Sample Description
Sample was ground in an alumina mortar and pestle and wet sieved with methanol into grain size fractions. King, T.V.V. and R.N. Clark, 1989, Spectral Characteristics of Chlorites and Mg-Serpentines Using high-Resolution Reflectance Spectroscopy. Jour. Geophys. Res., 13.997-14,008. Grain size fractions are indicated by the extension after the sample number: .d = less than 30µm .c = 30-45µm .b = 60-104µm .a = 104-150µm IMAGE_OF_SAMPLE: NO PHOTO
