Nomenclature proposals approved in November 2011

IMA 11-C: The proposal to redefine matulaite
has been approved. The ideal formula of
matulaite becomes Fe3+Al7(PO4)4(PO3OH)2(OH)8(H2O)8·8H2O.
Specimens NHMLAC 28324 are designated as the
neotypes for the species, and are deposited in
collections of the Natural History Museum of
Los Angeles County, Los Angeles, USA.

IMA 11-E: The proposal to redefine vanadiumdravite
has been approved. Vanadium-dravite is
renamed oxy-vanadium-dravite, since the
mineral belongs to the alkali group, oxysubgroup
3 of the tourmaline supergroup
nomenclature. The ideal formula of the
mineral becomes NaV3(V4Mg2)Si6O18(BO3)3(OH)3O.

IMA 11-F: The proposal to modify the
nomenclature of the hollandite supergroup has
been approved. Hollandite is redefined as the
Ba2+-Mn3+ endmember of the coronadite group,
with an ideal formula Ba(Mn4+6Mn3+2)O16, and
the name ferrihollandite is introduced to
designate the Ba2+-Fe3+ endmember of this
group , with an ideal formula
Ba(Mn4+6Fe3+2)O16. The mineral ankangite is
discredited, since it corresponds to mannardite.
Moreover, the ideal endmember formulae of six
potentially new species in the hollandite supergroup
are defined.

Nomenclature proposals approved in April 2012

AMPHIBOLE SUPERGROUP: A new
nomenclature scheme for the amphibole supergroup
was approved by CNMNC on the 3rd of April 2012.

GARNET SUPERGROUP: A new nomenclature
scheme for the garnet supergroup was
approved by the CNMNC on the 3rd of April,
2012. The garnet supergroup includes at present
32 valid species, for which endmember
formulae are given. There are 4 potential new
mineral species which need further study in
order to be approved. Some changes among
existing mineral names were also approved.

No, at this moment. Any paper.

Surely it is a mistake on the IMA list. Stuart can help us to solve the problem.

Fuxiaotuite appears to be the same as "clinotyrolite" which was published without approval and later considered as invalid. Also note that the TLs given for Fuxiaotuite are the same as those previously specified for clinotyrolite.

Luanshiweiite: The TL is GUANpo (官坡; 官 = Guan in the official transliteration), not GUANGpo. The "n-ng-dyslectics" are still a big problem with Chinese locality names and cause a lot of confusion.

And tellurocanfieldite (which is not sulfur-free) is possibly be the same as the "tellurian canfieldite with a particularly high tellurium content" that has been previously reported from several localities including Bajiazi.

It is the same mineral as "clinotyrolite" but as all tyrolite is monoclinic and this mineral is definitely not tyrolite the name change was approved in the IMA accepted proposal.

This makes no sense. Should clinoenstatite be called something new because all enstatite is orthorhombic?

Tellurocanfieldite is here given as a member of the Argyrodite-Canfieldite series. I've no objection to this, as I've long thought "series" could have multiple end-members, but usually I get overruled by those who insist a series can have only 2 end-members
avatar
Rob Woodside June 25, 2012 08:04PM
2 member series are are just a way of describing solid solutions. Until I was caught by the pedantry of 2 members, I and everyone I talked to understood that solid solution series described the full set of 2 member series that describe the solid solution. Don't worry about it Alfredo, leave the 2 member series to the dimesionly challenged pedants and speak freely about solid solution SERIES with several end members.

Given the information in the above note the crystal structure of "tellurocanfieldite" it would not be resolved. The words "structure determined" are not in the text.
I call the attention to the fact that Bindi et al. (2012) have recently presented a paper on Te-rich canfieldite from Lengenbach.
Here is the abstract.
The study with SCXRD performed by Bindi et al. (2012) on the sample from Lengenbach, with nearly identical chemical composition, shows that the Te atoms are disordered in the relevant five structural sites (none of them predominates in tellurium), and the phase, as demonstrated by several tests, is cubic and not orthorhombic.
Not having been observed as reported by Chinese authors in the proposal (check list) I do not have all the elements for a good judgment, but I would say that the proposal and approval deserve a reassessment in order to well understand if the compound has indeed all the qualifications to be recognized as a new mineral species.

Abstract:
In order to evaluate the effects of Te-for-S substitution in the minerals of the argyrodite group, the crystal structure and chemical composition of a crystal of Te-rich canfieldite from the Lengenbach quarry, Binntal, Switzerland, was investigated. The unit-cell parameters are a 11.0003(6) Å and V 1331.1(1) Å3. The structure was solved and refined in the space group F4-3m to R1 = 0.0308 for 194 independent reflections and 21 parameters. Quantitative analysis led to the chemical formula Ag8.05(Sn1.03Ge0.01)∑1.04(S3.95Te1.95Se0.01)∑5.91, ideally Ag8Sn(S,Te)6. The crystal structure of Te-rich canfieldite was found to be topologically identical to that of putzite, (Cu4.7Ag3.3)GeS6. Neglecting the short Ag-Ag contacts (due to disorder), the two Ag atoms in the structure can be considered as three-fold (Ag1) and four-fold (Ag2) coordinated. Tin adopts a regular tetrahedral coordination. The refinement of the site-occupancy factor indicates Te to be disordered over the three anion positions (i.e., X1, X2, and X3), with a preference for the X1 site.

The chemical formula for Fuettererite, as listed in the IMA CNMNC proprosal by Marco Ciriotti, is incorrect. Tony Kampf has corrected it on the Fuettererite mineral page. The correct formula is Pb3Cu6TeO6(OH)7Cl5.

Perhaps I should have added that tyrolite is not orthorhombic and it makes no sense to rename it clinotyrolite. The mineral that was known as clinotyrolite has a different chemistry and structure. Clino-enstatite is a polymorph (ie chemically the same) with only the crystal structure being different.

Peter Haas August 25, 2012 03:54PM
Re: Tellurocanfieldite:

Tellurium-rich canfieldite has been long known from Bajiazi (Li, Y. and Qing, C.K. (1999): Acta Mineralogica Sinica 19, 426-435), which is now also the TL of tellurocanfieldite. If we disregard the possibility that it is in fact a variety and not a new mineral, the formula with "Te2S4" suggests that there either are two different anion sites or there is a phase transition (structural change) occurring with increasing tellurium content in canfieldite. Both observations imply that there was at least some preliminary structure research carried out.

2012 MINERAL APPROVAL WITHDRAWN

IMA No. 2012-013 Tellurocanfieldite
Approval for this mineral has been withdrawn
(Gu, X., Xie, X., Lu, A., Hoshino, H., Huang, J.
and Li, J. (2012) Tellurocanfieldite, IMA 2012-
013. CNMNC Newsletter No. 13, June 2012,
page 816; Mineralogical Magazine, 76,
807_817). A subsequent single-crystal structural
analysis has shown that Te is disordered
over the three sulfur sites and thus the material
is in fact Te-rich canfieldite.

"Fuxiaotuite appears to be the same as "clinotyrolite" which was published without approval and later considered as invalid. Also note that the TLs given for Fuxiaotuite are the same as those previously specified for clinotyrolite."

"It is the same mineral as "clinotyrolite" but as all tyrolite is monoclinic and this mineral is definitely not tyrolite the name change was approved in the IMA accepted proposal."


In fact, the space group is identical with and the unit-cell parameters are very close to those of the 2M-polytype of tyrolite (C2/c; a = 54.520(6), b = 5.5638(6), c = 10.4647(10) Å, beta = 96.432(9)°; Krivovichev et al., 2006).
I first thought: shouldn't fuxiaotuite be just considered a polytype of tyrolite and therefore discredited?
Then I noticed that tyrolite is defined as a SO4-free, but CO3-bearing species, and fuxiaotuite as a SO4-bearing, but CO3-free species. I am really looking forward to see the crystal structure and how its details were determined.
