A crustal-scale shear zone network at the fossil brittle-to-viscous transition exposed at Cap de Creus, NE Spain evolved by coeval fracturing and viscous, mylonitic overprinting of an existing foliation.

In this paper, we report a series of deformation experiments on polycrystalline norcamphor, a quartz analogue material, that were designed to characterize the relationship between strain localization and fluid migration in crustal rocks undergoing mylonitic ...

A theoretical, composite flow law is presented for mylonite containing interconnected layers of a weak mineral undergoing power law creep and porphyroclasts of a stronger mineral undergoing fracture and frictional sliding.
