Each mineral is described in the following format: IMA Number Chemical Formula (any relationship to other minerals; structure analysis) Crystal system, space group Crystal unit-cell parameters Color; luster; diaphaneity Optical properties Strongest lines in the X-ray powder-diffraction pattern [d in Å(I)] The names of these approved species are considered confidential information until the authors have published their descriptions or released information themselves. No other information will be released by the Commission. * Chairman, CNMMN. E-mail address: jgrice@mus-nature.ca ** Vice-chairman, CNMMN.
