Abstract

Multiple varve counts over common intervals in four parallel cores permit estimation of the precision of the Elk Lake varve chronology. At the 95% confidence level, the imprecision of the counts averages 12%. External evidence and comparison of independent varve counts suggest that the accuracy of the varve chronology is well within this limit. Magnetic susceptibility is shown to be an exceptional tool for determining stratigraphic correlations, allowing unambiguous matching of all cores used.
