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.

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.
