The information given here is provided by the IMA Commission on New Minerals, Nomenclature and Classification for comparative purposes and as a service to mineralogists working on new species.

Each mineral is described in the following format:

Mineral name, if the authors agree on its release prior to the full description appearing in press

Chemical formula

Type locality

Full authorship of proposal

E-mail address of corresponding author

Relationship to other minerals

Crystal system, Space group; Structure determined, yes or no

Unit-cell parameters

Strongest lines in the X-ray powder diffraction pattern

Type specimen repository and specimen number

Citation details for the mineral prior to publication of full description

Citation details concern the fact that this information will be published in the European Journal of Mineralogy on a routine basis, as well as being added month by month to the Commission’s website.

It is still a requirement for the authors to publish a full description of the new mineral.

NO OTHER INFORMATION WILL BE RELEASED BY THE COMMISSION

NOMENCLATURE PROPOSALS APPROVED IN AUGUST 2018

IMA 18-D: Redefinition of the ideal formulae for mottanaite-(Ce) and ciprianiite

The proposal 18-D is accepted. Accordingly, the ideal formula of mottanaite-(Ce) is changed from Ca4(Ce,Ca)2AlBe2[B4Si4O22]O2 to Ca4Ce2Al(Be1.50.5)Σ2[B4Si4O22]O2, and the ideal formula of ciprianiite is changed from Ca4[(Th,U)REE]Σ2Al□2[B4Si4O22](OH)2 to Ca4[(Th,U)Ca]Σ2Al(Be0.51.5)Σ2[B4Si4O22](OH)2.
