Using physiographic evidence, geologists have endeavoured for a long time to employ fossil coral reefs as ancient sea-level gauges. A further step in this direction has been the production of a numerical chronology of sea-level changes from reefs, through radiometric dating of corals and
molluscs that preserve their original mineralogy. Recent oxygen and carbon isotope abundance studies in reef material from a sequence of uplifted late Quaternary coral reefs on the Huon Peninsula, New Guinea,...[Show more]
