“…CHLORINE-BEARING potassium amphiboles are typical of metasomatites from ore deposits, particularly iron-ores, but sometimes occur in granites, potassic syenites, and gneisses (Krutov, 1936;Hallimond, 1947;Ontoev, 1958: Geijer, 1960Serdyuchenko, 1960;Kalinin, 1983;Lobanova, 1963;Pavlov, 1964;Deer et al, 1965;Vakhrushev, 1965;Knyazev, 1966;Kostyuk, 1970;Leake, 1978;Dick and Robinson, 1979;Minerals, 1981;Sharma, 1981;Kamineri and Bonardi, 1982).
