BHQ deformed by a combination of sinistral simple shear (g = 2.1) and shortening (~50%) at 800°C, 10-5/sec and 1200 MPa; regime 2 dislocation creep.

BHQ deformed by a combination of simple shear (g = 2.1) and axial compression (shortening ~50%) at 800°C, a shear strain rate of 10-5/sec and 1200 MPa (regime 2). The shear zone boundaries are parallel to the horizontal edges of the photo; shearing was sinistral. Note that the recrystallized grains, which result from progressive subgrain misorientation, define a foliation which is oblique to the shear plane (and which does not change in angle with progressive strain).
