Mineral:  Tremolite Ca2(Mg,Fe+2)5Si8O22(OH)2

Sample No.:  tremol.2

XRD Analysis:  Tremolite plus a trace of mica.

Chemistry:  Microprobe analysis showed the sample to be 
homogeneous within and between grains.  It has extremely high soda 
and potash for a tremolite.  Thus, chemically it is more like richterite 
than tremolite.  Average of 10 analyses:
