Fig. 1: The absorption coefficient of fayalite αFa100 at ~1.1 GPa, measured in the laser-heated diamond anvil cell (solid spectra).
From: Olivine’s high radiative conductivity increases slab temperature by up to 200K
Eight overlapping black and blue spectra were measured before and after each of the high-temperature spectra (color-labeled), respectively. The dashed spectra are absorption coefficients of fayalite at room- and high temperature reported by ref. 30. The ICCD and InGaAs labels denote the spectral ranges recorded by these detectors. The vertical grey bar shows the region where our optical measurements are inaccurate due to the notch filter blocking the heating laser.
