Information about the distribution of vorticity number W_n, area change A_f and strain ration R_f along the S-C fabric is given in (Movie 5). Four pictures were used for analysis of Movie 5 are separated by time steps of 22 minutes. 100 markers were digitised for the four pictures. The R_f plots show a dominant value of 1.5 along the S-C' fabric while the surrounding areas were less or not deformed (R_f value close to 1). With time the gradient to the less deformed areas becomes steeper, but the more strained areas widen in the shear band (C') direction. W_n (Movie 6) shows high values around the S-C' fabric, indicating an approach of a super-simple shear (DePaor 1988) in several directions. On the left hand side of the image are domains with negative W_n. Domains of simple shear (W_n =1) are located within the S-C' cleavage and a pure shear component (W_n = 0) is noticeable along the shear band (a). The S-C' fabric is not situated in a simple shear environment.
