The ESR dating of molluscs has been extended to terrestrialgastropods from two sites in the Missisippi Valley, USA. The sites have been dated by other methods, although one is not definitively characterized. ESR results showed good agreement with the well-dated site, and suggested the younger of two
Due to relatively low thermal stability of radiation-induced centres in biogenic carbonate of subfossil molluscs (mean life r =3.7 x 105y at 10C, g=2.0012) correct dating of the latter by means of ESR-speetroscopy without considering natural relaxation of absorbed palaeodose may prove rather problem
