“Several text symbol lists for common rock-forming minerals
have been published over the last 40 years, but no internationally
agreed standard has yet been established. This contribution
presents the first International Mineralogical Association (IMA)
Commission on New Minerals, Nomenclature and Classification (
CNMNC) approved collection of 5744 mineral name abbreviations
by combining four methods of nomenclature based on the Kretz
symbol approach.”
