About Brackebuschite Supergroup
Formula:
M2+2M3+(TO4)2(OH)
A group of M2+-M3+-oxysalts (phosphates, arsenates, vanadates, sometimes also containing sulfate) where M2+ = Ca, Ba, Sr, Pb and M3+ = Al, Fe, Mn, ... (sometimes replaced by medium-small M2+ cations such as Zn2+, Fe2+, Cu2+). Named after the member brackebuschite.
Feinglosite is the only member containing a water molecule in its ideal formula.
Different space-group symmetries are known, confirming the close relation to fornacite and vauquelinite (U. Kolitsch et al., unpublished data).

Click on any node to view relationships. Formula-derived relationship network for the group members above. Use Find related species to add formula-neighbour species outside the current group view. Solid links show inferred chemical differences; dashed violet links show same-formula crystallographic differences. Hydration states are not treated as relationship changes. These relationships do not imply any real-world substitution reactions between these species.
