Newsletter 75

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 (ideal formula)

Mineral symbol

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 website.

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

NOMENCLATURE/CLASSIFICATION PROPOSALS APPROVED IN AUGUST 2023

IMA 23-G: redefinition of georgeite

(Mike S. Rumsey)

Proposal 23-G is accepted, and georgeite is redefined as an amorphous alpha-phase hydroxide with the generic formula [Cu(OH)_2–x(H₂O)_x][CO₃]_x/2.

IMA 23-H: revalidation of testibiopalladite

(Louis J. Cabri & Qing-Lin Liang)

Proposal 23-H is accepted, and testibiopalladite, originally described from a unspecified occurrence in China [Geochimica, 3, 169-181 (1974)], is recognized as a valid mineral species with ideal formula PdSbTe.
