TITLE: Chrysotile HS323 DESCRIPT
MINERAL: Chrysotile (Kaolinite-Serpentine Group)
CURRENT_SAMPLE_LOCATION: USGS Denver Spectroscopy Laboratory
Chrysotile was not available in grain sizes greater than 200µm and was not sieved to grain sizes less than 200µm because of its carcinogenic character.
This is a pure chrysotile. Sample analysis by Norma Vergo.

COMPOSITIONAL_ANALYSIS_TYPE: None # XRF, EM(WDS), ICP(Trace), WChem
Several attempts were made to chemically analyze this sample by XRF. However, sufficent quantities were not available to perform a reliable analysis.
Microscopically this is a pure chrysotile. Fibers avg. diameter is about 8 µm from optical observations. G. Swayze.
