Isotope analyses (234U/238U, 87Sr/86Sr, δ13C, and δ18O) and U-series disequilibrium ages for speleothem, water, and rock samples associated with Fitton Cave, Buffalo National River, Arkansas, USA

공공데이터포털

This data release contains tabular data (comma-separated-value files) of natural radiogenic isotopes of strontium, uranium, and thorium for samples of modern water, speleothems, associated with Fitton Cave, north central Arkansas, as well as rock that host the cave deposits. In addition, U-series ages (230Th/U dates and model 234U/238U dates) are calculated from those data for subsamples of speleothems. Stable isotopes of oxygen and carbon are reported for a subset of the stalagmite samples. Sample locations and descriptions as well as specific sub-sample imagery and narrative explanations are included as information supporting the analyses. Selected results are depicted as data plots in an accompanying Excel spreadsheet for non-interpretive illustration.

Stable carbon and oxygen isotope paleoclimate records of U.S. Geological Survey-collected samples from Devils Hole and Devils Hole Cave 2, Nevada

공공데이터포털

In support of paleoclimatology investigations, samples of mammillary calcite, calcitic folia, and flowstone were collected by the U.S. Geological Survey in Devils Hole and Devils Hole Cave 2, Nevada, between 1983 and 1996. These samples came from about 60 m below to 9 m above the modern water table in these caverns. To determine δ18O and δ13C time series spanning the interval 567.7–4.5 ka, more than a thousand samples were milled and analyzed for their δ18O and δ13C values. To determine time-series ages, more than a hundred samples were analyzed using uranium-series dating. Many of these measurement results have not been published. Herein, we provide previously unpublished δ13C and δ18O values, and we provide unpublished background data for selected uranium-series ages.
