Deformation of paraffin wax to an annular shear strain of 6.0 rad /cm at outer shear zone boundary
At a 10x magnification and under cross-polarised light we observed localisation of deformation into shear bands (a, b) with the same shear sense as the imposed bulk shear. Left picture shows the situation at shear strain rate of 2.9 at outer shear zone boundary. The movie shows the S-C' type cleavage with oblique shear bands (C') and microlithons (Passchier & Trouw 1996). The microlithons rotated with respect the shear zone boundary, as is clearly visible. The movie consists of picture with laps of 320s
