Please consult a review of the Commission activities
and a list of Commission decisions since 1959.
The IMA-CNMMN has published over the past twenty-five years
in several mineralogical journals many official reports which contain the rules
and regulations about all aspects of the nomenclature of minerals and a number
of mineral groups. The following lists give an overview:
General mineralogical nomenclature
- Definition of a mineral
- Formal definitions of type mineral specimens
- Protocols on the depositions of investigated mineral specimens
- Procedures and guidelines on mineral nomenclature, 1998
- Solid solutions in mineral nomenclature
- Names, prefixes and suffixes, and adjectival modifiers
- Standardization of polytype suffixes
- Definitions of polytypism, topotaxy, syntaxy, epitaxy
- Format for chemical formulae and symbols for crystallographic axes and repeat distances
- Discreditation of mineral species
- Mineral names applied to synthetic substances
Nomenclature of mineral groups
- Platinum-group-element alloys
The reports mentioned in the these two lists have been compiled in a booklet form
by the Mineralogical Association of Canada and the Canadian Mineralogist on the occasion
of the IMA 17th General Meeting in Toronto (August 1998).
The booklet is available in two formats:
