END_SAMPLE_DESCRIPTION.
XRD_ANALYSIS:
40 kV - 30 mA, 6.5-9.5 keV
File: azur316.out, *_mdi (smear mount on quartz plate)
References: JCPDS #11-682
Found: Azurite
Comment: Sharp peaks with distinct alpha1-alpha2 separation indicate good crystallinity. Three weak to very weak reflections are not present in the JCPDS listing but are present in Huebner's reference pattern for azurite from Bisbee, AZ.
