Sample Description

Sample was prepared from a chemical reagent of Fe2O3. Fine grained powder was mixed with water and an eye-dropper was used to deposit a thin coating on a microscope glass thin section. The sample was dried over night and them measured spectrally. Our goal was to unsaturate the goethite bands and mimic the spectral absorptions found in natural goethite coatings.
