Palaeoecology of a bank section of the Riviere Saint-Charles : Macrofo ssil analysis of the archaeological site named Grande Place in Quebec City. Archaeoecological research downtown Quebec City has been realize d for the identification of 1) different occupation phases since the a rrival of the Europeans, 2) location of Stadacone village, a native ag glomeration mentionned by Jacques Cartier in his travel diary. Detaile d paleoecological analysis of an organic section allowed the geomorphi c reconstruction of the Riviere Saint-Charles paleoriver bank. The ori gin of the analyzed sequence is from a depression in which organic dep osits accumulated as a consequence of drainage deterioration caused by a 2 m rise of relative sea level 2000 years ago (Mitis transgression) .
