Description
The absorption spectra of the olivine particles of different Mg/Fe content were measured in the infrared spectral region between 5 and 100{mu}m, while the particles were continuously cooled down to 10K. Measurements independently carried out on different samples of synthetic forsterite, natural olivine, and synthetic fayalite at laboratories in Kyoto and Jena. The positions of the olivine infrared bands were measured for these samples in detail at up to seven individual temperatures in the interval between 300K and 10K. According to the different widths of the olivine bands in different wavelength regions, spectral resolutions of 2, 1, 0.5, 0.25, 0.2, and 0.125cm^-1^ were used in order to measure the band positions with high accuracy.
