NOMENCLATURE PROPOSAL APPROVED IN AUGUST 2014

IMA 14-F: Laueite supergroup
The laueite supergroup has been formalized. Minerals of the supergroup have the generic formula M12+M23+M33+(XO4)2(OH)2·8H2O, where M1 = Fe2+, Mg2+, Mn2+; M3+ = Al3+ or Fe3+; and XO4 = PO4 or AsO4. The supergroup is divided into the laueite group (phosphates -currently seven minerals) and the maghrebite group (arsenates - currently two minerals).

NOMENCLATURE PROPOSALS APPROVED IN SEPTEMBER 2014

IMA 14-D: Thalénite-(Y)
Thalénite-(Y) is redefined as a F-dominant species with ideal composition Y3Si3O10F. The name ‘‘fluorthalénite-(Y)’’ is consequently discredited.

IMA 14-G: Clino-ferri-holmquistite
Proposal 14-G is accepted, and clino-ferriholmquistite is officially approved as ^A☐^BLi2^C(Mg₃Fe³⁺₂)Si₈O₂₂(OH)₂. Such compositions were originally described as ‘‘ferriottoliniite’’, but discarded in the latest report on amphibole nomenclature and classification [Hawthorne et al., American Mineralogist, 97, 2031-2048 (2012)].

REVISED CHEMICAL FORMULA

A paper on the mineral Nafertisite has been published recently [European Journal of Mineralogy, 26, 689–700 (2014)] in which the ideal chemical formula of the mineral is given as Na3Fe2+10Ti2(Si6O17)2O2(OH)6F(H2O)2. In this formula, F is now a major element, while it was absent in the previously accepted formula of nafertisite. These data were examined carefully by the CNMNC officers and were considered reliable. Accordingly it was agreed to modify the formula of nafertisite in the official IMA List of Minerals.

REVISED NAME AND END-MEMBER FORMULA

The new mineral IMA No. 1998-046 was approved under the name obertiite. In the original description of the new mineral obertiite [Hawthorne et al., American Mineralogist, 85, 236-241 (2000)] its end-member formula was given as NaNa2(Mg3Fe3+Ti4+)Si8O22O2. After the approval of the report of the amphibole subcommittee [Hawthorne et al., American Mineralogist, 97, 2031–2048 (2012)] the mineral was renamed ferri-obertiite, based on the rule that the rootname without prefix is for the Al-dominant end-member. A careful look at the chemical analyses on holotype material revealed that IMA 1998-046 has Mn3+ > Fe3+. Therefore the CNMNC officers decided to rename it as Mangani-obertiite, with endmember formula NaNa2(Mg3Mn3+Ti4+)Si8O22O2.

Hallo Stephan,

vielen Dank für Deine Mitteilung.

Zur Information bezüglich des letzten Abschnitts "revised names and end-meber formula" von Obertiit/Ferri-Obertiit/Mangani-Obertiit kann ich folgendes mitteilen:
Bei Mindat wird vermutet:
"Es wäre nicht überraschend, wenn sowohl ferri obertiite und mangani-obertiite in der Eifel vorhanden sind."
Dies ist nach meiner Meinung sehr wahrscheinlich.

  EDX und WDS-Analysen von verschiedenen Proben unterschiedlicher Fundorte zeigen immer Fe> Mn.
  Wenn alles Eisen  Fe3 + ist sollten es  alles Ferri-Obertiite sein. Nur der Obertiit aus der Originalbeschreibung wäre ein Mangani-Obertiit.

  Beispielsweise:
  Bellerberg 8 untersuchte Proben Fe / Mn zwischen 4/1 und 3: 2
  Emmelberg 1 Probe Fe / Mn = 3/1
  Herchenberg  Probe Fe / Mn = 4: 1
  Nickenicher Sattel 1 Probe Fe / Mn = 3: 1
  Nick. Weinberg 1 Probe Fe / Mn = 3: 1
  Wannenköpfe 1 Probe Fe / Mn = 3: 1
  Rothenberg 6 Proben Fe / Mn zwischen 3/1 und 3/2 (1 Probe 1.6 / 1.5)

herzliche Grüße ein gesegnetes Weihnachtsfest und fürs kommende Jahr weiterhin alles Gute und viel Erfolg

Hallo Günter,

vielen Dank für die interessanten Zusatzinformationen und die lieben Wünsche. Wir werden sicher noch von einem Mangani-Obertiit aus der Eifel hören. Bisher scheint die Fe-Mannschaft die stärkere zu sein, aber irgendwann bekommen die Mn auch mal Oberhand  .

Auch Dir ein fröhliches Weihnachtsfest und guten Rutsch mit allem was dazu gehört.
Herzlichen Gruß
Stefan

Hallo Stephan,
danke.

Von der Vulkaneifel (Bellerberg) gibt es den Mangani-Obertiit (Typmaterial Obertiit)!
Außerdem gibt es von hier nach N.V. Chukanov auch einen Ferro-Ferri-Obertiit.

Bei den restlichen, im vorherigen Beitrag von mir angeführten Proben kann es sich um eines der drei Obertiit-Minerale, Ferri-Obertiit, Ferro-Ferri-Obertiit oder auch um Mangani-Obertiit handeln. Um sie eindeutig zu definieren müsste das genaue Verhältnis Fe2+/Fe3+/Mn3+ bekannt sein. Kann ich leider selbst nicht machen. Bemühe mich aber entsprechende Proben an anderer Stelle untersuchen zu lassen!

MfG
Günter
