Abstract

Fossil mollusk shells from late Quaternary deposits in Southern Nevada were radiocarbon dated to determine the age of paleogroundwater discharge events and to establish minimum 14C ages of paleogroundwater. Shells of the terrestrial taxa Vallonia sp. and Succineidae returned 14C dates consistent with those on organic material in the same stratigraphic position. The aquatic taxa Gyraulus parvus and Gyraulus circumstratus returned the oldest dates within each unit sampled. These results show that 1) fossil Vallonia and Succineidae are useful in dating deposits in which no other radiocarbon-datable material is available, and 2) Gyraulus sp. select micro habitats with the most 14C deficient water, providing minimum ages of groundwater in the area during the last glacial period.
