Abstract

Both aquatic and land snails are common in the geologic record, but their utility in dating is greatly resticted by their well-documented tendency to yield C 14 dates inconsistent with true C 14 ages. In this study, the AA. examine the use of C 14 ages from 1) small, previously unstudied, terrestrial snails to date hosting spring deposits and from 2) cooccuring aquatic snails to constrain groundwater travel times during the last glacial period. The results imply shorter groundwater travel times through aquifers in southern Nevada during late-glacial time
