Baryte Visible Spectra (3-00 - 1100 nm)
Baryte would be colorless if pure, but radiation-damage centers
commonly
cause color. O- (in some blue
crystals), SO3-
(in
some honey-yellow and blue crystals), and SO2-
(in
yellow crystals) centers have been identified in baryte by Bartoshinsky
et al. (1991)
Baryte absorption spectrum
- baryte
spectrum;
from Meikle Mine, Carlin, Nevada. Plotted as 20.0 mm thick. The
spectrum
of this honey-yellow
, mildely radioactive material shows weak bands near 435 nm ascribed to
the SO2- ion color
center
mentioned above. Data Files: E||a;
E||b;
E||c.
- baryte spectrum;
GRR 3243, from Stoneham, Weld County, Colorado. Plotted as 7.45 mm
thick. The spectrum of this pale blue crystal
shows bands near 604 and 629 nm with a weak component near 725 nm. This
type of spectrum has been associated with an O-
ion by Bartoshinsky et al (1991).
