The arctite supergroup has been established; it currently includes nine
mineral species. The supergroup is divided into the zadovite group
(alternation of tetrahedral layers and antiperovskite layers – TA) and
the arctite group (alternation of tetrahedral layers and triple
antiperovskite layers – TA
The fillowite group has been established; it currently includes four mineral
species. The chemical formulae of the minerals of the fillowite group have
been uniformed, based on nine (

After the approval of shuiskite-(Cr) (IMA no. 2019-117; see above), and
considering that the nomenclature of the pumpellyite group is based on
suffixes, it was decided to change the name of the mineral shuiskite to
shuiskite-(Mg). The rationale in the nomenclature of the pumpellyite group
is that the root name depends on the dominant – always trivalent – cation at
