An Ecostratigraphic Study Of Late Pleistocene Sediments Of The Western Champlain Sea Basin Ontario And Quebec

Five marine pelecypod and cirriped associations, one greshwater pelecypod association, seven foraminiferal associations, and five groups of ostracode assemblages are recognized in Late Pleistocene sediments of the Thurso, Russell, Winchester, and Morrisburg map areas. Salinity and substrate are the primary factors controlling the distribution of macrofossils and microfossils.

The 13 papers in this collection examine the coastal regions, the Gulf of Maine, and the continental shelf off of Atlantic Canada in context with new radiocarbon age analyses, providing a detailed history of climate changes, marine transgression, emergence, and relative sea- level history. Specific topics include deglaciation of the Gulf of Maine, Late Quaternary morphogenesis of a marine-limit delta plain in southwest Maine, morainal banks and the deglaciation of coastal Maine, and glacial dynamics, deglaciation, and marine invasion in southern Quebec. Material originated at a March 1998 symposium held in Maine at the 33rd Annual Meeting of the Northeastern Section of the Geological Society of America.

The Far Northeast, a peninsula incorporating the six New England states, New York east of the Hudson, Quebec south of the St. Lawrence River and Gulf of St. Lawrence, and the Maritime Provinces, provided the setting for a distinct chapter in the peopling of North America. Late Pleistocene Archaeology and Ecology in the Far Northeast focuses on the Clovis pioneers and their eastward migration into this region, inhospitable before 13,500 years ago, especially in its northern latitudes. Bringing together the last decade or so of research on the Paleoindian presence in the area, Claude Chapdelaine and the contributors to this volume discuss, among other topics, the style variations in the fluted points left behind by these migrating peoples, a broader disparity than previously thought. This book offers not only an opportunity to review new data and interpretations in most areas of the Far Northeast, including a first glimpse at the Cliche-Rancourt Site, the only known fluted point site in Quebec, but also permits these new findings to shape revised interpretations of old sites. The accumulation of research findings in the Far Northeast has been steady, and this timely book presents some of the most interesting results, offering fresh perspectives on the prehistory of this important region.

The summary indicates how a radiocarbon data base for the western basin of the Champlain Sea interprets the late glacial and early postglacial history of the Ottawaw area.
