Nomenclature of the micas
End-members and species, defined with permissible ranges of composition, are presented for the true micas, the brittle
nicas, and the interlayer-deficient micas. The determilation of the crystallochemical formula for different available chemical
data is outlined, and a system of modifiers and suffixes is given to allow the expression of unusual chemical substitutions
or polytypic stacking arrangements. Tables of mica synonyms, varieties, ill-defined materials, and a list of names formerly or
erroneously used for micas are presented. The Mica Subcommittee was appointed by the Commission on New Minerals and
Mineral Names of the Intemational Mineralogical Association. The definitions and recommendations presented were approved
by the Commission
