Mineralogy, chemistry and isotope composition of silica sinter deposits from the Upper Geyser Basin, Yellowstone National Park: X-ray diffraction data

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-08-31T00:00:00Z
Sample Analyses: X-ray powder diffraction (XRPD) was carried out on samples UGB-TD-24 through UGB-TD-39 at the U.S. Geological Survey in Menlo Park, CA. Each sample was powdered using an agate mortar and pestle and packed into a shallow well (0.5 mm) aluminum XRPD mount with the knife edge of a spatula to ensure random orientation. Samples were scanned continuously at room temperature from 3.0° 2θ to 80.0° 2θ with a step size of 0.01° 2θ on a Rigaku Multiflex X-ray diffractometer with Cu-Kα radiation with an accelerating voltage of 40.0 kV and a filament current of 20.0 mA. Database Contents: The data files (Radiocarbon_Data_Supplementary.csv) contain the angle and intensity for samples UGB-TD-24, -25, -26, -27, -28, -29, -30, -31, -32, -33, -34, -35, -36, -37, -39. The entries in the data file appear in the following columns: A. Angle B. Intensity
