LUMINESCENCE DATING OF RECENT DUNES ON INCH SPIT, DINGLE BAY, SOUTHWEST IRELAND

Fifteen samples of dune sand, and three samples from a core taken in t he beach face, were collected from a sand spit which protrudes into Di ngle Bay in Southwest Ireland. The potassium-rich feldspar grains from the samples were dated using a single aliquot luminescence protocol f or infrared stimulated luminescence (IRSL) signals. No ages over 600 y ears were obtained, which demonstrates the youth of the dune forms cur rently observed. The youngest ages were about 150 years old, but for t hese samples the scatter in the equivalent dose obtained as the mean o f 18 measurements was higher than for the older samples.
