Wyartite Visible Spectra (400 - 1000 nm)
Image of the wyartite, CaU5+(UO2)2(CO3)O4(OH)·7H2O, absorption spectrum
- Wyartite
spectrum;
from
Africa, 0.0056 mm thick sample. This is an interesting mineral because
it contains both U5+
and UO22+. The
orientations of the spectra are not known because the sample was lost
before
they could be determined. It happens some times when working
with
small, delicate samples.......
