Abstract

In a tentative synthesis of statistical marine C chronology, isostatic and eustatic movements, continental glacial features and post-glacial marine limits, the paleogeographic evolution during the late and post-glacial times in eastern Canada, with special reference to Quebec, is here reassessed. Publications on these data, and field work by the authors, are used in the drawing of maps of isochrones of Laurentide ice retreat, maximum diachronous extension of post-glacial lakes and seas, emergence observed since 7,500 BP and of paleogeography at 10,000-10,500 BP. The post-glacial uplift of Quebec is reconsidered with new regional emergence curves. A time-space diagram from 15,000 to 8,000 BP indicates the main steps in the retreat of the Laurentide ice-sheet in eastern Canada and the associated marine episodes.
