NOMENCLATURE PROPOSALS APPROVED IN JULY 2018

Alluaudite supergroup

A new classification and nomenclature scheme has been approved for the minerals of the alluaudite supergroup. The supergroup is divided into the alluaudite group, the wyllieite group, and the bobfergusonite group.

Discreditation of fupingqiuite

As a side effect of the new classification of alluaudites, the mineral fupingqiuite (IMA 2016-087; see CNMNC Newsletter 35) is not a separate species from varulite and has been discredited.

Fupingqiuite page updated.

Note:

Wumuite:

CNMNC Newsletter No. 44 name the locality with this string: "Nanyang Village, Huaping Co., Panzhihua-Xichang region, China", in Mindat ( with the same coordinates) we have "Nanyang, Huaping Co., Lijiang Prefecture, Yunnan Province, China" [https://www.mindat.org/loc-263087.html]

Goldschmidtite:

Is the spacegroup correct ? Not Pm-3m?

Btw. this mineral has been given the same name as Goldschmidtite, a synonym of sylvanite [https://www.mindat.org/min-7543.html] (now renamed Goldschmidtite (of Hobbs), so they are not confused in the database)

9th Aug 2018 18:40 UTCKnut Edvard Larsen 🌟 Manager

The cell parameters for cerromojonite seems to not be complete (β is lacking).

Except that, all new minerals are now added/updated to the database.

The pages for the references needs to be added when the paper is published.

>> The cell parameters for cerromojonite seems to not be complete (β is lacking).

I think that cerromojonite can be orthorhombic, like the analogue součekite.

Goldschmidtite space group is Pm-3m.

I see the following Hg mineral has no name , it is a mistake ?

IMA No. 2018-029

Hg2+3[NHg2+2]18(Cl,I,OH,Br,S)24

Clear Creek mine, New Idria mining district, San Benito Co., California, USA (120°43’58”W, 36°22’59”N)

And it is some of the unknowns labeled as CCUK-xx in Mindat and in the below Record article ?

Dunning, G.E., Hadley, T.A., Magnasco, J., Christy, A.G., Cooper Jr., J.F. (2005) The Clear Creek mine (San Benito County, California): a unique mercury locality. The Mineralogical Record: 36(4): 337-363.

Many thanks

> I see the following Hg mineral has no name , it is a mistake ?

The authors of an approved IMA proposal are given the option to omit the name of a new mineral in such lists.

12th Aug 2018 23:54 UTCTed Hadley

It is CC UK #10. The name will be released once the arguing has died down.

Ted - do you know if anyone is working in CCUK-8? I may have some if more is needed for characterization.

13th Aug 2018 02:40 UTCTed Hadley

Thanks anyway, Jeff, but CC UK #8 is common stuff and we have a ton of material.

It is apparently a hydrated secondary too fine grained for single crystal analysis. Unless technology improves the ability to do single crystal analysis with nearly amorphous powders containing big mercury ions, it will never be finished.

All "crystals" of #8 have turned out to be edoylerite, from which #8 is derived (we think).

>do you know if anyone is working....

That is our real problem. There is no one to work on these things. Mark Cooper had done most of the recent work, but he is busy with other things, and these minerals are difficult. Many academics flat out refuse to work on them. We still have around 12 Clear Creek Mine things to characterize and publish and we have about 15-20 more new mercury species from another locality, all waiting for attention.

Many thanks Ted for your answer and your interesting comments on the unknowns.

THe mindat.org name is more accurate. The IMA locality name is odd.

18th Aug 2018 21:04 UTCRoy Kristiansen Expert

Please be aware that the new mineral name zinconigerite, IMA 2018 - 037, discovered in Xianghualing in PRC, have already been used by Chukanov et al. 2016, vol. 2, p.193 in their book on IR spectra of minerals and related compounds.See spectra O 267. Their mineral is from Erongo in Namibia, but they never submitted it to the Commission.

It is identical to the Chinese.
