Can't verify if Changesite-(Y) was approved by the IMA

Changesite-(Y) does not appear on the latest September list of Approved Mineral Names released by the International Mineralogical Association's Commission on New Minerals, Nomenclature and Classification (IMA-CNMNC):

http://cnmnc.main.jp/

It's also not in the most recent CNMNC newsletter, where the names of new approved minerals are published:

https://ejm.copernicus.org/

So I am not able to verify that Changesite-(Y) was indeed approved by IMA-CNMNC.

Maybe I missed something, perhaps a peer review article showing it is indeed a new and valid mineral species was published in an obscure Chinese language journal or there's an article in press and China has jumped the gun in announcing its approval?

Formula dubious

I'm tempted to blank the formula that's been presented in the lede. 1/ It does not appear in any of the Chinese or English language announcements regarding the mineral, or in any publication of any kind that I can find. 2/ It's not a properly formatted formula. I'm not expecting to see ion charges within a stable mineral compound formula. 3/ It appears stoichiometrically dubious. Yttrium is almost always trivalent, and I'm not expecting it to replace sodium.

Anyone got any hints about where it came from?

The following webpage is the original news release, there is no formula given. The unit cell structure of Changesite-(Y) is shown (software used is Vesta), might be possible to guess what elements are present. The SEM image shows Changesite-(Y) occurs as tiny inclusions within olivine, along with feldspar, cristobalite and baddeleyite. --Diamonddavej (talk) 16:06, 27 September 2022 (UTC)[reply]

The chemical formula was added to this article on 15 September 2022 by User:Almeo. Perhaps this editor can give a source reference citation? GeoWriter (talk) 21:19, 27 September 2022 (UTC)[reply]

This source in Chinese (referenced from the CN Wikipedia version of this article) gives the formula: sohu.com. There is also a Reddit page (not that I think it is a serious source, but oh well...) mentioning the formula. By the way the formula in CN Wikipedia was predating my edit. Here is the diff of the addition on the CN Wikipedia page. (It's not from me, I don't speak Chinese. It's a user I don't know. But it probably comes from the sources referenced at the bottom) Almeo (talk) 13:02, 29 September 2022 (UTC)[reply]
