  • Glacial and postglacial history of the White Cloud peaks boulder mountains, Idaho, U.S.A.
  • Postglacial timberline fluctuations, La Plate Mountains, Southwestern Colorado
  • Aspects of the postglacial climate of Alberta : calibration of the pollen record
  • Postglacial paleoceanography of Hudson Bay : stratigraphic, microfaunal, and palynological evidence
  • Raised shoreline phenomena and postglacial emergence in south-central Newfoundland in XI congrès de l'INQUA.
  • The change from open to forest vegetation (12,500 yr B.P.) probably represents the most pronounced climatic change in the record and can be interpreted as the glacial postglacial transition in the study area.
  • Paleomagnetic dating of late glacial and postglacial sediments in Lake Superior
  • Postglacial vegetational history of the eastern Avalon peninsula, Newfoundland, and Holocene climatic change along the eastern Canadien seabord in XI congrès de l'INQUA.
  • The AA. provide here the first fossil pollen records from lake sediments from the central treeline zone. They reconstruct the postglacial history of vegetation in the treeline zone and compare their results with previous work from northwestern
  • This paper examines the possibility of a subglacial origin for Bateau Channel (especially the constricted portion midway along its length, here referred to as Bateau Narrows ) and outlines its postglacial evolution as rising levels in early Lake
  • The postglacial history of Lake Manitoba has been deduced from a study of the changes in physical, mineralogical, and chemical variables in sediment cores collected from the lake. Six lithostratigraphic units are recognized in the South Basin
  • A postglacial coleopterous assemblage from Lockport Gulf, New York
  • spectrum, which implies a typically interstadial or postglacial climate in which mixed forest grew in the Toronto area.
  • . These deposits suggest that a significant amount of postglacial isostatic and (or) tectonic deformation has occurred in the Puget lowland since deglaciation.
  • of many hardwood taxa (e.g., ash, oak, elm), and the initiation of bog development are recorded beginning about 13,000 yr B. P. Recent reconstructions of late-glacial and early postglacial vegetational changes provide a context for understanding
