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

REVISED CHEMICAL FORMULAE

Hellandite-(Ce) and hellandite-(Y)

In the IMA List of Minerals the chemical formulae of hellandite-(Ce) and hellandite-(Y) were inconsistent with those given in the IMA-approved report on hellandites [Am. Mineral., 87 (2002), 745–752].

In both formulae the occupancy at the T sites was given as (Be,Li)2x, however the value of x was not specified. Actually it is always x > 1, therefore the T site is vacant in the ideal formulae of hellandite-(Ce) and hellandite-(Y). Now both formulae have been modified accordingly: (Ca,REE)4Ce2Al☐2(B4Si4O22)(OH)2 and (Ca,REE)4Y2Al☐2(B4Si4O22)(OH)2, respectively.
