Figure 2. Plot of reference laboratory spectra of calcite (blue) and dolomite (green) from Salisbury et al. (1991), converted to qualitative emissivity using Kirchoff's Law. The spectra convolved to ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) spectral resolution (Table 1) are shown in red. ASTER band centers are also shown. Note carbonate bending mode absorption features at band 14.
