XRD Analysis

40 kV - 30 mA, 7.3-6.5 keV Reference: JCPDS #30-1203 (natrojorosite) Found: natrojarosite Comment: GDS100 is sharp, indicating good crystallinity. GDS is distinctly sharper, with better resolved peaks. Good correspondence with the JCPDS data. No additional reflections observed. J.S. Huebner, J. Pickrell, and T.
