Strain Patterns in Rocks is a selection of papers presented at the international workshop, held in Rennes on May 13-14, 1982. The book presents papers on the techniques of strain measurement; an orthographic analysis of deformation; and the applications of the Mohr circle to inhomogeneous deformation. The text also includes papers on the methods of strain removal; a general transformation to simulate heterogeneous strain states; the significance of isotropic points; and the detection of volume changes. Papers on the analyses of strain discontinuity at interfaces; strain refraction through contrasting layers; and strain patterns in ductile shear zones and at the tips to shear and thrust zones are also considered. The book further includes papers on the natural strain patterns: in mylonite zones, in granites, in Alpine nappes, in linearly anisotropic rocks, in an ice cap and in a boudin model.
