The information given here is provided by the IMA Commission on New Minerals, Nomenclature andClassification 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 Mineralogical
Magazine 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
