , 830 years B. P. Pollen analysis of samples from the six sites
revealed four zones, Terasmae's zone IV being the oldest. At only two of the sites were all four zones present; at the others, all or part of some zone was missing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
