The mechanism of shear zone formation in lower crustal, relatively “dry” rocks is still poorly
understood. We have studied the high-temperature deformation of the Hasvik gabbro (northern Norway)
which commences by fracturing. The 10–20 μm wide fractures show little displacement. The fine-grained
plagioclase and orthopyroxene in the fractures lack a crystallographic preferred orientation (CPO) or ...
