Raman study of samples from the May 2001 FIDO test site

Blind field tests of the FIDO (Field Integrated Design & Operations) rover were conducted Apr 30th-May 11th, 2001 at Soda Mountain, CA. We analyzed samples CL01-1 through CL01-13 from that site in the laboratory by Raman spectroscopy to provide a data set that could be compared with results from other instruments.

fido2001_2.jpg (626319 bytes) Minerals found in rocks:

Plagioclase (K-feld, Cristobalite/qtz, SiO2 galss);
Biotite-Phlogopite (stilphnomalene?);
Hornblende (magnesiohastingsite);
Clino- & Orthopyroxene;
Hematite (magnetite, cassiterite, anatase, and brookite);
Calcite/aragonite;
Montomorillonite;
Alunite (anhydrite);
Graphitic carbon.

Minerals  in soil different from rocks:

More Qtz than cristobalite, more K-feld than plag.
