Question 6
Compare samples K and L. Note that for each rock sample, two GigaPan views are provided.
One of these samples is a fault breccia; the other is a mylonite. Review the characteristics of fault breccia and mylonite with this SmartFigure video (Links to an external site.).
Which of these two samples, K or L, is the mylonite? Why?
K is the mylonite. It has chunks of garnet in it.
L is the mylonite. It has chunks of garnet in it.
L is the mylonite. It displays "augen" of several minerals, with "tails" that stretch out parallel to the foliation.
