Three lacustrine deposits from the Kingston Region were each sampled, radiocarbon- dated and analyzed stratigraphically for more than 50 parameters. The present study suggests the existence of an abundant aquatic vegetation in Atkins Lake, Grady Lake and in the Cataraqui River Marsh 11,100+270, 10,500+180 and 10,200+180 years ago respectively, bordered by a forest- tundra quite similar to the one prevailing today in the Canadian Low Arctic. Stratigraphic variations in pollen types such as spruces, pines and thermophilous hardwood trees suggest several climatic oscillations prior to colonial time in the Kingston Region. The quantitative distribution of 27 different molluscan species and forms from the Atkins Lake deposit does not correlate with the climatic fluctuations detected by pollen analysis. The mollusc abundance associated largely with the marly sediments seem to be inversely proportional to the paleoproductivity of the deposit which was estimated by the sedimentary chlorophyll degradation products. Ill The bottom surface sediments of nine Gatlneau Area lakes were analyzed chemically so as to facilitate geochemical interpretation of the three fossil sites from the Kingston Region. The results show that the trophic level of a lake can be grossly characterized by the composition of its sediments. The stratigraphic composition of each deposit demons trates the high sensitivity of lakes to allochthonous and autochthonous ecological changes. IV RESUME Le but principal de cette etude multidisciplinaire de depots lacustres d'age quaternaire superieur est de retracer 1*evolution limnologique des lacs au moyen de trois methodes paleoecologiques (palynologie, malacologie et geochimie). Des carottes de sediments provenant de trois depots de la region de Kingston ont ete prelevees, datees au moyen du radiocarbon et analysees stratigraphi- quement pour plus de 50 parametres chacune. Cette etude revele 1'existence d'une vegetation abondante dans les lacs Atkins et Grady ainsi que dans le marais de la riviere Cataraqui il y a 11,100+270, 10,500+180 et 10,200+180 annees respectivement. Pendant le retrait de la calotte glaciaire, une vegetation hemiarctique a graduellement envahi la region de Kingston, Les variations stratigraphiques dans les spectres sporo-polliniques demontrent que plusieurs fluctuations climatiques se sont succedees avant l'avenement de la colonisation. La distribution quantitative de 27 differentes especes et formes de mollusques des sediments du lac Atkins ne semble pas etre attribuable aux diverses fluctuations climatiques. La distribution stratigraphique des mollusques, associee principalement a. des sediments marneux, est inversement proportionnelle a la paleoproductivite du lac determinee par le biais des produits de degradation de la chlorophylle , V Les analyses chimiques des sediments de surface preleves dans neuf lacs de la region de la Gatineau et qui semblent refleter le niveau trophique de ces lacs ont facilite 1'interpretation geochimique des trois depots du Quaternaire superieur de la region de Kingston. Les analyses des profils des trois depots lacustres demontrent que la productivity des lacs est fortement influencee par les changements ecologiques allochtones et autochtones.
