| Translated title: | Reservoir effect on ¹⁴C ages of Champlain Sea at the Pleistocene-Holocene transition: revision of the chronology of ice retreat in southern Québec. |

| Abstract: | Integrates new ¹⁴C ages from central St. Lawrence valley, notably Mont Saint-Hilaire, into stratigraphic/palynostratigraphic framework. Re-evaluates chronology of regional deglaciation and invasion of Champlain Sea. Compares with Laurentide, Great Lakes and New England chronologies. Uses dated terrestrial plant macrofossils and pollen content of underlying postglacial lake sediments to date local ice retreat around 11,250 ¹⁴C yr BP. Cross-dates with Lac Hertel marine sediments show 1700 ¹⁴C year difference, due mainly to effect of old carbon on upper shallow waters of Champlain Sea. Dates local and regional marine invasion, confirming New England varve chronology. Concludes entire St. Lawrence valley was deglaciated within 1000 ¹⁴C years. Shorter and younger Southern Québec ice retreat chronology prompts major revision of palaeohydrological events. |
