Deformation of paraffin wax to an annular shear strain of 18.0 rad /cm at outer shear zone boundary
At a 20x magnification and under cross-polarised light we observed a well developed S-C' Type cleavage with foliated microlithons. Thirteen pictures separated by time steps of 4 minutes were used for analysing the movement of 100 markers and the vorticity distribution Wn (Movie 4). The contour plots of Wn show super-simple shear in two directions in the S-C' fabric.
