Collection of seismic reflection data from continental margins and ocean basins surrounding North America makes it possible to estimate the amount of material eroded from the area formerly covered by Laurentide ice sheets since major glaciation
began in North America. A minimum estimate is made of 1.62 10 km, or an average 120 m of rock physically eroded from the Laurentide region. The importance of continental glaciation as a geomorphic agency in North America may have to be reevaluated
The Late Pleistocene Laurentide Glacier : Th/U dating of its major fluctuations and 18O range of the ice
This geochemical study provides a chronological framework for the Laurentide Ice Sheet inception and its major fluctuations, and also some indication of the isotopic composition of the ice.
Volume and routing of late-glacial runoff from the southern Laurentide Ice Sheet
The major objective of this research was to quantify the outflow of meltwater and precipitation-generated runoff from the region that lay on and adjacent to the southern margin of the Laurentide Ice Sheet, during a major period of glacial melting
Geological models for the configuration, history and style of disintegration of the Laurentide ice sheet in Models in geomorphology.
Presents models derived from current glacial geological information on three aspects of the Laurentide ice sheet : its configuration and centers of outflow| the latter part of its history of waxing and Waning and the style of its final deterioration
The effects of the Laurentide ice-sheet on North American climate during the last glacial maximum in La calotte glaciaire laurentidienne = The Laurentide ice sheet.

L'analyse pollinique des sédiments de trois lacs situés au sud-est du parc des Laurentides a permis de retracer les étapes de la recolonisation végétale post-wisconsinienne. Bien que les diagrammes révèlent des périodes de plus grande abondance de
Laurentide ice sheet extent inferred from stable isotopic composition (O, C) of ostracodes at Toronto, Canada
The data of this paper show the potential for using isotopic analyses of ostracodes to learn about the isotopic composition of terrestrial meltwater from the Laurentide Ice Sheet. These midcontinent data are especially valuable because they help
Unstable behavior of the Laurentide ice sheet over deforming sediment and its implications for climate change
The A. proposes that rapid oscillations of the Laurentide ice sheet margin are not climatic in origin but instead reflect inherent instability associated with deforming sediment dynamics. Such behavior would have played a critical role in affecting
Importance of the regelation process to certain properties of basal tills deposited by the Laurentide ice sheet in Iowa and Illinois, USA
Recent stratigraphic studies have characterized the sequence and nature of tills deposited in Iowa and Illinois by Quaternary Laurentide ice sheets. Basal tills within the sequence are each dominated by matrix-size materials and exhibit uniform
Paleoenvironments along the eastern Laurentide ice-sheet margin and timing of the last ice maximum and retreat in La calotte glaciaire laurentidienne = The Laurentide ice sheet.
scientifique. Les Québecois sont très attachés à cet oekoumène comme le montrent la peinture et la littérature. Au cours du siècle dernier, le terme Laurentides s'est déplacé tant au Québec qu'au Canada, sémantiquement et spatialement, ce qui a entraîné une
Evidence for coalescence of Laurentide and Rocky Mountain glaciers east of Glacier National Park, Montana
Evidence indicates that Laurentide and Rocky Mountain piedmont glaciers coalesced in the Willow Creek drainage east of Glacier National Park. Based on relative soil development, alpine tills in the North Fork of the Milk River could be two ages
in unstable proglacial environments. In particular, granite erratics, probably ice-rafted, commonly mantle landforms not constructed by the Laurentide glacier(s).
