TIDAL? RHYTHMITES OF THE LATE WISCONSINAN CHAMPLAIN SEA
Numerous preserved basin marginal facies of the Champlain Sea have been identified throughout northwestern Vermont, northeastern New York and eastern Ontario, which are primarily represented by well-preserved littoral facies, including frequent topset delta facies. The study of these various sedimentary facies aims to identify the tidal signature that may be preserved within characteristic rhythmic bedding expressed at these many localities. Analysis of these tidal signals allows for characterization of the local tidal regime as well as the determination of the sediment accumulation rates of these various littoral basin-fill sediments.
