The Shoreline Relation Diagram: Physical Basis and Use for Predicting Age of Relative Sea Levels (Evidence from Arctic Canada)

A shoreline relation diagram for Arctic Canada is constructed from the equation of the form of postglacial uplift. This operation in itself indicates that the shoreline relation diagram represents a valid concept. The diagram is then used to predict the age and elevation of marine limits, glacial lake strandlines, and lower relative sea levels. A comparison of predicted and observed values suggests that the shoreline relation diagram presented in the paper functions efficiently as a chronological forecaster that can complement and extend late-glacial and postglacial chronologies. The workings of the diagram are such that a few selected radiocarbon dates can be used to establish an extensive and detailed chronology.
