Sr and U concentrations and radiogenic isotope compositions (87Sr/86Sr, 234U/238U) of thermal waters, streamflow, travertine, and rock samples along with U-Th disequilibrium ages for travertine deposits from various locations in Yellowstone National Park, USA (ver. 2.0, August 2024)
Radiogenic isotopes of strontium and uranium (87Sr/86Sr and 234U/238U) are useful tracers of water-rock interactions.  Sr isotopic signatures in groundwater are derived by dissolution or exchange with Sr contained in aquifer rock whereas U isotopic signatures are more controlled by physicochemical and kinetic …
