Abstract
Compositional variations of the epidote-supergroup minerals from various magmatic, metasomatic and metamorphic formations of the Pelagonian Massif (Republic of Macedonia), the Urals (Russia) and the Eifel Mountains (Germany) have been studied and new data on isomorphism in these minerals have been obtained. Nine potentially new mineral species belonging to the epidote supergroup were identified, including minerals in which Cr, Ga, La, Ce, Nd and Pb are the species-defining components, as well as a number of varieties with unusually high Zn and Cu contents. Relationship between the chemical composition of epidote-supergroup minerals and their Raman spectra is discussed.
Key words: minerals of epidote-supergroup, typomorphism, Raman spectra, Pelagonian massif, Republic of Macedonia
