Postglacial history and palynology of Sable Island, Nova Scotia
Sable Island holds especial interest in postglacial palynology because it lies about 180 miles east of Halifax, Nova Scotia, near the edge of the continental shelf and is the only emerged part left of an extensive archipelago which existed on the shelf during the last glaciation. A series of buried soil and peat horizons, ranging in age from about 200 to 11,000 radiocarbon years, has been studied palynologically in addition to surface samples and…
Quaternary palynology ‐ its scope, problems and potential uses
During the past fifty years the scope of Quaternary palynology has widened appreciably. Many other kinds of microfossils besides pollen and spores are included in the field of study. The use of modern data processing methods and the scanning electron microscope are recent additions to the “tool box” of palynology. Research on autofluorescence of fossil pollen is one of several new techniques available to a palynologist concerned with redeposition…
A Study of Late-Quaternary Plant-Bearing Beds in North-Central Baffin Island, Canada
Plant-bearing beds, exposed by downcutting of the Isortoq River at the northern end of the Barnes Icecap, have been folded, apparently by east-west moving overriding ice, truncated and overlain by horizontal alluvial sediments. Radiocarbon dates for plant material from the Isortoq River (folded unit), Flitaway Lake, and Lewis Glacier localities are >30,000 to >40,000 yr BP, from the horizontal beds, 14,000 ± 400 yr BP. The vegetation was probably…
Pollen Diagrams in the Mackenzie Delta Area, N.W.T
Considers postglacial climatic changes in northern Mackenzie District, from palynological and other evidence. Peat from exposures in two areas, also alluvial sediments from a drill hole were analyzed; pollen diagrams with radiocarbon control are presented for the peat. From these investigations and geomorphic interpretation of the exposures, fossil evidence, etc., a tentative climatic sequence is proposed; deglaciation about 12,000 yrs ago, a coo…
Sipre Ice-Corer for Obtaining Samples from Permanently Frozen Bogs
Discusses the effectiveness of sampling devices demonstrated by summer 1962 field use in northern Yukon and laboratory tests in Mar. 1963. Hand drilling in Yukon Territory produced excellent cores, but the cutting teeth in the ice-corer were quickly dulled from mineral matter; holes 7-8 ft deep required three hrs drilling. Tests with power drives indicated that a two-man team could core a frozen bog 8 ft deep in 30-45 min. The two types of power …
