Name:
For the carbonate contents and it's relationship to cyanotrichite
Cyanotrichite Group.
A mineral closely related to Cyanotrichite, but often misidentified (old published X-ray powder diffraction data of both species are unreliable; much improved data were recently given by Hager et al. (2009)).
Although the mineral shows a close relation to cyanotrichite, it is even more closely related to camérolaite.
PXRD and chemical analysis are necessary for a correct identification.
Previously, it was thought that quantitative measurements of the carbonate contents were needed for a correct identification, and that qualitative tests were not conclusive, because cyanotrichite can apparently contain small amounts of carbonate. However, Hager et al. (2009) suggest that there is no evidence for solid solution between cyanotrichite and carbonatecyanotrichite; it is also evident that some carbonatecyanotrichite specimens contain no sulfate. This explains previous contradictory results from PXRD and chemical studies of given samples.
The nomenclature situation is still complicated because the crystal structures of neither mineral is presently known.
Visually similar to Khaidarkanite.
