A set of discrimination diagrams have been derived from a statistical studyof the Ti, Cr, Ca, Al and Na contents of over 706 analyses of calcic clinopyroxene phenocrysts from recent volcanic rocks of various magmatic types from various tectonic settings. Using these diagrams three major basaltic groups can be distinguished with greater than 80% confidence: alkali basalts and related rocks, tholeiites from spreading centres and orogenic basalts. These diagrams can be used to identify the magmatic affinities of paleo-volcanic series where, in spite of metamorphic or metasomatic transformations, primary clinopyroxene phenocrysts are commonly preserved. This method is applied succesfully to six examples of Mesozoic to Paleozoic metabasites and spilitized volcanic rocks.
