(300 - 900 nm)
Image of the ellenbergite
absorption spectrum
- ellenbergite
spectrum;
from the Dora Maira Massif, Western Alps, Italy. Replotted from the
original data in Chopin
& Langer (1988) Bulletin de Mineralogie 111, 17-27.
Plotted as 1.0 cm thick. The color of this material is reported to come
from intervalence charge transfer between face-sharing
Fe2+
- Ti4+
octahedra.
