Category: 0 1 2 3 4 5







Magmatic Isotropic: no shape fabric Weak shape fabric Moderate shape fabric Strong shape fabric








Crystal plastic Undeformed Weakly foliated Strongly foliated Porphyroclastic (proto)mylonite Mylonite Ultramylonite







Cataclastic Undeformed Minor fracturing: no significant grain-size reduction Moderate fracturing:
no significant grain-size reduction
Dense anastomosing fracturing and incipient breccia
(<20% matrix)
Well-developed fault brecciation; rotation of clasts (20% to 70% matrix) Cataclasite
(>70% matrix)







Joints Unfractured Minor fracturing
(1 per 10 cm)
(1 to 5 per 10 cm) (>5 per 10 cm)








Veins No veins Occasional veins
(= filled fractures)
(1 per 10 cm)
Moderate veining
(1 to 5 per 10 cm)
Intense vein networks (>5 per 10 cm)
