Correspondence: Marco Pasero (marco.pasero@unipi.it)

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 X-ray powder 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 European Journal of Mineralogy 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.

IMA 20-D: wöhlerite group

Proposal 20-D is accepted and the wöhlerite group is established. It currently includes nine mineral species: cuspidine, baghdadite, burpalite, låvenite, normandite, niocalite, janhaugite, wöhlerite, and hiortdahlite. The chemical formula of the latter mineral has been revised to Na2Ca4(Ca0.5Zr0.5)Zr(Si2O7)2OF3. Marianoite has been discredited as it is identical to wöhlerite.

Cerite supergroup

The cerite supergroup has been established and includes the cerite group (five members) and merrillite group (eight members). Cerite-(La) has been renamed ferricerite-(La) since Fe is dominant in the M site. It has the formula (La,Ce,Ca)9Fe3+(SiO4)3(SiO3OH)4(OH)3.
