Aspects of carbonate mineralogy can be determined by the use of near-infrared spectra. We have carried out an experimental study of calcite and dolomite in carbonate rocks with near-infrared spectra and XRD analyses. A direct linear correlation was found between the absorption band positions and the calcite/(calcite + dolomite) ratios of carbonate rock samples. It may be useful for determining the calcite and dolomite contents of unanalyzed specimens, and for surface reflectance mapping by hyperspectral remote sensing.
