The Mineral Spectroscopy Server
On-line information on the absorption
spectra and color of
minerals.
Information on the origin of color in
minerals and gems
Data files available as ASCII
(wavelength, absorbance)
pairs
[more than a thousand files]
Images of selected mineral spectra
Extensive references to mineral optical
spectroscopy [more
than 600 references]
PLUS
information on manganese dendrites [They
are not
pyrolusite!]
information of desert varnish
information on ametrine [amethyst - citrine bicolored
quartz]
information on painite [ formerly one of the rarest
minerals]
Go to the
Mineral
Spectroscopy Server
Raman Spectra on the
Mineral Spectroscopy Server have been placed with the
RRUFF Project,
a project under the direction of Professor Robert Downs at the
University of Arizona, in collaboration with Caltech Mineralogy.
Numerous Caltech infrared ATR spectra of minerals are also being placed
on this
site. The RRUFF Project contains the largest collection of quality
Raman spectra of minerals available from any source. It also has one of
the largest (but still incomplete) collections of mineral ATR data.
