...) presented a thorough review of both minerals and synthetic compounds with kröhnkite-type chains and divided them into six different structure types (Types A to F). Type A is triclinic ( P ) and includes collinsite, talmessite, cassidyite, parabrandtite, roselite-β, and gaitite; Type B is also triclinic...

It is divided into the brandtite group, including the species brandtite, dobšináite, kröhnkite, roselite, rruffite, wendwilsonite and zincroselite, the collinsite group, including the species anorthoroselite, cassidyite, collinsite, gaitite, hillite, nickeltalmessite, parabrandtite...

... (brandtite and parabrandtite) occur as both structure-types. All minerals (except kröhnkite) have Ca as the dominant X -cation. The X -cation may be monovalent (Na in kröhnkite) or divalent (Ca in all the other minerals of these three groups). Fleck & Kolitsch (2003) , Kolitsch & Fleck...

Thus, the discovery of rruffite begs the question whether rruffite, like other arsenate minerals of the roselite group, undergoes a polymorphic transformation...
