NOMENCLATURE PROPOSALS APPROVED TO SEPTEMBER 2009
IMA 07-D ALUNITE SUPERGROUP
The recommended nomenclature of the alunite supergroup is accepted. Minamiite is renamed natroalunite-2R, and beaverite is renamed beaverite-(Cu). Orpheite is discredited because it is identical to P-rich hinsdalite.

IMA 08-D SLAVIKITE
The proposed revision of chemical composition and crystal structure of slavikite is accepted. The formula of slavikite now becomes (H3O+)3Mg6Fe15(SO4)21(OH)18·98H2
O.
OLDER NOMENCLATURE MODIFICATIONS APPROVED TO SEPTEMBER 2009
IMA 07-E HASTITE
The mineral hastite, orthorhombic CoSe2 (marcasite group), is discredited. The type material has been shown to be ferroselite, FeSe2
.
IMA 08-B β-DOMEKYITE
Proposal IMA 68-3 is nullified. The name “wrightite” is discredited and the original name β-domeykite is revalidated.
IMA 08-C KHINITE and PARAKHINITE
Khinite and parakhinite are polytypic. As a consequence, khinite is renamed khinite-4O, and parakhinite is renamed khinite-3T.

Hallo,

IMA No. 2009-046 

seltsam, Turmalingruppe aber monoklin? Und wenn Turmalingruppe wo ist dann der Unterschied zu einem Schörl-Dravit Mischkristall?

Gruß
Berthold

[Stefan]

Damit können wir trigonal aus der Turmalingruppe streichen...

Uwe Kolitsch arbeitet gerade an einem F-Analog zu IMA2009-046 (Quelle: Mindat).
