Raman and Synchrotron X-ray Data of Sold Phases Used in Chromium Sequestration and Re-oxidation Experiments with Sand and Sediment from Hinkley, CA

This page contains (a) bulk synchrotron-based X-ray absorption spectra; (b) microbeam synchrotron-based X-ray fluorescence maps and spectra; and (c) microbeam Raman spectra (and corresponding optical images). These data were used to understand chromium, iron, and manganese valence and mineral residence in natural and synthetic mineral mixtures used in laboratory experiments designed to simulate dynamic conditions in an engineered aquifer system [see Izbicki and Groover (2018) and Miller and others (2020)].
