Description of Files: In each file, the left column is the frequency in wavenumbers (units: 1/cm). The right column is the chemical absorbance (common logarithm based). Fo0nat.dat is a tab delimited text file of the merged mid- and far-IR thin film laboratory absorbance spectra of a slightly impure fayalite, Fo0Te5, from Rockport, MA, USA.

Fo0syn.dat is a tab delimited text file of the merged mid- and far-IR thin film laboratory absorbance spectra of synthetic fayalite, Fo0 (syn). See Finch et al. (1980) and Hofmeister (1997) for more information on the sample itself.

Fo9nat.dat, Fo14nat.dat, Fo31nat.dat are tab delimited text files of the merged mid- and far-IR thin film laboratory absorbance spectra of slightly impure olivines, Fo9Te2, Fo14Te2, Fo31Te1 from Kiglapait Intrusion, Labrador [see also Morse 1996].

Fo41nat.dat is a tab delimited text file of the merged mid- and far-IR thin film laboratory absorbance spectra of an olivine Fo41 from Rustenberg, Transvaal, S. Africa. See Hofmeister & Pitman (2007) for breakdown of impurities.
