Summary

Tables of U- and Th-isotopic data used to calculate uranium-series age estimates and initial 234U/238U activity ratios as well as 87Sr/86Sr, δ13C, and δ18O for samples of phreatic speleothems from Wind Cave National Park and U- and Sr-isotopic compositions of waters from the southern Black Hills of South Dakota, USA

Purpose

Isotopes of U and Th from phreatic speleothems exposed in lower passageways at Wind Cave were used to better establish the history of water table fluctuations over the past million years. In addition, Sr-, U-, C-, and O-isotopes from dated calcite samples were obtained to evaluate potential shifts in paleo groundwater composition compared to modern groundwater compositions from different aquifers in the region. Results are used to understand processes contributing to water resources at Wind Cave National Park and the regional hydrogeologic responses to Plestocene climate shifts.
