3. Nomenclature/classification proposals approved in December2019

IMA19-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.

IMA19-H: discreditation of heliophyllite
Proposal 19-H is accepted, and heliophyllite is discredited. This species is identical to ecdemite, Pb6As2O7Cl4.

4. 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 togetherwithNaassubordinatecations,acquirenowthestatus 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).
