Plastic deformation of rocks in the Earth is most strikingly illustrated in exposures of shear zones. Very large strains (shear strains of γ = 10 or more) may be developed in these zones. They appear to be ubiquitous within the continental and oceanic crust and may provide the dominant locus for deformation in these regions and, potentially, also in the lithospheric upper mantle. It is therefore of the greatest interest to obtain information about the deformation properties of rock at large strains

In the past, various approaches have been made to achieving in the laboratory the types of deformation seen...
