Mineral:  Kyanite Al2SiO5

Sample No.: kyanite.1

XRD Analysis:  Pure kyanite according to XRD.  (However, the slight 
amount of alteration product is clearly identifiable as kaolinite from 
its characteristic infrared hydroxyl bands near 2.7 micrometers.)

Chemistry:  Microprobe analysis showed hand-picked sample to be 
homogeneous within and between grains.  Average of 9 analyses:

SiO2	36.73
Al2O3	63.23
