Abstract
The southeastern sector of the Laurentide Ice Sheet experienced an important episode of ice volume reduction during transition from marine isotope stage 4 to 3, which led to the development of a large glacial lake in the northward-flowing Chaudière and St-Francois River valleys (Québec). This episode is associated with glacial Lake Gayhurst and is reflected by locally thick accumulations of glaciolacustrine sediments. Here we constrain the depositional age for these fine-grained sediments using a new approach in optical (IRSL) dating based on bulk sediment aliquots. Our chronology assigns this interstadial event to a period between ca. 60 to 35 ka.
