END_SAMPLE_DESCRIPTION.
XRD_ANALYSIS:
40 kV - 30 mA, 7.0-9.5 keV
File: plogo675.out, -.mdi (edge = random mount)
References: Huebner's reference patterns, particularly of a
phlogopite crystal from Burgess, Ontario; S. W. Bailey (1988,
MSA Reviews 13)
Comment: Only moderately well crystallized (compare with WS-496). Position of the (3T 30-30) or (1M 060) reflection at 1.535 Angstroms consistent with phlogopite (Mg=100). Three unindexed reflections at 1.64, 1.61. and 1.58 Angstroms also appear in the reference pattern and in WS-496.
