CNMNC Approved Proposals - summary

IMA Commission on new minerals, nomenclature and classification (CNMNC) Newsletters

A. Open issues:

• Lazurite is questionable, all known lazurites are a sulfide rich mineral variety of haüyne (MinDat: Moore & Woodside, 2014)
• Titanium disilicates - block (TS-Block) minerals

B. Open issues:

• RRUFF structural groups: pyrite, ullmannite and cobaltite
• Synonyms of gold amalgam: goldamalgam (of Chen et al., rejected), unnamed (Au₂Hg), weishanite, yiyangite
• Iron silicides: fersilicite^N, naquite, ferdisilicite^N, linzhiite
• Nickelalumite^N: crystal structure solved (Uvarova et al., 2005)
• Vaterite: it might need a redefinition. It is metastable below approx. 400°C. It might be stabilised by sulfate (Fernández-Díaz et al., 2010). It might be a mixture of two nanodomains (Kabalah-Amitai et al., 2013).

• As something of a compromise following 'Special Voting Notice 2004-01'/ 'Voting Proposal 09-D'
• A minimum set of data has been published on the Commission’s website after each mineral has been accepted. This includes IMA number, type locality, name of first author, chemical formula and structural relationship, as well as unit-cell dimensions and strongest lines in the PXRD pattern.

IMA/CNMNC List of Mineral Names (March 2009) (Q15205595)

Draft: IMA Master List (March 2007)

• Supplied through the courtesy of Materials Data, Inc. (Nickel, E.H. and Nichols, M.C.)

• RRUFF Project (rruff.info/ima/), Mineralogy and Crystallography, Department of Geosciences, University of Arizona. The mineral list on the Rruff Project website was built up with the IMA Master List (March 2007); it is the first version of the fusion of the ARD List (approved, revalidated and discredited minerals) with the GQN List (grandfathered, questionable and published without IMA CNMNC approval minerals).

The final GQN List got published (grandfathered, questionable and published without approval) after a final review of Burke E A J and Nickel E H (approved decision 'IMA 2006-C', December 2006).

19th General Meeting of IMA, Kobe, Japan (July 2006).

• The merging of the Commission on New Minerals and Mineral Names (CNMMN) and the Commission on Classification of Minerals resulted in the Commission on New Minerals, Nomenclature and Classification (CNMNC).
• It was decided to create a website presenting the "official" IMA list of minerals.
