U-series and Sr-isotope data release supporting Tufa and Water Radiogenic Geochemistry and Tufa Ages for Two Karst Aquifers in the Buffalo National River Region, Northern Arkansas

This dataset includes tables of U- and Th-isotopic data used to calculate uranium-series age estimates (230Th/U method) and initial 234U/238U activity ratios for samples of tufa mounds formed by groundwater seepage. In addition, data include 87Sr/86Sr and 234U/238U values determined for spring discharge and streamflow collected from sites in the vicinity of Buffalo National River.
