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 powder X-ray 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 Mineralogical Magazine on a routine basis, as well as being added month by month to the Commission's web site.
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/CLASSIFICATION PROPOSALS APPROVED IN DECEMBER 2019
IMA 19-G: discreditation of ferrotellurite
Proposal 19-G is accepted, and the ill-defined mineral ferrotellurite is discredited. Indeed, this species has been shown to be equivalent to keystoneite, Mg0.5NiFe3+(Te4+O3)3⋅4.5H2O.
IMA 19-H: discreditation of heliophyllite
Proposal 19-H is accepted, and heliophyllite is discredited. This species is identical to ecdemite, Pb6As2O7Cl4.
REVISED CHEMICAL FORMULA
A paper on the mineral ilmajokite has been recently published [IUCrJ, 7 (2020), 121–128] in which the ideal chemical formula of the mineral is given as Na11KBaCe2Ti12Si37.5O94(OH)31⋅29H2O. With respect to the previously accepted formula, there is a new chemical element (K); moreover Ba and Ce, which were previously put together with Na as subordinate cations, now acquire the status of species-forming constituents, as the structural study clearly indicates that they are partitioned at specific crystallographic sites. These data were examined carefully by the CNMNC officers and were considered reliable. Accordingly it was agreed to modify the formula of the mineral in the official IMA List of Minerals. Moreover, the occurrence of a REE as a species-forming element implies the renaming of ilmajokite to ilmajokite-(Ce).
ERRATUM
The file on the new mineral petrovite in CNMNC Newsletter 52 was wrong in the following details: IMA No.; chemical formula; full authorship of proposal; unit-cell parameters; strongest lines in the X-ray powder diffraction pattern; citation details for the mineral prior to publication of full description.
