dc.description.abstract Marl and carbonized organic material, deposited during the Nipissing Great Lakes stage, rests in direct superposition on lower Algonquin (Payette ? stage) beach gravels, at Wasaga Beach, Ontario. Five radiocarbon dates from the marl, (M-1024) 5840±350 B. P., (M-1025) 5270±350 B. P., (M-1026) 5740±250 B. P., (M-1027) 12,250±150 B. P., and (M-1028b) 20,000±2,000 B. P., vary widely and apparently show the effect of contamination by the addition of "dead" carbon from adjacent Paleozoic carbonate rocks. A sixth date, (M-1028a) 5120±400 B. P., obtained from a charcoal layer on top of the gravel, is believed to be correct and records a time near the end of the interval during which waters were rising to the Nipissing level from the preceeding low Stanley stage. The marl deposit has yielded a molluscan fauna consisting of 22 species. The mollusks indicate a quiet, lacustrine environment, with abundant aquatic vegetation. Plant materials from these deposits were too highly degraded to provide much useful paleoecologic information. en_US
