1 The modal compositions of amphibolites show that most of them contain more than 50% of amphibole but those with 50 to 30% are not unusual The content of amphibole and plagioclase together is mostly higher than 90% and may be as low as 75% 2 The colour of amphibole is green brown or black in hand specimen and green or brown in thin section
