Comparison of averaged reflectance spectra among the bulk samples, aggregate samples, and individual grains. Averaged a absolute reflectance and normalized reflectance with continuum at 2.6–4.1 μm for b bulk samples, c aggregate samples, and d individual grains. Beam spot size of bulk samples is approx. 6 mm, and that of aggregate samples and individual grains is approx. 1 mm. Relative standard deviation (RSD, %) is also shown in b, c, and d
