Nomenclature/classification proposals approved in September 2020

IMA 20-D: wöhlerite group

Proposal 20-D is accepted and the wöhlerite group is established. It currently includes nine mineral species: cuspidine, baghdadite, burpalite, låvenite, normandite, niocalite, janhaugite, wöhlerite, and hiortdahlite. The chemical formula of the latter mineral has been revised to Na2Ca4(Ca0.5Zr0.5)Zr(Si2O7)2OF3. Marianoite has been discredited as it is identical to wöhlerite.

Cerite supergroup

The cerite supergroup has been established and includes the cerite group (five members) and merrillite group (eight members). Cerite-(La) has been renamed ferricerite-(La) since Fe is dominant in the M site. It has the formula (La,Ce,Ca)9Fe3+(SiO4)3(SiO3OH)4(OH)3.

Bahariyait (= Kaliumpermanganat) ist ja schräg. Ist das überhaupt plausibel, das Mn(VII) sich in der Natur bildet und stabil ist?
Mich würde interessieren, was die anwesenden Mineralogen dazu meinen!

Danke für den Link! Wenn man das sieht (und vor allem die Bilder) fragt man sich in der Tat, ob die zuständige Kommission noch alle Tassen im Schrank hat. Das sieht doch eher so aus, also ob da jemand vor 10 Jahren ein Säckchen KMnO4 vergessen hat. Bizarr!

So recht vermag ich das neue, natürliche Mineral nicht zu glauben. Ich bin gespannt auf die Veröffentlichung.

Definitiv sehr interessant. Wenigstens wäre der Nachweis recht einfach. Einen Tropfen Glycerin drauf träufeln und es fängt an zu brennen.

Viele Grüße
Stefan
