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.
Minerals structurally related to group:

Other Information
Notes:
Small amounts of Si4+ can apparently substitute for P5+ with valence compensation probably being accomplished by a simultaneous substitution of Zr4+ and U4+ for Y3+.
Health Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
