Photomicrographic under crossed nicols of the entire annular shear zone at different finite strains. The place of the movie 2, 3 and 4 are signed.Figure a-d show the development of microstructurs in the entire sample. The finite strain was outer shear zone boundary at a 1.3, at b 6.0 at c 8.4 and at d 18.3. The white lines indicate some shear bands (c') and thrust in the experiment. All four pictures were rotated relative to the fix point P.
