"Submitted to Journal Radioanal. Nucl. Chem. This copy is to provide information prior to publication." "April 1988." Includes bibliographical references. "Lead-210 dates are assigned to a sediment core retrieved from McKay Lake, Ottawa, Canada. Sediment mixing is found to have little, but discernible, influence on the age/depth profile. Consideration of mixing yields lower estimates of the derived ages, in agreement with the prediction based on a mathematical model. The inferred dates support the previous assignments based on Ambrosia & horizon and the known occurrence of a catastrophic event. The procedures used in the calculation of the age profiles are fully described"--Abstract. Includes abstract in French. gccst Sediments gccst Lakes Shukla, Bhagwan S. (Bhagwan Sahay), 1943- author.
