3 Nomenclature/classification proposals approved in

February 2020


Arctite supergroup

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 – TA3).


Fillowite group

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 (PO4) groups pfu, as follows: fillowite, Na3CaMn2+11(PO4)9; johnsomervilleite, Na3CaFe2+11 (PO4)9; chladniite, Na3CaMg11(PO4)9; galileiite, Na3Fe2+Fe2+11(PO4)9. Stornesite-(Y) has been discredited since it is equivalent to Y-bearing chladniite.


Magnetoplumbite group

The magnetoplumbite group has been established; it currently includes 11 mineral species. Minerals of the magnetoplumbite group have the general formula A[B12−x]O19−y, with 0 ≤x≤1 and 0 ≤y≤2. The group is divided into subgroups, based on the dominant Acation: magnetoplumbite R. Miyawaki et al.: CNMNC Newsletter 54 283 subgroup (A=Pb), hawthorneite subgroup (A=Ba), and yimengite subgroup (A=K). Hibonite-(Fe) has been renamed to chihuahuaite.


Walentaite group

The walentaite group has been established; it currently includes four mineral species. Minerals of the walentaite group have the general formula [(A1,A10,A2,□)(H2O)n][BxAs3+3−xM1(M2)2(TO4)2(O,OH)7]. The group is divided into subgroups based on the dominant Tcation: walentaite subgroup (T=P), and halilsarpite subgroup (T=As).


4 Nomenclature/classification proposals approved in

March 2020

IMA 19-I: redefinition of fairbankite

Proposal 19-I is accepted, and fairbankite is redefined. The previously accepted formula was Pb2+Te4+O3. Now it has been proven that sulfate group is an essential constituent and the formula has been changed to Pb2+ 12 (Te4+O3)11(SO4).

Renaming of shuiskite

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 M2, whereas the suffix depends on the dominant cation at M1. Currently the root names are as follows: pumpellyite (M2=Al), julgoldite (M2=Fe3+), shuiskite (M2=Cr), okhotskite (M2=Mn3+), and poppiite (M2=V3+). The valid species are as follows: pumpellyite-(Mg), pumpellyite-(Fe2+), pumpellyite-(Fe3+), pumpellyite-(Mn2+), pumpellyite-(Al), julgoldite-(Fe2+), julgoldite-(Fe3+), julgoldite-(Mg), shuiskite-(Mg), shuiskite-(Cr), okhotskite, and poppiite. The latter two minerals are (still) without suffix as they stand alone with their root name.

oliverOliver:
ist der Pošepnýt damit jetzt doch ein anerkanntes Mineral?

Stefan:
Das sieht so aus  - Ja

oliverOliver:
hmm - das führt jetzt aber sicher wieder zu Verwirrung.
Der Pošepnýit der vorher im Lexikon war (kein anerkanntes Mineral/Mineralstatus fragwürdig) war ja ein fossiles Harz, das aus Kalifornien (?) beschrieben worden war - jetzt wird der gleiche Name für ein (anerkanntes) Mineral der Tetraedritgruppe vergeben - finde ich zumindest ein wenig bedenklich .....

ist das nach den Nomenklaturregeln erlaubt ???

edit:
habs gefunden - auf Mindat ist die Literatur noch:
Schröckinger, J. (Freiherr) von (1877): Posepnyt, ein neues Harz aus Californien. Wien, Geol. Verhandl., 128-130.

Stefan:
Ah der Unterschied liegt im i

Posepnyt und Posepnyit

Posepnyt ist wieder im Lexikon und Posepnyit neu angelegt
