The Mineral Spectroscopy Server

Provides on-line information on the color of minerals; spectra of minerals (VIS, NIR, IR, Raman); Data files as ASCII (wavelength, absorbance) pairs; and an extensive reference list to optical spectra of minerals sorted by mineral and author and references to hydrous components in minerals..

Plus information on a variety of special topics including manganese oxides; desert varnish; and the ametrine variety of quartz.
