Summary:A recent study of petrological nomenclature shows that the derivations of English rock names are numerous. The greatest number, 30%, were derived from geographical terms; oceans, countries, states, towns and others. Second in abundance, over 15%, are terms derived from Greek, generally related to a mode of formation or to a rock property. Over 11% were derived from older rock names by modifying the name in some way, for example by using prefixes or suffixes, like syenitite, syenitoid. Also of importance are common English names (10%), like limestone, silt, slate, and rock names derived from mineral names (8%), like quartzite, magnetitite, spinellite. Latin terms are sixth in abundance (<7%). Many other derivations exist. Less than 100 honour names of persons (charnockite, dolomite); some are portmanteau words, formed by combining parts of existing words. Numerous languages and dialects from all over the world have contributed their share of terms. [R.S.M.]
