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 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 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 FORMULA

After the approval of the new mineral markeyite (IMA No. 2016-090; see CNMNC Newsletter 35), the authors of the proposal communicated results of subsequent analytical work on this mineral, which shows higher contents of CO2 and lower concentrations of H2O. The new data were examined carefully by the CNMNC officers and were found reliable. The new revised simplified formula Ca9(UO2)4(CO3)13·28H2O has been approved executively.
