New minerals and nomenclature modifications approved in 2019

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

NOMENCLATURE/CLASSIFICATION PROPOSALS APPROVED IN JUNE 2019

IMA 16-F: Changes to CNMNC procedures regarding combustion products forming on burning coal dumps

Proposal 16-F is accepted. Crystal phases forming on the burning coal dumps with no human agency initiating the fire and no anthropogenic material deposited there should be treated as minerals.

IMA 19-C: Establishing a new class of type specimen – Anthropotype

Proposal 19-C is accepted. Synthetic analogues, used to justify the existence of a new mineral species or to obtain the missing properties required for a new mineral characterisation, are designated as anthropotypes. These anthropotypes should be registered and stored in museums, and made available for study just like naturally occurring type specimens.

POLISH-UP OF THE IMA LIST OF MINERALS

We are making effective a number of minor changes in the chemical formulae of minerals which, in their current form, have been inherited from previous IMA-approved compilations. In most cases the change merely consists in the elimination of subordinate constituents occurring within the same parentheses together with the dominant constituent. Minerals marked as Q (questionable) in the IMA List of Minerals were not considered, since these should deserve a more detailed re-appraisal. Similarly, minerals belonging to a supergroup for which the IMA-CNMNC approved a comprehensive report were left behind, too, as those formulae have been already discussed and agreed by a dedicated subcommittee. This is an executive decision taken by the officers of the IMA-CNMNC.
