Mineral:  Olivine (Fo92) (Fe+2,Mg)2SiO4

Sample No.:  olivine.11

XRD Analysis:  Pure forsterite.

Chemistry:  Microprobe analysis of five grains showed the sample to 
be homogeneous within and between grains. Average of 10 analyses 
shows that the sum of the divalent cations is too high, but Fo content 
is about 92 mole percent:

SiO2	40.27
