About Alunite GroupHide

Formula:
A0.5-1 B3[SO4]2(OH)6
Trigonal hydrous sulfates, where:

A = K+, Na+, NH4+, Ag+, Pb2+, Tl+, Ca2+, H3O+, Ba2+;
B = Fe3+, Al3+, also Cu2+ in combination with Al3+ specifically in osarizawaite;

In general, to maintain overall charge balance, A+ cations are present up to 1 apfu, whereas A2+ cations are present up to 0.5 apfu; osarizawaite is an exception, where charge balance for one A-site Pb2+ is maintained by the combination of (Al2Cu2+) in the B-site.
A subgroup of the Alunite Supergroup.
The most common members are jarosite and alunite sensu stricto.

See also the Plumbogummite Group and Beudantite Group.

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.
