OLIVINE LABORATORY INFRARED ABSORBANCE SPECTRA V1.0

Laboratory measurements quantifying the effect of Fe substituting for Mg in olivine are necessary to distinguish compositional from temperature, grain size and grain shape effects in observational data. This dataset presents room temperature (18-19 degrees Celsius) diamond anvil cell thin film absorption spectra of a large suite of olivines evenly spaced across Mg and Fe compositions at infrared wavelengths. In each file, the left column is the frequency in wave numbers (units: cm**-1). The right column is the chemical absorbance (common logarithm based).
