The reflectance spectra of minerals are studied as a function of spectral resolution in the range from 0.2 to 3.0 {mu}m. Selected absorption bands were studied at resolving powers ({lambda}/{Delta}{lambda}) as high as 2,240. At resolving powers of approximately 1,000, many OH-bearing minerals show diagnostic sharp absorption at the resolution limit. At low resolution, some minerals may not be distinguishable, but as the resolution is increased, most can be easily identified. As the resolution…

High-resolution reflectance spectra of Mars in the 2.3-μm region: evidence for the mineral scapolite

Spatially resolved reflectance spectra of Mars in the 2.2- to 2.4-μm spectral region were obtained in August 1988 using the NASA 3-m Infrared Telescope Facility. The spectra show weak absorption

Mineral Interpretation Discrepancies Identified between Infrared Reflectance Spectra and X-ray Diffractograms

Both XRD and reflectance spectroscopy can be useful, but care should be given to the limitations of the interpretation process.


In comparison with multispectral image data, hyperspectral (HS) imagery with higher spectral resolution provides sufficient spectral resolution to describe diagnostic absorption signatures. Specific
