Model near‐infrared optical constants of olivine and pyroxene as a function of iron content
Open accessAbstract
The imaginary coefficients of the complex index of refraction of olivine, low‐Ca orthopyroxene, and high‐Ca clinopyroxene are derived as a function of iron content and wavelength over the spectral region 0.4 to 2.5 μm from reflectance spectra of powders and Hapke radiative transfer theory. Reflectance spectra as a function of composition and grain size are computed and compared. I find that while spectral effects of variations in these parameters are similar, they are distinguishable. Variations in iron content do not explain all the observed spectral variations in the spectra of the samples investigated.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
