The more common minerals found in such rocks include quartz, orthoclase, muscovite, chlorite, serpentine, talc, and epidote; carbonate minerals and amphibole (actinolite) may also be present. The green colour of many of these minerals and their platy habit cause the rocks to be greenish and schistose (having a tendency to split). 2, record 1, English, - greenschist%20facies

Le faciès des schistes verts est caractérisé par la stabilité de l'association amphibole calcique non alumineuse (actinote-trémolite) + plagioclase acide (albite ou oligoclase renfermant moins de 20 p. 100 d'anorthite). La biotite peut apparaître dans la partie la plus métamorphique de ce faciès. 2, record 1, French, - faci%C3%A8s%20de%20schistes%20verts
