A combination of hyperspectral imagers are used for optimized results. The table provides a guideline to spectral responses of different mineral groups.


Good – good characteristic signatures to enable direct mineral identification from the spectra.

Moderate – Characteristic mineral signatures are obtained from the spectra but analysis may be challenging in certain instances.

Non-diagnostic – Spectral signatures do not allow identification. Still, spectral discrimination may allow identification.

TBD – Spectral signatures are unknown or uncertain.
