SUMMARY

Two samples of plant-rich limy sand collected from the 9- and 11-ft.-level of the Heron Island cay were subjected to 14C dating. Uncertainties related to secondary changes and contaminations, and the unknown transportation history of the woody material prior to accumulation at Heron Island, in combination with the relatively young age of the carbon, did not result in 14C values useful for correlation and absolute dating purposes.
